This dataset contains vertical profiles and total columns of ozone, carbon monoxide, methane, and nitrous oxide, from 2008 to 2022, retrieved from the PEARL E-AERI, located at Eureka, Nunavut, Canada (80N, 86W). These data are used in 'Autonomous year-round measurements of O3, CO, CH4, and N2O in the High Arctic with the Atmospheric Emitted Radiance Interferometer" by Hung et al. (submitted 2024). There is one netCDF file for each trace gas, and each includes the following data variables: timestamp for each retrieval (time), total column (tcol), degrees of freedom of signal (dofs), vertical profile information as a volume mixing ratio (vmr), final RMS residual for retrieval (rms), averaging kernel matrix, as a flattened 1D array (ak), a priori VMR profile (ap_vmr), total retrieval error (err), pressure profile (P), temperature profile (T), and retrieval grid representing the midpoints of each layer in the model atmosphere (z).
