Limb Transmittance

RFM Examples



Limb transmittance and optical thickness calculations (TRA = exp(-OPT)) for a tangent height 20 km viewing through the US Standard Atmosphere. Spectral range 12500–15000 cm-1 (800–667nm) sampled @0.01 cm-1, showing Oxygen A and B bands, with Rayleigh extinction slope.
