Gonzalo: Ray asked me to send you data from a timegcm simulation for year 2004. I have put plot files and ascii data files in: http://download.hao.ucar.edu/pub/foster/gonzalo There are 30 days per file (with 4 days in the last set), starting at day 79 and ending at day 263. The .dat files are ascii data files giving the numbers for each frame corresponding to the plot files. The rdascii.pro file is a short IDL procedure showing how to read the ascii data files. You should be able to use a ps previewer to view the .ps files (you can ignore the .cgm files, or use idt from an hao login to view them -- they have the same plots as the ps files, but in a different format). Each file contains 45 frames: Each frame has days on x-axis (hourly data), and field values on the y-axis. Frames 1 ht-integ E5577 Greenline emission (South Pole) 2-5 ht-integ E5577 doppler T,U,V,U+V (South Pole) 6-10 Same as 1-5, but at Arrival Heights 11-15 Same as 1-5, but at Mt. John 16-30 Same as 1-15, but for E6300 Redline emission 31-45 Same as 1-15, but for OH (6-2 band) I hope these are useful to you. Please let me know if you need any other info, or have problems reading these files. --Ben
