Upper-air climate monitoring: data sources, technological aspects, and some results

[摘要] Monitoring and analysis of upper-air climate variations are performed regularly at the Russian Research Institute for Hydrometeorological Information - World Data Center (RIHMI-WDC). This paper describes a data source for upper-air climate monitoring that is based on radiosonde observations from a global network and further steps in space-time generalization of original temperature and wind observational data for the troposphere and the lower stratosphere. Technological elements of monitoring of these climate parameters are described. A comparison of the RIHMI-WDC time series with those from other independent sources demonstrates good agreement between them. Some features of recent tropospheric and lower stratospheric climate variations for 2015, 2016, and 2017 temperature and for 2017 wind parameters are shown and discussed.
