i want to validate the satellite soil moisture by the soil moisture from SWAT model. but how can cani make the spatial and temporal resolution of SWAT and any satellite time series soil moistire?
Maybe you have not necessarily made the same spatial resolution for the SWAT model and soil moisture data. The soil moisture output in SWAT is on the subwatershed and HRU scale, it is possible to calibrate the SWAT model on the subwatershed scale. To calculate the average value of soil moisture of a subwatershed and use this data to calibrate the relevant parameters in SWAT, maybe it is an alternative method.
