ExoMars 2016 ACS Raw-level Data Product Collection

ACS The Atmospheric Chemistry Suite (ACS) instrument is an element of the Russian contribution to the ESA/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_raw collection The raw data collection contains the raw science and housekeeping data from the instrument and the data is released publicly on a daily basis with a six month lag from the data being obtained. Physically the collection is organised by science phase, then orbit range in groups of 100 orbits, then orbit.Different data types e.g. HK plus science from different channels may be mixed in this time related directory. A description of the raw data products is given in the ACS Experiment to Archive InterfaceControl Document (EAICD), available under the Documents tab in the PSA user interface or via the DocumentCollection on the PSA ftp page (http://archives.esac.esa.int/psa/ftp/ExoMars2016/em16_tgo_acs/document).
