Design and description of the MUSICA IASI full retrieval product

We present atmospheric H2O, HDO / H2O ratio, N2O, CH4, and HNO3 data generated by the MUSICA IASI processor using thermal nadir spectra measured by the IASI satellite instrument. The data have global daily coverage and are available for the period between October 2014 and June 2021. Multiple possibilities of data reuse are offered by providing each individual data product together with information about retrieval settings and the products' uncertainty and vertical representativeness.This research has been supported by the European Research Council, FP7 Ideas (MUSICA (grant no. 256961)); the Deutsche Forschungsgemeinschaft (grant nos. 290612604, project MOTIV, and 416767181, project TEDDY); the Ministerio de Economía y Competitividad (grant no.
