The original exponential factor (0.75) was put back into the relationship used to calculate longwave emissivities from cloud optical depths. This change should have been made along with the other changes on 2004/11/20/12 when reverting back to operational values for cloud calculating cloud optical depths. Prior to this change the solar absorption by clouds was made to be the same as in the EtaZ parallel, but the longwave emissivities were (inadvertently) larger than what's parameterized in operations.
