Hi all,

We have a weather station near the Amboseli National Park in Kenya. It calculates ETo from data collected from its onboard sensors. I obtained the same data from WAPOR database and I was stricken to see a very similar pattern and quite a regular offset. I attach the plotted data to give you an idea.

Do you have suggestions on how to calibrate the RS data? Would be great to be directed to some practical how-to document.

Thanks a lot in advance,

Francesco
