Abstract :
Nowadays estimation methods by using remote sensing to approaching actual reality are come out one after the other even it is not easy to consider each of impact factors. In this paper using glob-cover land-cover map of Eastern Europe for the essential data, masking out the wetland distribution according classification. Then, in line with create 73 points interested in, through calculating snow coverage and LSWC (Land Surface Water Coverage) offset and onset timing and extension duration from AMSR-E database to find out the regular pattern of climate seasonal changes phenomenon. Thirdly, during comparing batch processing within pixel value in time series from 2003 to 2011, to find out the changes of snow and water coverage. Finally, combine with NDVI, precipitation and LST (land surface temperature) data to estimate the CH4 flux.
