National Solar Radiation Data Base (NSRDB)|太阳能数据集|气象数据数据集

The National Solar Radiation Data Base 1961-1990 (NSRDB) is a research product of the U.S. Department of Energy (DOE), National Renewable Energy Laboratory (NREL), Renewable Resource Data Center (RReDC). 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 database are listed at [http://rredc.nrel.gov/solar/pubs/NSRDB/1-1.html]. Version 1.0 of NSRDB (NSRDB) contains 30 years of solar radiation and supplementary meteorological data from 237 NWS sites in the United States, plus sites in Guam and Puerto Rico.

The updated 1991-2005 NSRD holds solar and meteorological data for 1,454 locations in the United States and its territories as well as a one-tenth-degree gridded data set that contains hourly solar records for 8 years (1998-2005) for the United States (except Alaska above 60 degree latitude) for about 100,000 pixel locations (at a nominal 10-km-by-10-km pixel size). In the updated NSRD, all gaps in station records were filled, and the stations were classified by data quality. The National Climatic Data Center (NCDC) provides primary distribution of the updated NSRDB, but the NREL site holds a solar research version of the NSRDB with additional solar fields (without meteorological data). About 40 stations in the updated NSRDB include measured solar data, supplied by the following agencies: Atmospheric Radiation Measurement (ARM) Program, DOE; Florida Solar Energy Center, State of Florida; Integrated Surface Irradiance Study (ISIS) and Surface Radiation Budget Measurement (SURFRAD) Networks, NOAA/ARL, NOAA/ESRL/Global Monitoring Division; Measurement and Instrumentation Data Center, NREL; University of Oregon Solar Radiation Monitoring Laboratory Network; and University of Texas Solar Energy Laboratory.

A significant difference between the 1961-1990 and 1991-2005 NSRDBs involves data storage. In the original, measured data were merged with modeled data such that a seamless data set of solar radiation values was produced. (The model essentially filled gaps in the measured data.) The update includes fields for both, which allows users the flexibility to choose modeled or, if available, measured data for an application.
