Comparison of calculated and measured values of total and diffuse radiation received on the inclined surface according to observations in the MO MSU
The article contains the results of the comparison of measurements of total and diffuse radiation on an inclined surface in Meteorological Observatory of Moscow state University for the period from IX 2014 to X 2015, calculated by three models - isotropic and two anisotropic. It is compared here the average daily and hourly amounts of radiation for all sky conditions, overcast and clear sky. It is concluded that underestimation of daily sums of total radiation when using the isotropic model, and the overestimation when using anisotropic Klucher and Hay models.
