LST (Land Surface Temperature; Atitar and Sobrino, 2009)

 

LST is estimated for day- and night-time acquisitions using the method developed by Atitar and Sobrino (2009):

 

 

where T108 and T120 are brightness temperatures for MSG bands Ir108 and Ir120 respectively, ε and Δε are respectively the average emissivity and the spectral emissivity difference for these bands, W is the total amount of water vapor, and θ is the observation zenith angle.
