The paper is devoted to processing of hydrophysical observations. Unfortunately, there may be errors in data even after calibration and validation made by information centers. Therefore, it is necessary to conduct an additional verification of the observations before using them in a range of hydrodynamics problems. In this work, the verification is conducted by an example of satellite sea surface temperature data (SST). An analysis of the Baltic SST observations was made with the identification of errors in the data on the basis of physical properties of the water area.
The method of additional verification of the satellite data is described. It is based on statistical approaches and allows one to set general features that are typical of the entire set of temperature field realizations. The results of this method applied to the real-time data are presented. Numerical experiments are conducted using statistical data on SST. Daily and monthly reanalysis data from the Copernicus marine environment monitoring service have been used in the calculations. The implemented method helps to solve the problem of the data verification by means of excluding the incorrect data fields.
Keywords: mathematical modeling, satellite observation data, data verification, sea surface temperature
