Dataset
Summary
This dataset contains daily-mean output from Ensemble 03 of the UA-ICON Northwest America Gravity Wave Forcing experiment (NA). The experiment features a regional perturbation: the stratospheric component of subgrid-scale orographic gravity wave drag is enhanced tenfold within 30°–60°N, 100°–130°W, representing Northwest America. This particular ensemble member was initialized using the mean January 1 state from ERA5 reanalysis, averaged over the period 1979 to 2022, with the exception of year 1992, which was excluded to create a perturbed initial condition. The dataset spans 30 years, stored in monthly NetCDF files covering the period from 1990 to 2019. However, the year 1990 is treated as spin-up and excluded from the final analysis, so the valid simulation years are 1991 to 2019. The year labels are arbitrary and intended to represent a generic current-climate scenario rather than actual historical years.

Each NetCDF file contains daily-mean values of key atmospheric variables. The data files follow the naming convention:

uaicon_R02B04_NA_003_Daily_<YYYY>_<MM>.nc

where:
<YYYY> indicates the simulation year (ranging from 1991 to 2019)
<MM> represents the month (from 01 to 12).

The dataset includes the following variables: temperature (temp), zonal wind (u), meridional wind (v), vertical velocity (w), pressure (pres), geometric height at full-level center (z_mc), geopotential (geopot), zonal wind tendency from non-orographic gravity wave drag (ddt_u_gwd), meridional wind tendency from non-orographic gravity wave drag (ddt_v_gwd), zonal wind tendency from sub-scale orographic gravity wave drag (ddt_u_sso), meridional wind tendency from sub-scale orographic gravity wave drag (ddt_v_sso), temperature tendency due to both orographic and non-orographic gravity wave drag (ddt_temp_drag), surface pressure (pres_sfc), and 2-meter air temperature (t_2m).
