Bill, I've put WXView.java and the data file, t02a_010_06_00_1025_TMP into pub/incoming on your ftp server. You run the program as: java WXView t02a_010_06_00_1025_TMP I'll look into the missing data issue, but this is supposed to be output from an MM5 dataset. It is supposed to be a 144x120 grid, but I'm not sure if I've read the dimensions in the correct order. I played with changing to 120x144, but it looked about the same. Also, I am running under Solaris with the Reference release of JDK1.2 and Java3D. The data file is binary and was written from a C program called wgrib for extracting slices of data from a GRIB file. Thanks, KathyLee.
