John: I have put an ascii data file on anonymous ftp on the machine hao.hao.ucar.edu (the sting machine is begin decommisioned). The directory is pub/foster, the file tspir1.vert.dat. The file contains data for 5 vertical profiles taken from /ROBLE/RGR93/TSPIR1 (0:15:30, i.e., ut=15.5), at the grid point lat,lon=62.5,-145: Frame 1: tn (deg k) 30-389 km Frame 2: co2 (cm-3) 30-389 km Frame 3: o1 (cm-3) 34-389 km Frame 4: co2 (cm-3 mix ratio) 30-389 km Frame 5: o1 (cm-3 mix ratio) 34-389 km There is a value at every kilometer. The heights are given at each frame, followed by the data. I think you've seen this ascii format before. The o1 starts at 34 km rather than 30 km because it went negative at the bottom (zp = -17) at this location. I do an exponential interpolation to height for denstities, so had to skip the negative values. 389 km was the top of the model at this location for this run. Let me know if you need more data... p.s., if you have sting in any email address for me, it will not work after sting goes away (probably next week). The correct address is foster@ncar.ucar.edu. (Let me know if this address ever fails) --Ben
