John: As per your request of Jan 7, I have put 4 files on anonymous ftp hao.hao.ucar.edu /pub/foster. These are all from the same history as before, i.e., /ROBLE/RGR93/TSPIR1 (0,15,30, i.e., ut 15.5). The files are as follows: tspir1.150-300.cm3.dat 150-300,5km (number densities) tspir1.150-300.vmr.dat 150-300,5km (volume mixing ratios) tspir1.50-150.cm3.dat 50-150,2km (number densities) tspir1.50-150.vmr.dat 50-150,2km (volume mixing ratios) The 50-150km files contain tn,n2,o2,o,co2,h,no,o3,oh,co,h2o,ch4. The 150-300 km files are the same, except without tn. No log10 have been taken in any of the data. Let me know if this is ok. They are pretty easy to make. --Ben
