The aim of the project KCDC (KASCADE Cosmic Ray Data Centre)
is the installation and establishment of a public data centre for high-energy astroparticle
physics based on the data of the KASCADE experiment.
KASCADE was a very successful large detector array which recorded data during more than
20 years on site of the KIT-Campus North, Karlsruhe, Germany (formerly Forschungszentrum,
Karlsruhe) at 49,1°N, 8,4°E; 110m a.s.l. KASCADE collected within its lifetime more
than 1.7 billion events of which some 433.000.000 survived all quality cuts and are made
available here for public usage via three DataShops. The first, called 'KASCADE', was introduced
in 2013 and has been continuously extended since then. It contains data from four KASCADE-Grande
detectors, which were analysed separately and from the LOPES radio antennas. The second, called
COMBINED, is based on a subsample of the KASCADE-Grande data, but was evaluated in a joint analysis
of the KASCADE and GRANDE detector arrays. Newly added in 2021 was the MAKET-ANI DataShop, which
contains data from the MAKET-ANI air shower experiment at Mount Aragats, Armenia.
