This dataset contains data from a number of instruments (and simulations from one model) in Eureka, Canada. The HDF files he contain measurements of HCl and NO2 from the Bruker FTIR (2016-2020), in the GEOMS file format. The HCl data can be found on the NDACC archive as well, and this version differs only in the data filter used (negative VMRs were included here). The CRL_* file contains range-scaled signal measured by the CANDAC Rayleigh-Mie-Raman Lidar for 16-21 March, 2020. Additional details in the file header. The GBS_* files contain BrO and OClO slant columns retrieved from UV Zenith-Sky DOAS measurements (2007-2020, spring data only). Additional details in the file header. The Pandora_* file contains ozone measurements from Pandora #144 (2019-2020, spring only). The ozone columns have been corrected for a temperature-dependent bias. Additional details in the file header. The tomcat_* files contain trace gas profiles over Eureka, simulated by the TOMCAT/SLIMCAT 3D chemical transport model (2000-2020).
