HP/Robert- There are restrictions on the use of ECMWF data. At one time it was publicly available on our models catalog, but we were asked to take it off. ECMWF and UK met grids are available in the NWS NOAAPort stream, but again, because of restrictions, we can't make them publicly available. At present we have no mechanism to restrict the access to the online catalogs. As for HP's comment about reading the grids, the IDV currently cannot handle the quasi-regular "thinned" grids in GRIB1 format. We are currently working on that and hope to have something for users to test in the next week or so. The IDV handles these grids when they are in GRIB2, but not GRIB1. If there are other GRIB1 products that the IDV does not handle (besided tiled grids), please let us know. Don Murray HansPeter Roesli wrote:
Hi RobertI am regularly usig ECMWF grib data from their archive called MARS. I must say however, that I am priviliged user and have access to the full archive, and to the operational model in particular :-) Working with ECMWF data I observed that IDV only reads grib2 data sets. ECMWF's grib1 dialect is not understood by IDV - and this might be the root problem. Publicly available data (being mainly re-processed data sets from projects and not "real-time" data from the operational models) is most probably always grib1, whereas forecasts and analyses from the operational model are in grib2. But you might try harder and search whether ECMWF offers also some publicly available data sets in grib2. I have not already done it go to services/archive on www.ecmwf.org and/or ask directly at mars@xxxxxxxxxChees, HP Robert Reed wrote:Does anyone know where I could download ukmet and ecmwf grib datasets for use in the IDV? I appreciate the parameters are very limited when it comes to publically available grib datasets from the European nwp. The only ones I`ve found have a wierd prefix at the end, and besides IDV doesn`t like them. ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/mrf/prod
