In the course of solving the problems on the study of the synoptic atmospheric processes a significant amount of passive microwave satellite data was accumulated and processed with the help of satellite radiothermovision techniques. In particular, integral series of global fields of total precipitable water and other geophysical parameters on a 0.25° grid with a time step of 3 hours within continuous interval of observations from year 2004 through year 2015 were constructed with the use of the interpolation scheme of satellite radiothermovision. Further application of interactive interpolation procedure allows assessing the instantaneous states of geophysical fields of the Earth's atmosphere at arbitrary times. The results of the approach can be widely used in visualizing and studying the dynamics of mesoscale and synoptic atmospheric processes, working out and implementation of calibration and cross-calibration procedures of new satellite products, efficient co-processing with heterogeneous data from other sources, requiring higher synchronization of the retrieved parameters. The recently created geoportal of satellite radiothermovision aims to provide collective use (including remote processing) of the accumulated information. The paper describes the formats of the distributed products, and the implemented and planned network services; and also discusses some promising directions of the geoportal development.
Keywords: satellite radiothermovision, geoportal, dynamics of geophysical fields, network services
