Abstract This paper describes in brief the development of the MPI (Microwave Polarization Index) technology and makes a derivation for MPI according to the radiance transfer equation. The authors collected MODIS LAI/NDVI matching to AMSR-E MPI by using the longitude/latitude as the control condition. The analysis indicates that there exists an exponent relationship between MPI and LAI/NDVI. The better the relationship, the lower the frequency. This paper also deals with the microwave polarization index in the application field.
