NSRDB: National Solar Radiation Database

NSRDB Webinar

Learn about the newest release of the National Solar Radiation Database (NSRDB)

The NSRDB (PSM V3) is a serially complete collection of meteorological and solar irradiance data sets. The data is publicly available at no cost to the user through https://nsrdb.nrel.gov . The dataset provides foundational information that underpins a large range of research activities that take place within the solar energy industry. The NSRDB data are used as input to performance and economic models to improve the accuracy of grid integration studies and facilitate energy modeling.

The NSRDB is continuously improved to represent the state-of-the-art in the science of satellite remote sensing of clouds and solar radiation. The recent deployment of the next-generation satellite GOES-16 (East) and GOES-17 (West) offered an opportunity to provide grid awareness at a higher temporal and spatial resolution. The current NSRDB provides data for the years 1998 to 2019 and comprises 30-minute solar and meteorological data for approximately 2 million pixels at a 4km x 4km resolution. For 2018 and 2019, the NSRDB also provides data at 5-minute temporal and 2 km x 2 km spatial resolution. The current NSRDB data includes multiple improvements since our last webinar in 2018.Typical Meteorological Year (TMY), Typical DNI Year (TDY) and Typical GHI Year (TDY) data sets are also included with each annual release. Additional products including spectral and ultraviolet (UV) datasets have been made available through the NSRDB.

This webinar will describe the current status of the NSRDB, including the datasets and distribution enhancements that have been made during the past two years. We will discuss our future plans and stakeholders attending the webinar can ask questions of the NSRDB team.
