What data can I get from the Solar Time Series Download tool?
From the Solar Time Series Download panel, a user can choose which dataset(s) to download and the type of data file they want. To learn more about each irradiance dataset, see their FAQ entries: Vaisala 1.0, Vaisala 1.1 Vaisala 1.2, Vaisala 2.0, Vaisala 2.1. Weather parameters are derived from NASA's MERRA-2 reanalysis dataset. More information on MERRA-2 can be found here. (This link will open in a new window.)
All datasets are updated monthly and deliver global horizontal (GHI), direct normal (DNI), and diffuse (DIF) irradiance, wind speed, wind direction, temperature, pressure, and atmospheric water vapor content parameters. Currently, time series data are available through the end of Mar 2021. NOTE: Since January 2020, NASA's monthly release of MERRA-2 data has been several days later than usual, delaying the Solar Time Series Tool update accordingly.
