| description | Meteosat Second Generation (MSG) satellite images acquired every 15 min
during daytime are currently processed by the Heliosat-2 method every night
to generate the HelioClim-3 (HC3) database of the surface solar irradiation
for the day before. A new service is proposed based on version 4 of HC3
(HC3v4) that offers real-time and forecasted irradiation for horizons up to
a few hours. The service is based on a local persistence of the clear-sky
index. Its results were compared to coincident high quality 15 min global
irradiations measured in fourteen stations belonging to the Baseline Surface
Radiation Network (BSRN). For forecasts for a temporal horizon of 15 min
ahead, the relative bias and root mean square error (RMSE) range
respectively from 0 to 2 %, and 20 to 23 % for most stations. The
correlation coefficient ranges from 0.94 to 0.95. These performances are
similar to HC3v4 for the same stations. Expectedly, the quality of the
forecasts degrades as the temporal horizon increases. For 1 h ahead
forecasts of 15 min irradiation, the relative bias, root mean square error
(RMSE) and correlation coefficient range respectively from −3 to 1 %,
30 to 37 %, and 0.90 to 0.91. |
