The times, latitudes and longitudes are rounded to the nearest history (time), and nearest gcm grid point (location). "cm3" means number density, and "vmr" means volume mixing ratios. Tn will be redundant in the cm3 and vmr files. "50-150" means 50->150 km (every 2 km), and "150-300" means 150->300 km (every 10 km). OH is missing in tscir8.ut3b.vmr.150-300.dat. There is a problem in this model run with OH at some locations on the grid. Ray is aware of it. Good Luck, --Ben
