ESUN = SI = Exoatmospheric Solar Irradiance (W/m2)
Formosat 2:
Band 1 = 136,7
Band 2 =147,6
Band 3 =93,2
Band 4 =148,8
ALOS-AVNIR2
Band 1 =1959
Band 2=1851
Band 3=1546
Band 4=1061
Landsat 7
Band 1 =1969
Band 2 =1840
Band 3 =1551
Band 4=1044
Band 5 =225,700
Band 7 =82,07
Band 8 =1368
Digunakan untuk apa?
Konversi TOA Radiance ke TOA Reflectance (ρ)
ρ=(π*Lλ *d^2)/(Esunλ *cosθ)
dimana:
ρ = Unitless Planetary Reflectance
Lλ = Spectral Radiance at The Sensor’s Aperture
d2 = Earth-Sun Distance in Astronomical Units
ESUNλ = Mean Solar Exoatmospheric Irradiances
θ = Solar Zenith Angle in Degrees

selamat pagi pak. saya mau nanya, utk ESUN landsat 8 sesuai waktu akuisisi citra bisa didapatkan dimana ya pak? terimakasih sebelumnya pak
