Hi Delores: I ran the processor for days 75-85 of a tiegcm run of Ray's. There are hourly data for each day. Rho is in gm/cm-3. I made line plot profiles of rho at every hour (100-500 km), and then a single contour plot w/ ut on x-axis, and height on y-axis. Also made an equivalent ascii data file. The plots and ascii data are in: http://download.hao.ucar.edu/pub/foster/knipp -rw-r--r-- 1 foster ftp 2926 Mar 3 15:36 rdascii.f -rw-r--r-- 1 foster ftp 490442 Mar 3 15:36 rho.d75-85.dat -rw-r--r-- 1 foster ftp 6198360 Mar 3 15:36 rho.d75-85.ps The .dat file is the ascii data file, the .ps file are the postscript plots, and the .f file is a small fortran example program that read the .dat file.. Its very easy to rerun this job with different setup, so let me know if you want to change anything. --Ben
