Dennis-I hope this e:mail works because lately nothing has gone out.
In response to your daily potential evapotranspiration (PET), this value
is calculated by CPC...it is not measured by the station. We take many
meteorological measurements (i.e. air and dewpoint temps, wind, cloud,
pressure) along with other calculated parameters (normal temp, stations
lat/lon, Relative Humidity (calculated), net radiation (calculated), and
some others). All I have in front of me now is the Fortran code and
an article we used to calculate this parameter. Unfortunately, we do
not have some nice 1-2 pages of documentation. Call or e:mail me if
you need more info, or forward the user to me.....David Miskus
Also....some US stations measured pan evaporation...but not PET.
