I want to simulate the trend of soil salinity for about 50 years.
Due to the missing value of meteorological data, I have easily extracted the 50years-long sequence data of reference evapotranspiration (ET0,
underlying surface is near 12cm grass), precipitation, and LAI from the Google Earth Engine platform. I have obtained reference evapotranspiration data (ET0) from 50 years ago to the present, and the underlying surface is close to 12cm of grass.
But unfortunately, the long-term(50 years) sequence of PET is not obtained from the cloud platform, except MOD16 PET since 2000. In HYDRUS-1d， it is needed to input potential evapotranspiration (PET, sufficient water supply) and LAI to divide E and T. Could I use reference evapotranspiration (ET0) instead of PET as input?

I think you can. J
