A model of Greenland climate, using inputs of weather data and forecasts as well as the physical properties of the ice sheet, has estimated the total amount of melt during the extensive melt event. In some areas the ice cannot flow over the landscape via the historical pathways. Each AWS is equipped with a number of instruments to sample the following: air temperature, wind speed, wind direction, humidity, pressure Google Earth must be installed to use this search tool. The image gallery below shows the mean-monthly ice surface temperature (IST) of the Greenland Ice Sheet (left image), and the number of days of data available that month for each grid cell (right image). This does not include the imbalance caused by ice flow. The estimates come from a model based on daily weather measurements. The daily image update is produced from near-real-time operational satellite data, with a data lag of approximately one day. It is very cold all year long. Widespread thermometer measurements of temperatures only extend back to the mid-1700s. Air temperatures above Greenland were generally near average over the summer months this year (Figure 3). Denmark and Greenland have some of the longest published temperature data series in the world, dating back to 1768 and 1784, respectively. 2020. The Danish Meteorological Institute, which has a key role in monitoring Greenland’s climate, last week reported a shocking August temperature of between 2.7C and 4.7C at the Summit weather station, which is located 3,202m above sea level at the the centre of the Greenland ice sheet, generating a spate of global headlines.

See our, Exchange for Local Observations and Knowledge of the Arctic (ELOKA), NASA Distributed Active Archive Center at NSIDC (NSIDC DAAC), All About Arctic Climatology & Meteorology. This can be compared to the major melt and ice loss years of 2012, 2019, and others in the last decade with values between 225 and 325 billion tons below average (Figure 5b). Observations around the ice sheet margin (b-d) show new details about how the ice sheet is responding (faster flow in red, slower in blue). These maps reveal substantial reconfigurations of several major glaciers (Figure 6). This graph shows surface mass balance (SMB) for Greenland’s 2019 to 2020 autumn-winter-spring season (red line) relative to a 1981 to 2010 reference period. Interactive Map Select study locations by region, proximity to a point, or text-based attributes. The daily image update isn’t current; why? Thule, near a large US military base in northwestern Greenland, had a much warmer than average summer, but was still cooler than Nuuk, which is nearly 1,500 kilometers (580 miles) to its south. The peak melt day for 2020 was on July 10, when 551,000 square kilometers (213,000 square miles), or 34 percent of the ice sheet surface, melted. 3.

Eismitte, Greenland - Travel and vacation weather averages, current conditions and forecasts. When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow. This is known as a tundra climate. Looking for facts and information? Melting was moderately intense in the northeastern region but less so in the southwest, where in recent high-melt years the ice sheet has been losing mass and exposing bare ice. Based on weather reports collected during 1985–2015. Since 2000, the ice sheet has experienced a general increase in melting, with melt-day area for 2019 totaling 28.3 million square kilom… By Dr. Xavier Fettweis, University of Liège. Areas along the coast are masked out because the satellite sensor’s resolution is not fine enough to distinguish ice from land when a pixel overlaps the coast. Figure 6. We post analysis periodically as conditions warrant. Nuuk, the capital of Greenland on the central southwestern coast, had summer temperatures very close to average for that region. The thickness of the ice is approximately 1500 meters (59 055 inch). In Nuuk, the average daily temperature varies over the seasons from −5.1 to 9.9 °C (23 to 50 °F) The total area of Greenland is 2,166,086 km 2 (836,330 sq mi) (including other offshore minor islands), of which the Greenland ice sheet covers 1,755,637 km 2 (677,855 sq mi) (81%) and has a volume of approximately 2,850,000 km 3 (680,000 cu mi). Journal of Geophysical Research: Earth Surface, 125, doi:10.1029/2020JF005585. While in the Faroe Islands we have data from 1873. This will remain available for our users. SMB is the sum of snowfall and rainfall minus any evaporation or runoff. The vast section of Greenland stretches from Qaanaaq way up north to Upernavik on the coast down to Ilulissat in the Disko Bay. The top right map shows the difference between total 2020 melt days and the number of 1981 to 2010 average melt days from April 1 through October 31. Melting was intense in the northeastern section of the ice sheet, with 20 to 25 additional melt days than average, and moderately intense in the southwestern section of the ice sheet with 10 to 20 additional melt days (Figure 1). The top left map of the Greenland Ice Sheet shows the total number of surface melt days from January 1 through October 31, 2020. 14-07 is a guide on how to read and use of the climate data. So how did Greenland … Read about the data and other problems which occasionally occur in near-real-time data. Researchers also see evidence for ice flow rerouting and even abandonment of some glacier outlets. Learn about update delays. Climate-Data.org > Greenland > Nuuk. This reconfiguration of the ice sheet has important implications for other elements of the Greenland system, such as the flow of water beneath the ice sheet, and the movement of sediment and nutrients into the fjords. Annual Weather Averages in Nuuk. See our March 18, 2013 post for more discussion of melt calibration. We are working to improve the ice sheet mask. Temperatures are bitter cold in January, even in Ilulissat, which averages a low of 2 degrees Fahrenheit (16 degrees below 0 Celsius) to start the year. The model also estimated the total amount of melt that flowed off the ice sheet and into the ocean (Figure 5). On Thin Ice:Expedition to a Crumbling Ice Shelf. The top plot shows average air temperature as a difference from the 1981 to 2010 average at the 700 mb level, or about 10,000 feet above sea level, from June 1 through August 31, 2020. The new results show that during the Eemian period 130,000 to 115,000 years ago the climate in Greenland was around 8 degrees C warmer than today. (a) White and colored areas show the extent of the region where early ice flow maps (1985-1990) can be compared with images acquired up to 30 years later. Long temperature series shows a clear trend: We’re getting warmer. What both of these temperature curves show is that virtually all of the past 10,000 years has been warmer than the present. Cumulative degree days (the sum of the difference between the freezing point, 0 degrees Celsius, and the maximum temperature each day for the spring-summer melt season for two automatic weather stations in Greenland, at Nuuk (NUK_L) and Thule (THU_L). Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. Figure 3. While thinning ice and retreats from the ice edge change the ice sheet, the shape of the land beneath the ice remains mostly unchanged. Tedesco, M. and X. Fettweis. Greenland - Climate data - Climate information and average monthly temperature, humidity, rainfall, snowfall, daylight, sunshine, UV index, and sea temperature for all cities and towns. See About the Cryosphere. Scientists investigating how temperatures have changed prior to the invention of thermometers need to rely on a variety of climate “proxies”, which are correlated with temperature and can be used to infer, with some uncertainties, how it has changed in the past. The Daily Melt image (left) shows where the surface of the Greenland Ice Sheet showed melt on that day. Several recent high-melt years are shown for comparison. Polar Portal: Monitoring ice and climate in the Arctic Widespread thermometer measurements of temperatures only extend back to the mid-1700s. Credit: National Centers for Environmental Prediction (NCEP) Reanalysis data, National Center for Atmospheric ResearchHigh-resolution image, Figure 4. The top shows a graph of ice sheet surface temperature and altitude. In Greenland, an autonomous territory of the Kingdom of Denmark, the climate is arctic along the north-central coasts (zone 1 on the map), where the temperatures of the warmest months are around freezing (0 °C or 32 °F) and subarctic on the south-central coasts (zone 2 on the map), where the average temperatures in the summer months are above freezing, but still below 10 °C (50 °F). The total aerial extent of surface melting (total melt-day extent) through October 31 is slightly above the 1981 to 2010 average at 23.10 million square kilometers (8.92 million square miles) for 2020 versus 22.00 million square kilometers (8.49 million square miles) for the 1981 to 2010 average. In Nuuk, the capital, average winter temperatures are only −9 °C (16 °F). Daily melt extent mapping is suspended for the winter. Note that the northeast coast (northern Peary Land and Kronprince Christian Land) is showing erroneous melt pixels. Climate proxies can be obtained fromsources, such as tree rings, ice cores, fos… Though local surface winds can be quite high under certain conditions, air pressure patterns over the ice sheet indicated generally light regional winds that favored a westward to southwestward flow. Get daily satellite images and information about melting on the Greenland ice sheet. This site uses cookies to optimize functionality and give you the best possible experience.

This graph shows the cumulative melt day area for Greenland for 2020, 2019, 2018, and 2012, as well as the 1981 to 2010 average and typical ranges of cumulative melt day area. However, visitors may notice that the date on the image is occasionally more than one day behind. In Greenland the 1980 temperatures are about 1 deg C lower than in 1940 and since then there has been an increase of around 1.5 deg C. All part of the increasing temperature trend since LIA but not nearly as frightening as it would appear if one only looked at the records for the past 50 years. Greenland Ice Surface Temperatures, 2000-2014. This is his Fig 5: The Greenland melt images here are updated daily, with a one-day lag. Responses include narrowing of fast flow regions, rerouting of ice flow, and abandonment of some glacier outlets. Figure 5a. The Cryosphere, 14, 1209–1223, doi:10.5194/tc-14-1209-2020. Air off the far northern Atlantic Ocean in the Norwegian Sea swept in across the ice sheet. Get the Greenland weather forecast. Surface melting on the Greenland ice sheet ramped down at a near-normal pace in the weeks following the major melt event of early August (Figure 1). Credit: X. Fettweis, Université of Liège, Belgium/MARv3.11 regional climate modelHigh-resolution image, Figure 5b. Overall, melting on the Greenland ice sheet for 2019 was the seventh-highest since 1978, behind 2012, 2010, 2016, 2002, 2007, and 2011 (Figure 2). With a growing record of satellite imagery and advances in image processing, scientists are now able to better explore the changes to Greenland’s coastal area in the last three decades. There were two later melt events of note, on August 20 when extensive areas in northwestern Greenland melted totaling just over 20 percent of the ice sheet, and a late event on October 17, limited to the southwestern ice sheet totaling under 3 percent of the ice. This issue does not affect trends for the entire ice sheet. No. Net snow and rain input are shown in yellow, melt and evaporation loss in orange, and net surface balance in green. The Cumulative Melt Days image (right) shows the total number of days that melt occurred, year to date. 14-08 presents weatherdata for Greenland from 1958 to 2013. Climate data and weather averages in Nuuk. The balance between snow and rain input and melt runoff indicates a small net loss of ice this year. To pry climate clues out of the ice, scientists began to drill long cores out of the ice sheets in Greenland and Antarctica in the late 1960s. Scientists have estimated that the Greenland ice sheetis between 400,000 and 800,000 years old. This warmth coincided with the period known as the Medieval Climatic Anomaly, also known as the Medieval Warm Period, which we will discuss below. A modest beginning to the Greenland melt season, Greenland Surface Melt Interactive Extent Chart, Polar Portal: Monitoring ice and climate in the Arctic, Sea Ice Index (Passive microwave satellite data), MASIE (Daily sea ice extent, multi-source). Satellite sensor improvements, such as on Landsat 7 and 8, and improvements in image processing for ice flow mapping (see ITS_LIVE) have created an improved set of maps for documenting changes in Greenland’s ice outflow. A look at weather station data along Greenland’s west coast reflects the regional temperature trends (Figure 4). Thus, the 2020 total melt extent tracked at a level larger than about 75 percent of past years in the satellite record after late June.

Melt extent was greater than any year prior to 2002, with about 70 percent of the ice sheet experiencing some melting. It shows essentially the same temperatures as Cuffy and Clow (1997) but with somewhat greater detail. Much of the upper elevation areas of the ice sheet saw no melting this year. are found to be r=0.67 and r=0.60 for the periods 1785-1872 and 1873-1970 respectively. The mean temperature remains below +10° C (50° F) in June, July and August in just about every town in Greenland, whilst all places are below freezing from November through to April. Higher-than-average temperatures, with up to 3 degrees Celsius (5 degrees Fahrenheit) were limited to the far northern flank of the ice sheet, and significantly lower-than-average temperatures of 1.5 to 2 degrees Celsius (3 to 4 degrees Fahrenheit) near the Scoresby Sund in east-central Greenland.

Unprecedented atmospheric conditions (1948–2019) drive the 2019 exceptional melting season over the Greenland ice sheet. The 2020 season, which runs from September 1, 2019 to August 31, 2020 in this analysis, shows a net loss smaller than many recent years, but larger than most years in the previous century. Online tool for visualization and analysis. However, there is evidence that the settled areas were warmer than today, with large birch woodlands providing both timber and fuel. We will resume the daily image updates in April 2021. Throughout Greenland we find that temperatures in the last two decades are little different to the 1920s to 60s. Overall the pace of melt during the 2020 season was close to average until late June when a moderately prolonged period of above-average melt added to the cumulative total, bringing it to the upper part of the interquartile range (Figure 2). Our interactive chart supports a retrospective look at past Greenland melt seasons. Greenland Climate Greenland has two different climates and is dominated by ET. Read their blog ...
