FTIR acetylene (C2H2) groundbased remote sensing at Porto Velho from instrument BIRA.IASB004

FTIR acetylene (C2H2) total columns and low vertical resolution profile data at Porto Velho (Brazil). Details on the FTIR retrieval technique can be found in a paper describing our Reunion Island data (https://doi.org/10.5194/acp-12-10367-2012). The retrieval parameters used in the present C2H2 time-series at Porto Velho are following this latter study. Data users are kindly invited to collaborate to ensure a proper use of the FTIR data (e.g. appropriate use of the averaging kernels). The guidelines in the GEOMS documentation should be used to select the latest version of a data file in case files have overlapping dates.
