ExoMars 2016 ACS Calibrated Data Product Collection

ACS The Atmospheric Chemistry Suite (ACS) instrument is an element of the Russian contribution to theESA/Roscosmos ExoMars 2016 Trace Gas Orbiter (TGO) mission. The instrument hardware was built in theSpace Research Institute of the Russian Academy of Sciences (IKI) with international collaborations of LATMOS (CNRS) in France, the German Institut für Planet enforschung (DLR) and the Institute of Physics of interplanetary Space (IFSI) in Italy. ACS consists of three separate infrared channels,sharing common mechanical, electrical, and thermal interfaces: NIR (0.73 to 1.6 μm),MIR (2.3 to 4.3 μm) and TIRVIM (or TIR, 1.7 to 17 μm). Measurements are carried out in solar occultation mode for all channels, and in nadir mode for NIR and TIRVIM. Note that TIRVIM was working in science mode up to December 3rd, 2019. This ensemble of spectrometers has been designed and developed in response to the TGO objectives that specifically address the requirement of high sensitivity instruments to enable the unambiguous detection of trace gases of potential geophysical or biological interest. The Principal Investigator is Oleg Korablev, Space Research Institute (IKI),Russian Academy of Sciences. The data_calibrated collection The calibrated data collection contains the calibrated science data from the instrument for all channels.MIR and NIR calibrated products are also complemented by browse (contained in the browse_calibrated collection) and geometry (contained in the geometry collection) products.The data are delivered to the PSA from IKI and any data older than six months is immediately released publically. Physically the collection is organised by science phase, then orbit range in groups of 100 orbits, then orbit. A description of the calibrated data products is given in the ACS Experiment to Archive Interface Control Document (EAICD), available under the Documents tab in the PSA user interface or via the Document Collection on the PSA ftp page (http://archives.esac.esa.int/psa/ftp/ExoMars2016/em16_tgo_acs/document).
