Retrieval of aerosol optical thickness from the relation between satellite imagery and ground data over farmland in Okhotsk area

[ABSTRACT] We present a method for retrieving aerosol optical thickness over the Okhotsk area based on ground data of a vegetation index for farmland monitoring. In the first step, we developed a camera for observation of the vegetation index. A NDVI value from the camera around the wheat canopy showed a good relation with SPAD, the chlorophyll content meter, in the same farmland. The NDVI value from ground data in west Abashiri farmland was 0.355(June 12, 2003). In the second step, we compare the ground data of NDVI and NDVI obtained from atmospherically corrected TERRA/MODIS imagery using 6S, the radiative transfer code (Channel 1 and channel 2, on June 12, 2003). Then the aerosol optical thickness value is 0.12 with the continental aerosol model and 0.07 with the maritime model. The methods appear to be useful to validate satellite remote sensing for non-regular atmospheric observation.
