Included in this repository is CESM2(WACCM6) Earth system prediction framework forecast output necessary to replicate the results of "Delayed surface impacts of the January 2021 sudden stratospheric warming". Standard forecast output is formatted as "ssfcst_ddMMM", where ddMMM is either 04jan or 08feb. Forecasts initialized January 4th, 2021 with scrambled initial conditions are formatted as: "15to20kmRampBot_", for scrambled tropospheric initial conditions; "9to12kmRamp_" for scrambled stratospheric initial conditions; and "2017noSSW_" for scrambled atmospheric initial conditions started from a January 2017 atmospheric restart. The forecast initialized February 8th, 2021 with scrambled tropospheric initial conditions is formatted "15to20kmRampBot_update_". All files contain relevant dimensions. "mXX", where XX is between 0 and 20, denotes the forecast member. Geopotential height is in the "Z3" files, surface temperature is in the "tas" files, and zonal mean zonal wind and tropopause pressure are in the "h2" files.
