Dear All

Does anyone have a Penman-Monteith program ready for CRBASIC .

Many thanks

The help for the ETsz() instruction states that it implements the ASCE Standardised Reference Evapotranspiration equation. Looking this report up on ASCE's web site states that this model uses Penman-Montieth. It would seem to follow that this instruction uses Penman-Montieth.

Thank you very much. I had not noticed the presence of this instruction. Reading carefully who knows how many other instructions interesting, I can find!
