SKYSPEC EVALUATION PACKAGE

NEAR SURFACE CONCENTRATION AND VERTICAL COLUMN DENSITY RETRIEVAL FOR MULTIPLE GAS SPECIES FROM YOUR SKYSPEC DATA.

THE AIRYX EVALUATION PACKAGE IS DESIGNED FOR AUTOMATIC NEAR-REAL-TIME AND POST PROCESSING ANALYSIS OF SPECTRA RECORDED WITH AIRYX SKYSPEC INSTRUMENTS.

THE PACKAGE MAKES USE OF THE DOAS (DIFFERENTIAL OPTICAL ABSORPTION SPECTROSCOPY) ANALYSIS TECHNIQUE TO DERIVE BOUNDARY LAYER COLUMNS, NEAR-SURFACE-CONCENTRATION, AND DIFFERENTIAL SLANT COLUMN DENSITIES FOR GAS SPECIES DETECTABLE WITH SKYSPEC INSTRUMENTS (E.G., O4, NO2, SO2, HCHO, BRO, H2O, HONO, IO AND C2H2O2).

FEATURES

NEAR SURFACE CONCENTRATION

RETRIEVAL OF AVERAGE NEAR SUFACE CONCENTRATIONS/MIXING RATIOS ALONG THE LINE OF SIGHT OF YOUR SKYSPEC INSTRUMENT.

One week of NO2 NSC. Data from a near-surface open path system is shown for comparison. Furthermore, a reference set of NSCs was derived by feeding the underlying dSCDs to inverse modelling algorithms applying full radiative transport calculations. For further details, see J.-L. Tirpitz et al. (DOI: 10.5194/amt-14-1-2021) and K. Kreher et al. (DOI: 10.5194/amt-13-2169-2020), 1 min exposure time, data recorded in Cabauw, Netherlands.

VERTICAL COLUMN DENSITY

RETRIEVAL OF INTEGRATED BOUNDARY LAYER VERTICAL COLUMNS OF GAS SPECIES DETECTABLE WITH SKYSPEC INSTRUMENTS.

CUSTOMIZABLE SPECTRAL AVERAGING AND FIT PARAMETERS.

ADJUST TEMPORAL AVERAGING AND FIT PARAMETERS OF THE ANALYSIS TO OPTIMIZE TIME RESOLUTION AND SIGNAL-TO-NOISE RATIO.

REAL-TIME AND POST-PROCESSING ANALYSIS

RETRIEVE RESULTS WHILE THE INSTRUMENT IS MEASURING AND OPTIMIZE YOUR ANALYSIS PARAMETERS BY RE-ANALYSIS AND POST PROCESSING.
