RESUMO

The state of the atmosphere rating, weather and climate forecasting were actual for other areas of science and engineering. This paper deals with the development of methods for determining the tropospheric zenith delay (ZTD) from remote sensing data using GPS systems and of the experimental validation of proposed algorithm. The initial data were obtained by means of a regional system of high-precision satellite geodesic measurements in the Kharkiv region (NGCNET). Later they were used to calculate the zenith delay and weather parameters in each of the receiving points. The paper describes a technique for determining the hydrostatic and "wet" (ZWD) component of the tropospheric delay based on the data obtained by the twofrequency GPS receivers. A comparison between the data calculated from the known models, and received from NGCNET is performed. It is shown that the correlation coefficients between the values of the "wet" ingredients tropospheric delay is 0.5−0.6 for summer and 0.7−0.8 for winter and spring measurements. The correlation radii of ZWD values for different seasons are estimated in this paper.
