Ray: I have added the doppler fields to tigcmloc (to use this, set DOPPLER=1 in the file ~roble/tgcm/tigcmloc). I have run this processor for the two tiegcm runs at Fritz Peak for Gonzalo. The plot files are in sting:/d/foster/tigcmloc/gzmnxx.cgm and gzmxxx.cgm. If you need to see how the calculations are made you can look in sting:~foster/lib/doptuv.f and solred.f. BTW, the mss files are GZMN01-04 and GZMX01-04 (not GZNMxx and GZNXxx as in your tiegcm.gonz.log file). Also, I renamed GZMXO1 to GZMX01 on the mss. Histories were found as follows: GZMN02: 7.12, 8.0, 8.12, 9.0, 9.12, 10.0 -> 10.7 (hourly) GZMN03: 10.8 -> 10.20 (hourly) GZMN04: 10.21 -> 11.0 (hourly) GZMX02: 3.6, 3.12,...,5.18, 6.0, 6.1 GZMX03: 6.2 -> 6.14 (hourly) GZMX04: 6.15 -> 7.0 (hourly) --Ben
