Issues

• CRTM-Exp cloud optics: released CloudCoeff_Exp_Full6.nc has no Reff_to_Dm, and the liquid factor is inconsistent with the table's Dm axis

• FASTEM reflection correction is evaluated at the vertical transmittance; the regression expects the slant one

• AOD Skip_Profile fix (#372) is missing from v3.2.0: CRTM_AOD_TL/AD/K fail on a flagged profile (regression vs v3.1.6)

• Aerosol backscatter TL/AD inconsistent with the forward model: TL counts it twice, TL/AD ignore the scattering gate, GOCART-GEOS5 AD propagates kb twice (v3.1.3 - v3.1.6)

• Active-sensor (radar) TL/AD use the vertical optical depth while the forward model uses the slant path: attenuated-reflectivity Jacobians wrong off-nadir (v3.1.1 - v3.1.6)

• IR cloud phase coefficients read one Legendre order low since v3.1.0 (pcoeff_IR allocated 1-based); IR/VIS/UV cloudy radiances off by up to ~8 K
