Calibrated solar resource of the 340 sub-prefectures (GHI, DNI, P50, P90)
For each sub-prefecture: annual and monthly GHI and DNI calibrated on ground measurements from reference stations, raw satellite GHI, inter-annual P50 and P90, calibration residuals and confidence level, diffuse fraction, humidex and daily variability.
P50 and P90 are inter-annual: they do not propagate model uncertainty and are not a bankable P90. The calibration (calage-guinee-v3) is documented in the repository doctrine.
