Replication data for: Unprecedented spring 2020 ozone depletion in the context of 20 years of measurements at Eureka, Canada
Borealis
Bognar, Kristof; Alwarda, Ramina; Strong, Kimberly; Chipperfield, Martyn P.; Dhomse, Sandip S.; Drummond, James R.; Feng, Wuhu; Fioletov, Vitali; Herrera, Beatriz; McCullough, Emily M.; Wizenberg, Tyler; Zhao, Xiaoyi — 2020-12-04 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).

Profiles of BrO and aerosol retrieved from PEARL-GBS MAX-DOAS measurements at Eureka, Canada
Borealis
Bognar, Kristof; Strong, Kimberly; Chang, Rachel Y.-W.; Fogal, Pierre; Hayes, Patrick L. — 2020-04-27 Retrieved profiles and partial columns of BrO and aerosol using PEARL-GBS MAX-DOAS measurements taken at the PEARL Ridge Lab in Eureka, Canada. Retrievals were performed on all available data in the springtime halogen activation season (March-May) for 2016-2019 using the HeiPro retrieval algorithm. The files also contain paired weather station measurements from the PEARL Ridge Lab, as well as integrated accumulation and coarse mode aerosol number concentrations from in situ aerosol measurements.
