Hoang Dothe: I have made 3 vertical profiles of NO densities from Ray Roble's tigcm model for the ut's you requested. I put the postscript file containing the 3 frames on anonymous ftp on the machine hao.hao.ucar.edu. The directory is /pub/foster and the file name is forsharma.NO.ps. These are actually all from day 120 (4/30/91). Also the f10.7 fluxes are slightly different that those you suggested (the model used f10.7 daily of 161.7 and f10.7 80-day mean of 205.7). Please let me know if you have received this file and if you can print it ok. Also let me know if you would like to have the numbers as well as the plot. --Ben ----------------------------------------------------------------------- Ben Foster High Altitude Observatory (HAO) foster@ncar.ucar.edu phone: 303-497-1595 fax: 303-497-1589 Nat.
