HySpex - Level 2 Hyperspectral Images - Bohemian Forest

This collection contains airborne hyperspectral imagery acquired by the EOC user service OpAiRS. The data was recorded with the airborne DLR EnMAP simulator, which contains two HySpex cameras manufactured by the Norwegian Company NEO. The survey has been conducted within the scope of the “Data Pool Initiative for the Bohemian Forest Ecosystem”. It covers parts of the Bohemian forest, mainly the Bavarian Forest National Park. The data are made available as orthorectified ground reflectance. For more information concerning the airborne sensor system the reader is referred to: https://www.dlr.de/eoc/en/desktopdefault.aspx/tabid-11411/19998_read-46623/

ELFIN-L Level 1 EPD (Electron Losses and Fields INvestigation on board the Lomonosov satellite, Electron Particle Detector)

The objective of the Lomonosov satellite development concerns the studies of the ultra-high energy cosmic rays and fast processes in optic, X-ray and gamma-ranges which occur in the upper layers of the Earth's atmosphere and in the Universe. This dataset consists of electron particle detector (EPD) counts data of the ELFIN-L instrument which has been described in Shprits et al. (2018). The data rate is 2 measurements per second on 8 physical electron detectors with 12 sub-channels from 21 keV to 4.7 MeV. The data is available from May to November 2016. Due to commissioning-phase and changes in the detector configuration only data from August to November 2016 is usable. Some of the electron detector channels do not provide valid or other than noise measurements. The valid channels are for 21 keV, 30 keV, 44 keV, 1.006 MeV and 1.600 MeV.
