Hi Don: We are doing another huge refactor to deal with these very large grib collections, funded by NCDC. Its on the 4.5 branch which uses Java 7. If you want to be a beta tester, Ill let you know when its ready (probably Jan, but might be sooner). John > Hi- > > We are looking at the possibility of serving up NOAA's new GEFS > Reforecast2 dataset through our TDS. This dataset was just announced in > the latest Bulletin of the AMS: > > http://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-12-00014.1 > > This is a huge dataset (>130 TB).
