WebSurface Emissivity vs Reflectivity. Opaque (non-transparent) surfaces produce a combination of emitted and reflected radiation. Because the reflected radiation isn’t related to the surface temperature, we must tell the imager to disregard that portion of what it sees. To do that we correct for emissivity (E). Reflection (R) equals 1 minus E. WebRadiometric correction with Landsat 5 TM how much is the fica cap
