This dataset is the Met Office Unified Model data that was used in the SASSO-funded study:
Damany-Pearce, L., Johnson, B., Wells, A. et al. Australian wildfires cause the largest stratospheric warming since Pinatubo and extends the lifetime of the Antarctic ozone hole. Sci Rep 12, 12665 (2022). https://doi.org/10.1038/s41598-022-15794-3

As part of the SASSO project researchers collaborated with the Met Office and used the UK Earth System Model (UKESM1) to investigate the impact of the intense wildfires and resulting smoke injections in the stratosphere. The work concluded that: Australian wildfires cause the largest stratospheric warming since Pinatubo and extended the lifetime of the Antarctic ozone hole. Data provided here is from the UKESM1 simulations used in those investigations.

Specifically the data consists of zonal mean air temperature (T) and horizonal wind (U) as monthly means. These are monthly means from a single year, since the simulations in the study ran just for a one year. In the dataset there are 3 groups of simulations, each with its own folder: "aerosol_and_ozone", "aerosol_only" and "ozone_only". In each group there are 10 simulations making up a 10 member ensemble. The zonal means are the average across all longitudes (-180 to 180).
