Could you please assist? bThanks The IDV does not handle the names of the variables LAT and LON as Latitude and Longitude. Much like your colleagues, you'll need to pass this through a Jython procedure to get it in the right form. The following Jython code will modify the data so it can be correctly displayed. From the Edit->Formulas->Jython Library menu, bring up the Jython Library Editor and paste in the following: def makeUrlToRaster(a): from visad import * from visad import RealTupleType from visad import Gridded2DSet from ucar.unidata.data.grid import GridUtil dom1 = GridUtil.getSpatialDomain(a) samples = dom1.getSamples(0) sets = dom1.getSets() sdomain = Gridded2DSet(RealTupleType.SpatialEarth2DTuple, samples, sets[0].getLength(), sets[1].getLength(), dom1.getCoordinateSystem(), dom1.getSetUnits(), dom1.getSetErrors(), 0, 0) image = GridUtil.setSpatialDomain(a,sdomain) return image Then, use the Edit->Formulas->Create Formula dialog to create a formula to call this procedure. For the Name, enter a name you want For the formula, enter makeUrlToRaster(a) then click OK. Load in your dataset. Since this is a very large dataset, I would suggest using a stride of 10 (e.g., 1:10:4195) for the image (every 10th pixel), or subset the region of view or you will run into memory problems when you try to display the image. Once the image has been added, select the Formula you made in the Fields portion of the Field Selector and select a Color Shaded Plan View display, then click Create Display. From the Field select that pops up, select your image ((lon, lat) -> (sst)). You should see the display in the main window.
