ACE-FTS Version 3.6 UTLS Climatologies - water vapour & ozone

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, 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.
