Steve, I took a quick look at the file and peeked at the Grid Definition Section. According to ToolsUI, we have template 3.0, which isn't a rotated lat/lon grid. We're a little suspicious of the reported grid_template 32768 mentioned earlier. Do you know for sure what the grid is, or did we somehow get a hold of the wrong file? From ToolsUI: GDS hash=-1078949017 crc=3906142641 (3.0) Grid definition template 3.0 - latitude/longitude (or equidistant cylindrical, or Plate Carrée) 1: GDS length == 72 5: Section == 3 6: Source of Grid Definition (see code table 3.0) == 0 (table 3.0: Specified in Code table 3.1) 7: Number of data points == 779385 11: Number of octects for optional list of numbers == 0 12: Interpretation of list of numbers == 0 (table 3.11: There is no appended list) 13: Grid Definition Template Number == 0 15: Shape of the Earth == 6 (table 3.2: Earth assumed spherical with radius of 6 371 229.0 m) 16: Scale factor of radius of spherical Earth == 0 17: Scaled value of radius of spherical Earth == 0 21: Scale factor of major axis of oblate spheroid Earth == 0 22: Scaled value of major axis of oblate spheroid Earth == 0 26: Scale factor of minor axis of oblate spheroid Earth == 0 27: Scaled value of minor axis of oblate spheroid Earth == 0 31: Ni - number of points along a parallel == 669 35: Nj - number of points along a meridian == 1165 39: Basic angle of the initial production domain == 0 43: Subdivisions of basic angle used to define extreme longitudes and latitudes, and direction increments == 0 47: La1 - latitude of first grid point == -7446000 51: Lo1 - longitude of first grid point == 215861000 55: Resolution and component flags == 56 56: La2 - latitude of last grid point == 54000000 60: Lo2 - longitude of last grid point == 254000000 64: Di - i direction increment == 90000 68: Dj - j direction increment == 77000 72: Scanning mode == 64 73: List of number of points along each meridian or parallel. == -9999 Ticket Details =================== Ticket ID: HVC-591098 Department: Support netCDF Java Priority: Normal Status: Closed
