This repository is an archive of WRF simulations successfully run within the A2e MMC project. These have been tested with a2e-mmc version of WRF (https://github.com/a2e-mmc/WRF), which tracks the NCAR WRF development.

Running setup.sh, will automatically download the initial/boundary conditions from the NCAR Research Data Archive (RDA), and then run preprocessing utilities geogrid, ungrib, and metgrid for real WRF cases.

For more information on running setup.sh, see templates/README.

• SWiFT_20131108_GFS - Reference simulation of the SWiFT diurnal cycle from 2013-11-08 to 09, used in the coupling comparison study. 48 hrs were simulated with 12 hours of spinup, using the GFS reanalysis dataset.
• SWiFT_20131108_PertMethodsGroup - Simulations of idealized convective, neutral, and stable conditions extracted from the SWiFT canonical day between 2013-11-08 to 09, used to study different perturbation methods for turbulent inflow generation. Subdirectories contain the input_sounding, namelist, tslist, and output-control file (which reduces the number of variables that are stored in the wrfout_d0* files).
  • convective: 1800-2000 UTC, specified heat flux of 175 W/m^2
• FINO_20100512 contains the WRF setup script and templates for the offshore FINO simulations for the 13 day period of interest.

ERA5 is a newer reanalysis product that has gotten a lot of positive feedback about how well it simulates past dates (not for forecasting) from 1979 to within 3 months of real time. Downloading the data, for now, is a bit tricky and can get very large.

• Go to https://cds.climate.copernicus.eu/cdsapp#!/search?type=dataset&text=era5 and create an account (if you don't already have one).
• You will need 2 datasets: ERA5 hourly data on pressure levels from 1979 to present and ERA5 hourly data on single levels from 1979 to present
  • For pressure level data, click the download data tab, select all fields within Pressure level and Variable. For Time, you can select all fields, or you can select incremental hours. Just make sure you change your namelist.wps to reflect the time interval you chose. For Product Type select Reanalysis. Then, select the dates of the data you want to download. Choose GRIB as the Format, agree to the terms of service, and then click Submit Form. Once you have done this, you will be taken to a queue where you can see the status of your download and when it is finished, you can download the data (or copy the URL and use wget on Eagle).
  • For surface data, click the download data tab, select the following fields:
    • Product Type: Reanalysis
    • Variable:
      • Popular: 10m u-component wind, 10m v-component wind, 2m dewpoint temperature, 2m temperature, Mean sea level pressure, sea surface temperature, Surface pressure
      • Temperature and pressure: select all fields
      • Wind: 10m u-component wind, 10m v-component wind
      • Snow: select all fields
      • Soil: select all fields
      • Other: Land-sea mask, Sea-ice cover
    • All other fields should be blank
    • Year / Month / Day: select the days that you want
    • Time: make sure you select the same times as above
    • Format: GRIB
    • Accept terms of service and click Submit Form. Download the data when it is finished or use wget as above.
• Rename the files as you please (I have used era5_PRES.grib and era5_SFC.grib).
• Use the V-table for ERA-Interim.pl
• Run WPS as if using ERA-Interim data.
• '''NOTE: ERA5 data are hourly'''; therefore the interval should be changed from 21600 (6 hrs) to 3600 (or to whatever interval was downloaded).
