I learned that NASA Ocean Color provides Rayleigh optical thickness for satellite sensors (VIIRS, SeaWiFS and MODIS) at different bands. My question is that is it possible to interpolate the Rayleigh optical thickness from a satellite altitude to an airborne sensor altitude, for example the CASI-1500 sensor with an altitude of 2 km? Or do you know how to calculate the Rayleigh optical thickness for the CASI-1500 sensor?
Code: Select all
scaleRayleigh = 1.0 - exp(-l1rec->alt / 10); // Assume 10km is e-folding height
Other groups have processed aircraft-based ocean radiometers (i.e. Naval Research Laboratory) and have developed data processors that can account for varying aircraft heights (e.g. TAFKAA, 6S). These may be more adaptable to your needs.
Thank you very much for your detail reply. It helps a lot.
