Solar Irradiation Data Sources

From Appropedia

This page is being created by Alex Hirzel and his research group at Michigan Tech to catalog publicly-available sources of solar irradiance data.

Goals for this page[edit]

Measured solar irradiation data is used in forecasting research. This page aims to provide a list of data sources and a summary of each. For now, we are focused on high-resolution (one hour or finer) data.

Main list[edit]

Name Country Area Resolution Format Method Notes
NSRDB USA maps of sites: 1961-1990, 1991-2010 1 hour Downloadable `.csv`  ? "The National Solar Radiation Data Base 1961-1990 (NSRDB) contains 30 years of solar radiation and supplementary meteorological data from 237 NWS sites in the U.S., plus sites in Guam and Puerto Rico." Also: manual1990 manual2010
USCRN country area resolution format method notes
CONFRRM USA map
NREL MIDC USA map list  ?  ? method notes
WRDC worldwide (many countries) map hourly, daily tabulated HTML (values don't seem to be W/m^2?) data here
UTE (Uruguay national electric company) Uruguay  ? 10 minute probably not publicly available Kipp & Zonen CMP6 pyranometers, described in Section 3.2 of this paper
CNE-GTZ (Spanish) Chile Pozo Almonte monthly mean, daily sum, and one randomly-chosen day at 1 hour resolution  ? Kipp & Zonnen CMP11 pyranometers referenced in this paper, see Figure 3
National Solarimetric Archive (link? I can't read Spanish) Chile several (sporadic) monthly mean and one typical clear sky day at 1 hour resolution  ?  ? stations operated for various time periods, 2 to 21 years, calibration/uncertainty information is unavailable referenced in this paper, see Table 1
Dirección Meteorológica de Chile (Spanish) Chile several (sporadic) 10 minute excel spreadsheet pyranometer publically available, small fee covers processing costs. referenced in this paper, see Table 2
paper?? Bolivia, Ecuador, Brazil, China, India, Nepal, Iceland, Japan  ?  ?  ? see Japanese references This paper references observations made/published by a Japanese team. Looks like good data behind a language barrier. May be able to email authors for data.
