In response to requests for the 40km land-water mask by Rob Burton last week and Kevin Doty in May:
There are now ASCII files for land-water masks from 13km native grid (451 x 337) RUC (operational since June 2005) for interpolated fields to 20km (301 x 225) and 40km (151 x 113) resolution.
There are also gif files available for each of these land-water masks available at http://ruc.noaa.gov/gif/landwater. The degradation of the sharpness of the land-water masks is evident in comparing these figures. The surface fields from the RUC are certainly much clearer using 13km resolution, especially near coastlines.
We recommend that RUC users review the RUC data available from the NCEP ftp server at http://ruc.noaa.gov/ruc20.data-access.html and the access of the RUC data at ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/ruc/prod/.
We hope this information is helpful and sorry it took this long to get a good response out.
