This library contains a set of scripts to extract data from the RU-WRF model.
The most useful functions are:
- wrfptextract_grib.py - Extracts timeseries for a set of specified data points from the older v3.6 model runs, prior to 12/1/2017.
- wrfptextract_nc.py - Extract timeseries for a set of specified data points from the newer v3.9 model runs, starting 12/1/2017.
Both of these functions can be run using the following syntax:
./wrfptextract_nc.py 20190401 -d30 -c wrf_bpu_points.csv -f 1
- yyyymmdd is the date to start the extraction
- -d is used to specify the number of days to extract. The default is 1 day.
- -c specifies the filename that includes the lat/lon points to extract timeseries data points for
- -f specifies how many forecast hours to skip at the beginning of the run. The default is 6 hours.
- -p specifies the prefix to prepend on the outputted file.

- NEED TO VERIFY THESE WITH EXACT DATES AND LEVELS
- 8/1/13 and 9/1/13 have the dimensions (11, 376, 390) and heights: [10 60:10:150]
- 10/1/13 (or perhaps mid Sept) and on has the dimensions (11, 324, 324) and heights
- 12/1/14 (really 11/28) and on has the dimensions (15, 324, 324) [10:10:150]
- 6/1/15 and on has the dimensions (20, 324, 324) and heights [10:10:200]
