Abstract

In this work, we present estimates of the predictions of global horizontal irradiance, as well as of the profiles of air temperature and relative humidity in the interval of 10-40 m under the clear-sky summer conditions near Tomsk. The numerical experiments are carried out for three different configurations of the WRF-Solar model. Data of measurements are obtained using the measurement complex, located on the territory of “Fonovaya” observatory (IAO SB RAS). The statistical analysis of the calculation errors showed that the mean absolute errors and the root-mean-square errors are: 30 W/m2 and 40 W/m2 for GHI, 1.2°C and 1.5°C for air temperature, as well as 10% and 15% for the relative air humidity, averaged over the altitude interval of 10-40 m. Preliminary results showed that the chosen sets of parameterizations make it possible to simulate these characteristics with the accuracy no worse than that of similar calculations by other authors under the analogous conditions.
