Research on variety characteristics of mainland China troposphere based on CMONOC

open access: yesGeodesy and Geodynamics, 2018
In this research, we processed the GPS and meteorological data from about 220 stations of Crustal Movement Observation Network of China (CMONOC) observed in 2014 and derived the Zenith Total Delay (ZTD) map in both spatial and temporal dimension.

Long-Term Trends of Astroclimatic Parameters above the Terskol Observatory

open access: yesAtmosphere, 2023
Astroclimatic conditions characterize the quality of an astronomical site. The Terskol Observatory was founded over 42 years ago in 1980. The astronomical site (coordinates 43°16′29″ N, 42°30′03″ E) is located about 10 km from Mt.

Analysis on Characteristics of Radiosonde Bias Using GPS Precipitable Water Vapor [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2010
As an observation instrument of the longest record of tropospheric water vapor, radiosonde data provide upper-air pressure (geopotential height), temperature, humidity and wind. However, the data have some well-known elements related to inaccuracy.
