WRF and ERA5 Data extraction¶
The very first step in running PostWRF is modifying namelist.wrf:
vi namelist.wrf
Time-series of the WRF variables¶
The first section in namelist.wrf corresponds to the data extraction:
==================== DATA EXTRACTION ======================= WRF_variable_name = pvo +Vertical_profile_plot_on_off = 0 |
After modifying namelist.wrf, run the software by:
./postwrf.sh
- Nearest point
- Bilinear
- IDW

Note
ERA5 data can tbe extracted by the same method. Set ERA5_Extract_On-Off to 1, and WRF_Extract_On-Off to 0. For ERA5 data, only one method (bilinear) is applied for interpolation. Moreover, unlike the WRF data, for ERA5 data the start and end of time slots can be specified.
Plotting vertical profiles (for WRF outputs)¶
If +Vertical_profile_plot_on_off is set to 1, the vertical profiles of the locations (Berlin and London) will be plotted:
