Sensitivity analysis in the technical potential assessment of onshore wind and ground solar photovoltaic power resources at regional scale - Supplementary material

We used a statistical linear model to infer MERRA’s wind speed v t (x ), at time t and on some ECMWF grid point x included in the MERRA grid point x , from MERRA’s estimate v t (x M ): v t (x ) = a E t v M t (x M ) + b E t , where the coefficients a E t and b x t are estimated using ECMWF’s wind speed estimate v E t (x ) as a response variable. This estimation is carried out adaptively on a monthly basis, from a sample whose size is defined by the ECMWF data temporal resolution (4 measurements per day x 30 days a month = 120 observations)
