CMAM39-SD Subsampled-Model UTLS Climatologies

Zonal-mean ozone and water vapour climatologies generated from the 39-year specified dynamics run of the Canadian Middle Atmosphere Model (CMAM39-SD) subsampled to the times and locations of measurements in the Atmospheric Chemistry Experiment - Fourier Transform Spectrometer (ACE-FTS) version 3.6 and version 4.1/4.2, Atmospheric Chemistry Experiment - Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO) version 3.13 (ozone only) and version 31 (water vapour only), and Odin - Optical Spectrograph and InfraRed Imaging System (OSIRIS) version 5.10 (ozone only) data products. These climatologies are presented in tropopause-relative potential temperature and equivalent latitude coordinates, with the former taken in reference to the 2 PVU dynamical tropopause. The technique used in their generation is described in Jeffery et al. (2022).

For each species and instrument combination, one netCDF file is produced for each month, season (3-month), and year, as well as for the multiyear average of each of these. Each file contains the zonal mean, median, standard deviation, median average deviation, maximum, minimum, and number of measurements for each grid cell in the climatology. Additionally, the mean latitude, longitude, local solar time, and tropopause height of each grid cell is included.

Version 1.0 of the climatologies covers the period June 2004 to May 2018, and are the replication data for Jeffery et al. (2022).
