The modelling of radiation processes are essential to our understanding of the energy cycles between the land surface and the atmosphere. In addition to which they provide an important input to the planning of solar energy programmes.

Proba-1 charting Earth's radiation belts for a decade
07 November 2011
ESA's Proba-1 recently celebrated its tenth birthday in orbit. Kept busy as an Earth-observing mission, the microsatellite has also been building a detailed picture of changes in our planet’s radiation belts.
Smaller than a cubic metre, the technology-testing Proba-1 was launched on 22 October 2001. Among the payloads was ESA’s SREM standard radiation environment monitor, which was turned on a week later.
