FIG WORKING WEEK 2017 29 may-2 June Helsinki Finland The main formula for calculating LST is, LST CALCULATION LST = TB10+ C1 (TB10-TB11) + C2 (TB10-TB11)² + CO + (C3+C4W) (1-ε) + (C5+C6W) A & Where: ⚫LST - Land Surface Temperature (K), W is values of atmospheric vapour content •CO to C6 - Split-Window Coefficient values (table; Skokovic et al, 2014 vide Rajeshwari, 2014) •TB10 and TB11 - brightness temperature of band 10 and band 11 (K) ⚫TB10 and TB11 can be calculated as TB = K2/Ln ((K1/ Lλ) +1) Where: • • K1 and K2 are thermal conversion constant and it varies for both TIR bands (table Skokovic) LA are Top of Atmospheric spectral radiance (m2*srad* μm). LA can be calculated as Lλ = ML*Qcal + AL Where: • ML - Band specific multiplicative rescaling factor (radiance_mult_band_10/11) = 0.000342 . Qcal value of band 10/11 image. • AL - Band specific additive rescaling factor (radiance_add_band_10/11) = 0.1 •ε - mean LSE of TIR bands. ε can be calculated as ε = (ε10 + ε11)/2NDVIV •A & Difference in LSE. A ε can be calculated as Aε = ε10- ε11 - •Where ε is LSE from band 10 and band 11 with formul ε = εs (1-FVC) + εv Where: * FVC • FVC is Fractional Vegetation Cover. For every band • FVC (NDVI NDVIS) /(NDVIv - NDVIS) NDVI = = ([B5]-[B2])/([B5]+[B2]), taken from raw data Landsat table ✓ NDVIS = ([B5]-[B4])/([B5]+[B4]), as above ✓ NDVIV = ([B5]-[B3])/([B5]+[B3]), as above
