The Environmental Working Group (EWG) was established in June 1995 under the framework of the U.S.-Russian Joint Commission on Economic and Technological Cooperation. The EWG's objective was to explore how the United States and Russia could exchange unclassified data derived from each country's national security collection systems. In January 1996, the EWG Arctic Climatology Project took on the task of compiling digital data on arctic regions to expand scientific understanding of the Arctic. The EWG decided to develop a set of three complementary atlases on CD-ROM for arctic oceanography, sea ice, and meteorology.
The Arctic Meteorology and Climate Atlas was developed by specialists from the Arctic and Antarctic Research Institute (AARI), St. Petersburg, Russia; the University of Washington, Seattle; and the National Snow and Ice Data Center, University of Colorado, Boulder. The Atlas contains three main sections: a history section, a primer, and a data section. The history section and primer provide background and introductory information for newcomers to arctic meteorology, while the data section contains gridded fields of meteorological parameters and newly released meteorological station data from Russian and other sources. In addition, the Atlas includes several English translations of Russian technical documents and a glossary of meteorological terms in English and Russian.
This documentation is an overview of the Atlas and was prepared by NSIDC based on the complete documentation available on the Atlas CD-ROM.
Note: This online documentation includes an important Addendum and Errata section that is not included in the CD-ROM's documentation.
NSIDC requests that users acknowledge use of the EWG Joint U.S.-Russian Sea Ice Atlas, thereby recognizing its funding agencies and broadening awareness of its services. Citations in reference lists accompanying published work should state:

The Arctic Meteorology and Climate Atlas was developed by specialists from the Arctic and Antarctic Research Institute (AARI), St. Petersburg, Russia; the University of Washington, Seattle; and the National Snow and Ice Data Center, University of Colorado, Boulder, USA. The Atlas has three main sections.
Arctic and Antarctic Research Institute
National Snow and Ice Data Center
Two-meter air temperature: Monthly means, standard deviation, and coefficient of variation for the 1980s and 1990s.
Sea level pressure: Decadal monthly means for the 1950s through 1990s; period-of-record monthly means for 1951 through 1990; long-term monthly means for 1961 through 1990; and fields of anomaly, standard deviation, and coefficient of variation.
Precipitation: Monthly mean fields for the period 1951 to 1990 in millimeters (averaged over the month).
Cloud: Decadal monthly mean fields of total and low cloud cover for 1952 through 1995; long-term monthly mean fields of total and low cloud cover for 1952 through 1995.
Snow: Monthly mean snow depth fields on land for 1966 through 1982; monthly mean snow depth fields for the Arctic ocean for 1954 through 1991; monthly mean snow water equivalent fields for the Arctic ocean for 1954 through 1991.
Global solar radiation: Climatological monthly means. In addition, the "Gridded Fields" section of the Atlas contains a climatology of direct, global and net radiation from Russian and other sources, compiled and scanned at AARI by M. S. Marshunova.
Monthly means of meteorological observation data from 65 Russian and 24 western coastal and island stations for a period that includes the early 1950's through 1990 are provided. The Russian station observations include two-meter air temperature, sea level pressure, total and low cloud amount, and relative humidity. The western station observations include sea level pressure, two-meter air temperature, and precipitation. After 1960, a moisture parameter (relative humidity or dew point temperature) is generally available.
The data in this section of the Atlas, taken together, provide observations with better spatial and temporal coverage of the Arctic ocean than has generally been available in the past. These data are three or six hourly synoptic data, monthly means, or in the case of DARMS, once daily observations.
Data are from:
Russian "North Pole" drifting stations: Two-meter air temperature, sea level pressure, total and low cloud, surface temperature, and wind velocity, for years spanning 1938 to 1991.
Western drifting stations: The earliest data are from the Fram in 1893, and the latest are from the AIDJEX experiment in 1975 and 1976. Parameters vary but all stations include two-meter air temperature, surface air pressure, wind speed and direction, and humidity data. Note that oceanographic data from certain Western drifting stations may be found in the National Oceanic Data Center's World Ocean Database.
Russian Drifting Automatic Radiometeorological Stations (DARMS): Wind speed and direction, surface air pressure and air temperature from 1958 through 1975.
Russian Ice Patrol ships: Wind speed and direction, air pressure, air temperature, sea surface temperature, total cloud amount, low cloud amount, and relative humidity for voyages from 1952 through 1982.
