[Equest-users] Estimating groundwater temps

Fri Mar 1 09:46:56 PST 2019

I did mean to cc the mailing list, I just failed to do so because I'm on my phone. Feel free to forward my message.

I got pretty used to reading fortran due to some side programs of E+, if you are indeed stuck I can help, just let me know
