Validation HC3v4 and HC3v5 Archives - BSRN stations

Last update: Oct. 2019

CURRENT STATISTICS

Validation of HC3v4 and HC3v5 Archives (2004 - J-1) against the measurements of 21 BSRN stations

 

 

Date of the validation: May 2019
Network: Baseline Surface Radiation Network (BSRN). See whole list of BSRN stations.
Number of stations: 21 (see Table 1), located in the Meteosat Second Generation Prime satellite.
Original time step and radiation components: 1 min GHI and DNI
Author: Laurent Saboret, TRANSVALOR
Publication: -
Have a look to previous validation results (14 BSRN stations only and computed over a shorter period of time).
