Hi,

I want to find a multiple linear regression to predict and produce a time series of actual evapotranspiration, ET (response variable) using remotely sensed time series of land surface temperature and ground-observed air temperature (explanatory variable) data. All data are raster (.tif) format. They are 5-year dataset with the same extent and temporal (16days) and spatial (500m by 500m) resolution.

I was trying to some ways after looking into the community posts relative to spatial regression, raster regression, spatial statistics, etc. but I fail to get the result that I one. Most of them I found didn't address the time series of two different explanatory variable at the same time.

Can anyone help me out to get an idea?

Any chance you got anywhere with this? I’ve tried and failed with the generate trend tool and am searching for an OLS type raster method as well
