Abstract
Abstract An attempt is made to resolve the difference in Nimbus II satellite-observed and calculated atmospheric radiances in the 6.7-μm water vapor band. Regression equations were calculated to relate the Nimbus II MRIR (medium resolution infrared radiometer) water vapor channel radiance measurements to radiances calculated assuming different values of the effective water vapor absorption coefficient. A value of log10L*=2.4, where L* is the effective water vapor channel absorption coefficient, produced the maximum correlation between computed and observed values. The regression equation for this water vapor absorption co-efficient may be used to recalibrate the Nimbus II 6.7-μm radiance observations. The radiance upwelling from the atmosphere in the 6.4–6.9 μm spectral region (the 6.7- μm channel of Nimbus II) arises mainly from the 200–600 mb atmospheric layer. However, assuming that the water vapor profile can be represented by a power function, the entire water vapor distribution can be estimated from...
