Abstract

Abstract

The water vapor amount is simulated through its statistical relation to the ratios of reflectance in several channels, which are selected and grouped from the 940 nm weak water vapor absorption band and the vicinal window region. The simulation results of water vapor amount have an average relative error of 6% by compared with the independent radiosonde observation.
- Satellite remote sensing;
- Water vapor amount;
