Retrieval of Atmospheric Water Vapor Using MODIS Near Infrared Channel Data in Guizhou Plateau
基于MODIS近红外数据的贵州高原大气水汽反演研究

Precipitable Water Vapor(PWV) derived from the ratio of the apparent reflectance values of the 18th and 19th bands of Moderate Resolution Imaging Spectrum-radiometer(MODIS) is introduced.The relation of the ratio and the PWV value lies in the formula set up by MODTRAN simulation.Comparing with EOS PWV products and local radiosonde data in the Guizhou Province which is considered as the true PWV value,the results show that the method could be applied under the condition of cloudless(PWV <7 cm),and the retrie...
