RFM Flags: Calculate Brightness Temperature Spectra | 08MAR24 |
T = c_{2} ν / ln ( 1 + c_{1} ν^{3} / R )where c_{1}, c_{2} are the radiation constants, approx 1.191E-3 nW/(cm^{2} sr (cm^{-1})^{4}) and 1.439 K/cm^{-1} respectively (actual values in phycon_dat.f90), ν is the wavenumber [cm^{-1}], R is the radiance [nW/(cm^{2} sr cm^{-1})].
