Abstract

The perturbed form of the radiative transfer equation (RTE) for the simultaneous retrieval of temperature and moisture is given in Smith et al. (1985, 1991) as where ΔR is the deviation of the observed radiance from a mean or initial guess radiance. The first integral term in (1) physically represents the contribution of the Planck equivalent departure of the ambient temperature from a mean or initial guess temperature, ΔB, weighted by the vertical derivative of transmittance dτ which is evaluated for the initial condition. Any contribution to ΔR due to differences between the initial and ambient transmittance profiles, Δτ, are accounted for by the second integral term.
