How is 4LFTXsfc computed?
[Jun 1999] The Best Lifted Index is computed by finding the parcel with the warmest equivalent potential temperature. Then raising it to 500mb and subtracting its parcel temperature from the environment temperature. • How are SW radiative fluxes derived?[Jun 1999] The SW parameterization used is obtained from GFDL. The clear sky part is from Lacis and Hansen, 1974, JAS. The SW fluxes are broad band fluxes over the solar spectrum from 0.2-4.0 microns. • Is the concentration of CO2 constant throughout the reanalysis or is it changing according to some measurements? what is the concentration used? The model used has a constant 330 ppm CO2 concentration.
