I am trying to create a model in ArcGIS that makes use of a DEM and other user-input parameters in order to calculate the evapotranspiration at a hydrological basin. To be exact, the final output of the whole process will be a raster that instead of height value will have evapotranspiration values at every pixel. The problem that I have come up with is that I extract the XYZ values in respective attribute fields for multiple points in a shapefile, and then I want to define several equations that make use of the 3D coordinates to calculate other parameters. I dug a bit in the internet but I still haven't found an answer to this problem. The second thing I want to ask is how is it possible to create some user input dialogs so as to incorporate other non-spatial parameters like temperature or air humidity. I hope I made myself clear enough.
Looking forward to your answers!
P.S. I can attach a screenshot of the part of the model I have created so far upon request.
