The Space Weather Prediction Center is one of the nine National Centers for Environmental Prediction (NCEP) and provides real-time monitoring and forecasting of solar and geophysical events, conducts research in solar-terrestrial physics (i.e. heliophysics), and develops techniques for forecasting solar and geophysical disturbances.

Global Map of Global Horizontal Radiation [5] Global Map of Direct Normal Radiation [5]. There are several measured types of solar irradiance. Total solar irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere.

Safecast is an international, volunteer-centered organization devoted to open citizen science for environmental monitoring.Safecast was established by Sean Bonner, Pieter Franken, and Joi Ito shortly after the Fukushima Daiichi nuclear disaster in Japan, following the TÅhoku earthquake on 11 March 2011 and manages a global open data network for ionizing radiation and air quality monitoring.
Each CERES instrument is a radiometer which has three channels – a shortwave (SW) channel to measure reflected sunlight in 0.2–5 μm region, a channel to measure Earth-emitted thermal radiation in the 8–12 μm "window" or "WN" region, and a Total channel to measure entire spectrum of outgoing Earth's radiation (>0.2 μm).

SOHO is a main source of near-real time solar data for both research and space weather prediction and inspired the STEREO mission. The Yohkoh spacecraft at LEO observed the Sun from 1991 to 2001 in the X-ray portion of the solar spectrum and was useful for both research and space weather prediction.
