| Popis: | The brightness temperature of the surface-air system can be determined from the METEOSAT IR window, but the surface temperature cannot be established directly. Therefore a radiative transfer model based on radiosonde data was used to estimate the atmospheric correction. Comparing the longwave radiances, which are calculated by the model and received by the satellite, the surface temperature can be determined. For the determination of surface temperature to large area the bi-harmonic spline interpolation of radiosonde data was resolved to projection grid. |
