Soil salinity is a critical environmental problem especially in arid and semiarid regions. Then, the objective of this study is to detect saline soils by synergistic use of the Advanced Microwave Scanning Radiometer 2 (AMSR2) and the Moderate Resolution Imaging Spectroradiometer (MODIS) images. in this regard. the Total Precipitable Water (TPW) Vapor parameter obtained from AMSR2 and MODIS. the Microwave Polarization Difference index (MPDT), and a vertical to horizontal brightness temperature ratio (TBv/TBh) in the 6 GHz channel of AMSR2 were used in two procedures. in procedure 1. the thresholding on the TPW and MPDI, and in procedure 2. the thresholding on the TPW and the TBv/TBh in the 6 GHz channel were investigated. The overall accuracy and Kappa coefficient of the produced saline soil map by the procedure 1 were acquired as 0.865 and 0.715, and for the procedure 2 were 0.809 and 0.607, respectively.
