Paper Abstract

It is necessary to perform atmospheric correction for extracting quantitative information from Moderate Resolution Imaging Spectroradimeter (MODIS). In this paper, a feasible method which atmospheric correction of MODIS image was performed by using meteorological data was discussed. The reflectance of two bands was obtained from MODIS and the approach based on Dark Object Subtraction (DOS) method was used to calculate the path radiance with the reasonable dark-object reflectance choice. The atmospheric transmittance can be derived from the atmospheric parameters at overpass time of satellite by using interpolation among local meteorological records. At last the reflectance of objects was obtained. This approach was evaluated by comparing the normalized difference vegetation index (NDVI) in close date before and after atmospheric correction of MODIS, and by using single day MOD09. Results showed that NDVI by using this approach is close to truly data. It will be feasible to use meteorological visibility and vapor pressure data to perform atmospheric correction of MODIS data.
