Baseline Surface Radiation Network (BSRN) is a project of the World Climate Research Programme (WCRP) and the Global Energy and Water Cycle Experiment and as such is aimed detecting important changes in the Earth's radiation field at the Earth's surface which may be related to climate changes.
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.
Satellite image of the reactor and surrounding area in April 2009. The Chernobyl Nuclear Power Plant Zone of Alienation, [a] also called the 30-Kilometre Zone or simply The Zone, [5]: p.2–5 [b] was established shortly after the 1986 Chernobyl disaster in the Ukrainian SSR of the Soviet Union.
Map of contaminated areas around the plant (22 March – 3 April). Map of detected radioactivity as of April 2011 Map of detected radioactivity as of March 2012 Fukushima dose rate comparison to other incidents and standards, with graph of recorded radiation levels and specific accident events from 11 to 30 March in 2011.
The World Radiation Monitoring Center (WRMC) is the central archive of all Baseline Surface Radiation Network measurements. In 1992 the WRMC was founded at ETH Zurich. Since 2008-07-01 the WRMC is hosted by the Alfred Wegener Institute. Data were transferred to AWI from the original ftp-site at ETH Zurich until about 2008-03-01. More recent ...
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.
Displayed background gamma radiation level is 9.8 μR/h (0.82 mSv/a) This is very close to the world average background radiation of 0.87 mSv/a from cosmic and terrestrial sources. Cloud chambers used by early researchers first detected cosmic rays and other background radiation.
The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites (including the ISS) to higher-than-usual levels of ionizing ...
