The map and bar graph show how air temperatures in the Arctic compare to averages from 1979 to 2015. Overland, et al., (2004), Seasonal and regional variation of pan-Arctic surface air temperature over the instrumental record. Although there are year-to-year and regional differences in air temperatures due to natural variability, the magnitude and Arctic-wide character of the long-term temperature increase is a major indicator of global warming and the influence of increases in Greenhouse gases (Overland, 2009; Notz and Stroeve, 2016). On the map, areas with higher than average temperatures for the selected month and year are indicated in oranges and reds (positive anomalies), and areas with lower than average temperatures are shown in blues (negative anomalies). Surface Air Temperature Research by the International Arctic Buoy Programme (IABP) and the NASA EOS program Polar Exchange at the Sea Surface (POLES) Variations in Surface Air Temperature Observations in the Arctic, 1979 - 1997 Ignatius Rigor 1, Roger L. Colony 2, and Seelye Martin 3 1 Polar Science Center, Applied Physics Laboratory, University of Washington, … The map and bar graph show how air temperatures in the Arctic compare to averages from 1979 to 2015. Climate, 17, 3263-3282. Arctic Data Sets from the Polar Science Center at University of Washington/Applied Physics Laboratory ; Historical data from the First International Polar Year, 1881-1884 from NOAA ; Freshwater Switchyard of the Arctic Ocean - from the University of Washington Polar Science Center Individual years from 1958-2019 are shown by the sequential blue/purple to yellow lines. The average April global air temperature was +1.16C above the 1951-1980 climate baseline. J. Retrospective or Historical Data, Analyses and Indices Data and Analyses. Arctic long meteorological data series. [Click this link to see the Spring temperature … Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v4 (meteorological stations) and ERSST v5 (ocean areas), combined as described in our publications Hansen et al. CRU Air Temperature and Combined Air Temperature/Marine Anomalies V4 : Global … On the map, areas with higher than average temperatures for the selected month and year are indicated in oranges and reds (positive anomalies), and areas with lower than average temperatures are shown in blues (negative anomalies). Annual values were calculated from monthly average temperatures. 2020 is indicated by the red line. The GISS Surface Temperature Analysis (GISTEMP v4) is an estimate of global surface temperature change.
Arctic air temperature is an indicator of regional and global climate change. Those include: NOAA Next Generation Radar (NEXRAD) Products Severe Weather Data Inventory (SWDI) State of the Climate Monthly Overview – National Snow and Ice U.S. 15 Minute Precipitation Data U.S. Arctic Basin transect: 76 2.119N 157 55.807 W to 80 28.254 N 7 34.4 E: Time Period: 12 Aug – 26 Sept 2005: Parameters: Snow depth, ice thickness, light transmission,soot content, incident solar irradiance, spectral reflectance, surface temperature, ice watch, aerial photographs, mass balance: Data Access: Contact Don Perovich *Surface air temperatures in the Arctic continued to warm at twice the rate relative to the rest of the globe. IABP CD-ROM. Daily 2 m surface air temperature for the Arctic averaged above 80°N. ERA40 has been applied for the 1958-2002 climatology (white line), … Data. Long Arctic surface annual air temperature series: Fairbanks (Alaska), Nuuk (Greenland), Akureyri (Iceland), Svalbard (Norway), Ostrov Dikson (Siberia), and Hatanga (Siberia). Arctic surface air temperature is an indicator of regional and global climate change. CRU Air Temperature and Combined Air Temperature/Marine Anomalies V4 Global gridded (5°x5°) monthly anomalies of observed air temperature and combined observed air and marine temperature ( HADCRU4 ) from the mid 1800's to near present.Current version is V4.2.0 which was put out 5/9/2013. Although there are year-to-year and regional differences in air temperatures due to natural variability, the magnitude and Arctic-wide character of the long-term temperature increase is a major indicator of global warming and the influence of increases in greenhouse gases (Overland, 2009; Notz and Stroeve, 2016).
