Bangladesh Wind Data Download

The modeled Bangladesh Wind Dataset created with the Weather Research and Forecasting (WRF) model (www.wrf-model.org) contains data simulated between 12:00 AM UTC on 1 Jun 2014 and 23:00 PM UTC on 29 Dec 2017. Observational data (surface reports, radio-soundings, aircraft reports and satellite winds) from NCAR's ADP historical database, as well as nine local observation stations maintained by NREL, were assimilated with the Four-Dimensional Data Assimilation (FDDA) algorithm. CFSR data were used as boundary and initial conditions. The spatial resolution of the dataset is 3 km.

For more information about the data, please contact windtoolkit@nrel.gov

Available Data

Below is a description of the downloadable data directories available via the Globus client.

h5_files

Yearly HDF5 Files at hourly timesteps compliled from the files in the wrffields directory. Variables include:
  • Direct Normal Irradiance (DNI)
  • Global Horizontal Irradiance (GHI)
  • Diffuse Horizontal Irradiance (DIF)
  • Inverse Monin-Obukhov-length (1/L) (2m)
  • Relative humidity (2m)
  • Windspeed (heights of 10, 30, 40, 60, 80, 100, 120, 140, 160 and 200m)
  • Wind direction (heights of 10, 30, 40, 60, 80, 100, 120, 140, 160 and 200m)
  • Temperature (heights of 10, 30, 40, 60, 80, 100, 120, 140, 160 and 200m)
  • Pressure (heights of 10, 30, 40, 60, 80, 100, 120, 140, 160 and 200m)
Each variable is 8760 rows long, each row consisting of values for 71,145 sites. Site metadata can be referenced in the meta variable. Moreover, for each variable, null data values are captured in a fill_value attribute, integer scale factors in a scale_factor attibute, and units in a units attribute.

Observations

Observation site information. Each site contains the following directories:

  • Installation Report (includes maps and photos)
  • Summary Report
  • Raw Data Zip File - One Minute Data
  • Raw Data Zip File - Ten Minute Data
  • Raw Data Zip File - Hourly Data
  • Data Summary Zip File- One Minute
  • Data Summary Zip File - Ten Minute
  • QAQC'd Data Zip File

SOMS

These are the files resulting from the extension of 3-year simulations to 15 years to create a long-term reference. The six identified regimes were downscaled with the WRF model down to 3-km grid spacing for the month of July.

Wrffields

This directory contains the raw WRF output data.

wrflatlon_d003.gz

This is a file containing latitude and longitude information about the grid points in the raw WRF output files from the wrffields directory.

Before You Begin

You'll need a Globus, Google, or ORCiD iD account to transfer data to your local machine. To create a Globus account, visit https://www.globusid.org/create.

Also, note you'll also need to install software locally if you have not used Globus before. More information on this can be found in step 2 below.

Transferring Bangladesh Wind Data

  1. Visit https://www.globus.org/, then log in with your preferred credentials.
  2. If you have not already done so, add your local machine as a Globus Connect Personal endpoint.
    1. Click Endpoints

      The Globus main page with access below the header to the Endpoints menu.

    2. Click add Globus Connect Personal endpoint

      The 'add Globus Connect Personal endpoint' button on the Manage Endpoints page above the Endpoint List.

    3. In Step 1 add a name for your local machine endpoint as the Display NameAdding a Display Name for the new personal endpoint in the Step 1 box.

    4. Click Generate Setup Key
    5. Choose the appropriate software to install on your local machine.
      Note: Once the install is complete you'll need the Setup Key to activate the endpoint.
  3. Navigate back to Transfer Files

    Accessing the Globus main page with the Transfer Files button below the Globus header.

  4. In the left-most Endpoint window, search for and add nrelgds#bangladesh_wind. You'll now have access to the data directories described above.

    Loading the bangladesh_wind endpoint to the left window of the File Transfer page.

  5. In the right-most Endpoint window, search for your local endpoint. It may be found under the Administered By Me tab.

    Loading the new personal endpoint to the right window of the File Transfer page.

  6. Select the data Path to the left that you will transfer from Globus.
    Selecting the files to download from the left window of the File Transfer page.

  7. Select the destination Path for the data on your local machine to the right.
    Selecting the destination location for the file download from the right window of the File Transfer page.

  8. Below the Transfer windows, provide a label for the transfer.

    Naming the file transfer at the window below the right and left endpoint boxes on the File Transfer page.

  9. Click the right-most arrow at the top of the page to begin the transfer.

    Selecting the right arrow at the top of the right and left endpoint boxes on the File Transfer page to initiate the transfer.
