RADIATION ENVIRONMENT (from CRATERRE)

This image provides an overview of space environment : top panel = solar protons measured by GOES, the second panel from to = Kp magnetic activity index and next three panels = electrons (differential omnidirectional 1.6 MeV) and protons ( integral omnidirectional > 97 MeV and differential omnidirectional 27 MeV) in a L versus time plot along JASON3 orbit.

COSMIC RAYS: DOSE RATES IN THE ATMOSPHERE (CERCLe)

The 3Soleil/CERCLe observing service at Paris Observatory (Meudon) produces maps of radiation dose rates in the Earth's atmosphere for the needs of civil aviation. The radiation is produced by galactic and solar cosmic rays. The galactic contribution is evaluated in cooperation with the French Institute for Radioprotection and Nuclear Safety (IRSN), based on the EPCARD software of Helmholtz Zentrum (Munich). The sporadic solar contribution during some large solar energetic particle events is evaluated using the SiGLE model, which has been developed and is maintained at Paris Observatory. Daily maps, updated every 5 minutes in case of a significant solar event, are displayed here.
