| Abstract: | In this articles, the principles of the surface energy balance system(SEBS) and an arithmetic for quantitative sur- vey of surface drought characters based on SEBS using NOAA satellite images and observed weather data were introduced.The application of the arithmetic on drought monitoring at large scale in China was dicussed, including of data processing, model parameters initialization, results evaluation and error analysis. |

| Keywords: | remote sensing drought monitoring surface energy balance system relative evaporation drought characters |
