Data underlying the figures of "An incoherent broadband cavity-enhanced absorption spectrometer for simultaneous NO3 and N2O5 measurements, integrated into a NOy instrument suite: characterization and first field deployment"

This dataset contains the data plotted in the figures of “An incoherent broadband cavity-enhanced absorption spectrometer for simultaneous NO$_3$ and N$_2$O$_5$ measurements, integrated into a NO$_y$ instrument suite: characterization and first field deployment” (DOI: 10.5194/egusphere-2026-5307). It includes the NO$_3$ cavity-enhanced absorption spectrum with its fit, reference cross-sections and residual; simulated NO$_3$/N$_2$O$_5$ thermograms; NO$_3$ wall-loss measurements and fits; overlapping Allan deviations of the two instrument channels; Monte Carlo simulation results on the retrieval bias and detection limit; and measured data as well as derived quantities from a night during the instrument's first field deployment at the ACROSS campaign. Each file is a tab-separated text file whose header lists the units, columns, and the fit or simulation parameters. The dataset contains the plotted, fitted and simulated data only, not the raw instrument files.
