CESM2 and E3SM variables used for diagnosing westerly wind events

This data set contains variables needed to identify and evaluate westerly wind events (WWEs) in a simulation using the Community Earth System Model version 2 (CESM2) and a simulation using the Energy Exascale Earth System Model (E3SM). The CESM2 simulation was a historical run from 1980–1999 that was restarted from the CMIP6 historical simulation. The E3SM was a 400-year pre-industrial simulation from which we analyzed the last 39 years. Only those last 39 years are included in the E3SM files. 
For both the CESM2 and E3SM simulations, meridionally-averaged zonal wind stress from 2.5°S – 2.5°N filtered from 5–90 days was used to identify westerly wind events in the Pacific Ocean (120°E – 280°E). Events were defined as patches of zonal wind stress in the time-longitude plane with zonal wind stress values of 0.04 Nm-2 or larger that lasted at least 5 days and were at least 10° longitude long. Meridional wind stress was also used along with the zonal wind stress to make spatiotemporal compo..., , , # CESM2 and E3SM variables used for diagnosing westerly wind events

There is a .tar.gz file for both the CESM2 and E3SM variables that were used to diagnose westerly wind events in each simulation. Af the tar files are unpacked there will be 4 directories that contain files for zonal and meridional wind stress, outgoing longwave radiation, and 1000-mb zonal wind speed.

## Description of the data and file structure

The CESM2\_rlut\_tauu\_tauv\_ua.tar.gz file contains the following directories and files when unpacked, where each file contains one 3D variable with 64°lat x 288° lon and 7301 days. An ncdump on each file will show the metadata.

rlut -> CESM2.0\_B1850.cam.h1.FLUT.30S-30N.00010101-00210101.nc
The rlut variable is the outgoing longwave radiation (W/m2)

tauu -> CESM2.0\_B1850.cam.h1.TAUX.30S-30N.00010101-00210101.nc
The tauu variable is the zonal wind stress (N/m2)

tauv -> CESM2.0\...
