I'm with the Ohio River Forecast Center and we generate Stage-III (now
called MPE - Multi-sensor Precipitation Estimator, due to a number of
algorithmic changes) data for the Ohio River basin and surrounding
area. The problem is, few of the 13 River Forecast Centers (RFCs) save
the data in NetCDF format. The data format used by all RFCs is called
'xmrg' format (a binary file), which is unique to RFCs. However, there
is a C program (source available) that will decode this data and write
it to an ASCII lat-lon-value file from which you can easily reformat to
import into GRASS, re-sample the data, and display in whatever
projection you desire - I have a script that does this (also available).<br>

<pre wrap="">GRASS users,
Is anyone aware of a method to import NEXRAD radar stage III
precipitation estimates into GRASS 5.x as a raster or GRASS ASCII
raster? It appears as though ‘r.stage3’ works only with NetCDF data
provided by the River Forecast Centers (maybe only the Arkansas Red
Basin River Forecast Center), but I’d like to import free radar provided
from NCDC at this site:
<a class="moz-txt-link-freetext" href="http://has.ncdc.noaa.gov/plclimprod/plsql/HAS.FileAppSelect?datasetname=7000">http://has.ncdc.noaa.gov/plclimprod/plsql/HAS.FileAppSelect?datasetname=7000</a>
into GRASS 5.x. The data files from this web site are the raw stage III
data from NOAA/National Weather Service.

If it helps: since a few days GDAL supports netcdf, should be general
netcdf support (fetch the GDAL-CVS version and compile).
