Mike-We (ESRL) think we have fixed the problems with the netCDF grid projections. There are still some issues with the variable names and times which we hope to fix next week, but the projection is okay. If you go back to your link below, try using the netCDF files in the IDV.
Thanks to Cathy Smith at ESRL for the quick fix. Don On 1/27/11 4:45 PM, Mike Hardiman wrote:
Hi folks, For me, one of IDV's strong points has been its ability to work with numerous data formats -- but I've finally managed to trip it up. I tried to load up NARR Composite data in netCDF format, taken from the ESRL web site: http://ow.ly/3LCt2 The above link shows a plot consisting of mwN 700mb Vector Winds from 3 Dates/Times, using NARR. Towards the bottom there are links to download the plotted data in netCDF format for both the U and V-wind components. When downloading these files and trying to load them in IDV, it balks about not finding any gridded data in them. I've tried several 'file type' options. When doing the same thing, except using the NCEP/DOE Reanalysis 2 dataset, I have no problems plotting the netCDF data in IDV: http://ow.ly/3LCxt One note on the ESRL website mentions that the NARR data is pre-projected in Lambert Conformal, and this may be what is tripping up the IDV (though I thought netCDF was supposed to be self-describing when it comes to data projections and domains, etc). There are no explicit instructions from ESRL about using the NARR netCDF data with IDV, but they do provide tips for other software such as GrADS: http://www.esrl.noaa.gov/psd/data/narr/format.html Now, if I download the raw NARR data for individual dates/times in Grib format, IDV handles it just fine. But ESRL's website makes it easy to create composites, whereas I would not really know where to start if I wanted to manually create composites using the Grib data (probably could figure it out with GrADS, but I'm just not there yet). Does anyone have a ready-to-go solution to allow NARR composite data from ESRL to display in IDV?
