Introduction
This is a code to easily extract precipitation values (or any value, really) out of a lat/lon cell in a NetCDF of a NEXRAD level 3 product grid.
You can run it, for example, by typing at the command line:
>>> python radar_netcdf.py -vwp --ncfile='KBOU_SDUS35_N1PFTG_201106091630.nc' --varname=Precip1hr --lat=40 --lon=-100
The general syntax is:
python radar_netcdf.py $netcdfFileName $varname [$lat] [$lon]
where $lat/$lon are of the point of interest, and are optional

Input Files
You need a NetCDF of a Nexrad Level III weather radar product. NOAA has a nice Java tool to obtain NetCDF's from their own data format.
Output Files
Right now, the code will only output values (e.g., precip) to a file. I may work on making it be able to do latitude, longitude, and/or time as well.
