This is because when SOURCE is specified the first OUTPUT hiory is always a copy of the requested SOURCE history, including info re TIGCM or TIEGCM. You probably started each run from a SOURCE history that is TIGCM, so that was copied over to first OUTPUT history, e.g., 5:0:0 of LT2001. All remaining histories in LT2001 (5:1-6:1) are TIEGCM. Then you continued the run without giving SOURCE, so all histories on 2002 are also TIEGCM. I have'nt checked the other volumes, but I bet the same thing happened there. You should not have to remake these runs. You should be able to look at ion drifts or epot from all but first histories of each run with tigcmproc, however tigcmloc is a bit of a problem. What you should do is just leave off the first history in tigcmloc runs. This may make the plot look a bit weird, esp local time axis, but it should work. But if what I think is true, then there is no electric potential (and therefore ion drifts cannot be calculated) on the first histories only, so they cannot be included in a plot of those fields. If this is really a problem, maybe you could make a single 6-min step run, specifying the TIGCM history as SOURCE, specify START as 4,23,54 and writing a TIEGCM output history at 5,0,0. Then use that for the 5,0,0 (first) history in tigcmloc. --Ben
