The National Solar Radiation Data Base (1961-1990) from the National Renewable Energy Laboratory (NREL) via WWWEntry ID: NREL_NCDC_NSRDB_WWW
Abstract: The NSRDB is a serially complete collection of hourly values of the
three most common measurements of solar radiation (global horizontal,
direct normal, and diffuse horizontal) over a period of time adequate
to establish means and extremes, and at a sufficient number of
locations to represent regional solar radiation climates. The solar
radiation and meteorological elements contained in the data ... base are
listed in Table 1-1.
National and international meteorological practices (WMO 1967) call
for the use of a 30-year period of record to establish normals, means,
and extremes for meteorological variables. Because the National
Oceanic and Atmospheric Administration (NOAA) updates the normals,
means, and extremes for the United States each decade, the period from
January 1961 through December 1990 was used for the NSRDB.
Standard International (SI) units are used for all elements in the
data base except atmospheric pressure. Atmospheric pressure is
reported in millibars because these units are commonly used in
computer models to estimate solar radiation and are consistent with
standard NWS reporting practices. Appendix A contains factors to
convert all elements to other commonly used units.
All data are referenced to local standard time. The solar radiation
elements are the radiant energy integrated over the hour preceding the
designated time. Meteorological elements are the values observed at
the designated time.
When a station contains only modeled solar radiation data, it is
referred to as a Secondary station. Primary stations contain measured
solar radiation data for at least a portion of the 30-year record. The
NSRDB contains a total of 56 Primary and 183 Secondary stations. Their
locations are shown in Figure 1-1. Primary stations are listed in
Table 1-2 and Secondary stations are in Table 1-3. The Weather Bureau
Army Navy (WBAN) numbers used to identify the stations are given in
these tables. Appendix B provides more comprehensive information about
each of the stations incorporated into the data base.
