Climatic conditions over the territory
of Russia.

RIHMI-WDC regularly updates series of temperatures in free atmosphere (troposphere and lower stratosphere)obtained from radiosonde data. The CARDC data set is used to obtain data series observation period 1958-1998. The AEROSTAB data set (uper-air observations obtained through communication channels) is used to update data series with current data. The next monthly data portion due is processed and the data series are updated on approximately the 20th of each subsequent month.

Fig. 2. Monthly global temperature anomalies in troposphere (850 - 300 hPa) for the period January 1958 - December 2000 from RIHMI-WDC's data. Basic period: January 1961 - December 1975.
