Each sensor contains two micro-dosimeters sensitive to the passage of charged particles from the Earth's radiation belts. There are six distinct dosimeter types spread among the 64 individual sensors, which are unique in shielding and electronic threshold. When taken together, this effectively enables a high time-cadence measurement of protons and electrons in six integral energy channels over the entire globe. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://zenodo.org/record/6423507#.YmMwUfPMLCV REACH data REACH csv files are available at <_Note>URL also in all.xml.
