Don, John, Tim, Jeff: I would like to talk about making 3d or volume animations of tgcm results (Thermospheric Gen Circ Models). I have put 2 netcdf files on hao.ucar.edu /pub/foster: foster ftp 2389016 Aug 20 08:44 TSEQNE6_0100000.nc foster ftp 3787352 Aug 20 08:44 TSMAHB9_0160000.nc These contain 7 or 8 fields each, with lev,lat,lon dimensions. There are about 30 other fields available. If you are interested, maybe browse these files and let me known what you think. Thanks, --Ben ----------------------------------------------------------------------- Ben Foster High Altitude Observatory (HAO) foster@ncar.ucar.edu phone: 303-497-1595 fax: 303-497-1589 Nat.
