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 sporadic solar contribution during some large solar energetic particle events is evaluated using the SiGLERT model, which has been developed and is maintained at Paris Observatory. The galactic contribution is computed with CARI-7 and CARI-7A software of the FAA (US Federal Aviation Administration). Daily maps at various altitudes, updated every 3 minutes in case of a significant solar event, are displayed here.
