National Solar Radiation Data Base

1991- 2005 Update

  NSRDB Errata (NREL solar files)

  • 2007-05-16 - Data set released

  • 2007-05-24 - Corrected improper field assignments for precipitable water, ozone, and albedo.
    Also removed a space in the date (day) field for day of month less than 10.

  • Manual: in Table 3 (section 1.4.2) has uncertainty and source flags for radiation fields switched (header in the files is correct)

  • Cloud cover fields have missing data as -990 rather than -9900

  • Manual: in section 1.3.2 mentions 15-year summary files for the Hourly Statistics Files. No such files exist. Only annual files exist for the DSF product.
