Radiation calibration check
The calibration factors for the soil heat flux plates and the
radiometers were rechecked.
The soil heat flux plate factors entered in the calibration
table were in error. The factors entered in the logbook were
correct. The corrections were made to the calibration table.
The calibration factors for the radiometers was found to
be correct.

Conversion factors for sensible and latent heat fluxes.
Using the following values:
rho = air density = 1 kg per m cubed
Csubp = heat capacity = 1004.6 Joules per kg.degree
LsubH2O = latent ht of water = 2.5 E6 Joules per kg
For the sensible ht flux calculated in degrees centigrade . meters per second
multiple the given value X 1.01 E3 to obtain
energy flux in Watts per meter squared
For the latent ht flux calculated in grams H2O per kilogram . meters per second
multiple the given value X 2.5 E3 to obtain
energy flux in Watts per meter squared
