Inter-Calibration Of Satellite Passive Microwave Land Observations From Mwri And Amsr-E Over The Bare Soil And Grassland

Evaluating and calibrating MWRI Tb record based on AMSR-E Tb record are very meaningful since these two sensors have similar configurations and the majority of geophysical algorithms have been developed based on AMSR-E Tb record. While previous studies are focus on the ocean and polar region ice sheet, this study aimed to evaluate and calibrate MWRI Tb record over bare soil and grassland and analyze the effects of these two land cover types on Tb record quality. The results show that the quality of MWRI Tb record over bare soil performance better than that over grassland and the quality at different frequency over bare soil is more stable than that over grassland. In summary, grassland had more significantly effects on MWRI Tb record than bare soil.
