NASA Remote Sensing Validation Data:
Saudi Arabia
Format of the Data Files
The Saudi solar resource data files are comma separated values ASCII files. Table 1 below lists the Annex II data elements in order, while Table 2 lists the BSRN data elements. Included in both tables are corresponding measurement units and hot links to solar radiation resource term definitions.
