ACCESS-OM2-025 simulation output for England et al. (2025) "Drivers of the extreme North Atlantic marine heatwave during 2023"

This record contains ACCESS-OM2-025 simulation output accompanying the paper: England, M., Zhi, L., Huguenin, M., Kiss, A., Sen Gupta, A., Holmes, R. and Rahmstorf, S. (2025) Drivers of the extreme North Atlantic marine heatwave during 2023, Nature, https://doi.org/10.1038/s41586-025-08903-5 Data is provided for the two simulations used in the article: ACCESS-OM2-025_ERA5; the ERA5 forced version of ACCESS-OM2-025. ACCESS-OM2-025_JRA55; the JRA55-do forced version of ACCESS-OM2-025. Netcdf files are organised per year, for each of the years 1980-2010 (the climatology period) and 2023 (the analysis period). For the JRA55 run, data is only provided for the May-August months, which were the focus of the analysis. Each file contains monthly averages of the following variables: temp; the Conversative Temperature over the top 300m salt; Practical Salinity over the top 300m lw_heat; the net longwave heat flux across the sea surface swflx; the net shortwave heat flux across the sea surface sens_heat; the net sensible heat flux across the sea surface evap_heat; the net latent heat flux across the sea surface net_sfc_heating; the net surface heat flux across the sea surface mld; the mixed layer depth determined according to the 0.125kgm-3 density criterion sw_pen; the shortwave heat flux across the base of the mixed layer Variables are only provided over the North Atlantic region (100W-10E, 0-60N).
