Aerosol optical depth (AOD) and solar irradiance data acquired in the frame of the JRP project MAPP, Metrology for Aerosol Optical Properties 19ENV04 with the Precision SpectroRadiometer PSR-009 (Gröbner and Kouremeti 2019). The calibrations of the PSR-009 have been performed at PMOD/WRC while the straylight correction has been measured at PMOD/WRC and PTB. The Top-of-Atmosphere solar spectrum convolved with the slit functions of the PSR, used for the AOD retrieval is stated in the field PSR.FN_ETS · PSR_009_QASUMEFTS_env03_cosi_kittpeak_thullier_LSF_SLITextFillLSF.mat: QUASUMEFTS (Gröbner, Kröger et al. 2017) (300-450 nm) and ATLAS (Thuillier, Hersé et al. 2003)(450 nm -1030 nm) · PSR_009_QASUMEFTS_TSIS_HSRSall_LSF_SLITextFillLSF.mat: QUASUMEFTS (Gröbner, Kröger et al. 2017) (300-450 nm) and TSIS-1 (Coddington, Richard et al. 2021) (450 nm -1030 nm) · PSR_009_TSIS_HSRSall_LSF_SLITextFillLSF.mat: TSIS-1 (Coddington, Richard et al. 2021) References Coddington, O.
