Abstract:
Peoples Republic of China Upper Air is historical digital data set DSI-6315, archived at the National Climatic Data Center (NCDC). This is meteorological upper air data. This is a historical data set of upper air data for the Peoples Republic of China that was assembled by that nation. Data is for the period 1957-90, although the period of record varies by station. DSI-6315 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-6315 itself was not quality controlled at the NCDC. Most users should not request DSI-6315, but should instead opt for DSI-6305. Major parameters in upper air data sets are: pressure, temperature, relative humidity, and wind speed and direction.
