FRM4GHG raw dataset from the Sodankylä campaign

The dataset contains raw data from 5 participating remote sensing instruments, namely: * Bruker IFS 125HR – operated by Finnish Meteorological Institute (FMI, Finland), * Bruker Vertex 70 – operated by Royal Belgian Institute for Space Aeronomy (BIRA-IASB, Belgium) and University of Bremen (Uni. Bremen, Germany), * Bruker EM27/SUN – operated by Karlsruhe Institute of Technology (KIT, Germany), * Bruker IR Cube – operated by University of Wollongong (Uni. Wollongong, Australia), * Laser Heterodyne Radiometer (LHR) – operated by Rutherford Appleton Laboratory (RAL, United Kingdom), and an in-situ instrument namely: * AirCore – operated by University of Groningen (Uni. Groningen, The Netherlands) and Finnish Meteorological Institute (FMI, Finland). In addition, it also contains the auxiliary data from the meteorological station and the corresponding NCEP pressure-temperature profiles for the measurement days. Note that the file size of the data is about 600 GB, so make sure that this space is available on your server. At a minimum of 2 months prior to publication or presentation of works that include FRM4GHG data, please, contact the authors and provide a description of the intended publication or presentation. If any of the FRM4GHG partners makes a significant intellectual contribution to the research, or if FRM4GHG data is essential to the work, co-authorship of the FRM4GHG consortium would normally be expected. This should be discussed at an early stage in the work. If none of the FRM4GHG partners responds after 3 emails distributed over a 2-months period, the data are licensed under a cc-by 4.0 license.
