USSR GTS Upper Air

Upper Air is historical digital data set DSI-6314, archived at the National Climatic Data Center (NCDC). This is meteorological upper air data. This is a historical upper air data set that was assembled by the old Union of Soviet Socialist Republics (USSR) from data they received from the Global Telecommunications System (GTS). Data is global for the period 1984-90. DSI-6314 was included in the larger Comprehensive Aerological Data Set (CARDS) Upper Air data set, DSI-6305, which was quality controlled as it was assembled from many smaller data sets. DSI-6314 itself was not quality controlled at the NCDC. Most users should not request DSI-6314, but should instead opt for DSI-6305. Major parameters in upper air data sets are: pressure, temperature, relative humidity, and wind speed and direction.
