Abstract:

The comparison of data on the moisture content of the troposphere obtained from GPS satellite monitoring, radiosondes, and water vapor radiometer measurements at permanent observation points IRKM (Irkutsk, 52°13¢ N, 104°19¢ E, h = 511 m) and BADG (Badary, 51°46¢ N, 102°14¢ E, h = 838 m) is presented. Values of the total zenith tropospheric delay for the BADG observation point derived from processing of the primary GPS data with the GAMIT and Bernese software packages are compared. Time series of tropospheric moisture content for the IRKM station derived from GPS observations and radio soundings and for the BADG station found from GPS observations and water vapor radiometer measurements during 2020 are analyzed and compared. The use of the GPS method for monitoring the moisture content of the troposphere at the network being created in the Baikal region has been substantiated.
