A system to distribute satellite incident solar radiation in real-time

A long-term Global LAnd Surface Satellite (GLASS) data-set for environmental studies

“…The daily estimates have an average RMSE of 29.16 W m (2 (17.7%) under all-sky conditions, which is relatively comparable to the results of other studies on using GMS-5 (Tanahashi et al 2001;Kawai and Kawamura 2005) The GLASS insolation algorithm is almost identical to that discussed in Section 4.2 with a few differences, and the preliminary validation results are very encouraging. Zhang et al (2013) validated the instantaneous insolation product using ground measurements at eight sites (two SURFRAD sites, three AERONET sites, one CarbonEuropeIP site, and two sites in China), the overall R 2 , bias, and RMSE is 0.87, 7.5 W m (2 , and 103.6 W m (2 , respectively.…”

Validation and Improvement of Satellite-Derived Surface Solar Radiation over the Northwestern Pacific Ocean

“…Summary of the Model to Derive the Downward Surface Short-Wave Radiation The model used to derive DSSR in this study is briefly explained here. More detailed explanations can be found in Kawamura et al (1998) and Tanahashi et al (2001). In this model, the surface solar radiation under the cloudless sky, S C , is expressed as the sum of the following three components (Paltridge and Platt, 1976;Iqbal, 1983;Kizu, 1995 where S I is the direct irradiance, S R the diffuse irradiance due to Rayleigh scattering, S A the diffuse irradiance due to scattering by aerosols, and S the solar radiation at the top of the atmosphere.…”

“…The coefficient a was 1.2 in his study. Tanahashi et al (2001) improved the attenuation coefficient, which was dependent on A sat and the brightness temperature of the infrared-1 channel (Table 2). They calculated the values of the coefficient from Eq.…”

“…The hourly DSSR in Japan was about 32%; the model overestimated the hourly value by about 30 W/m 2 . Tanahashi et al (2001) improved the cloud attenuation coefficient in the Kizu model using land in situ DSSR data. Kawamura et al (1998) Kawamura et al, 1998).…”
