Integrated Precipitable Water from GPS Observations and CIMEL Sunphotometer Measurements at CGO Belsk
Abstract This paper describes results of integrated precipitable water co-located measurements from two techniques: GPS solution and CIMEL-318 sunphotometer. Integrated Precipitable Water (IPW) is an important meteorological parameter and is derived from GPS tropospheric solutions for GPS station at...
