Hanli: I still havent found the bug re the 14th dispose of secondary history files to mss. However, you should be able to make your run if you save the sec hist files less often, e.g. every 6 hrs instead of every hour. You can still have >13 histories on a volume, just don't save as often to mss,e.g: SECHIST = 0,1,0 SECSAVE = 0,6,0 You should restart your run from Ray's source volume again, i.e., repeat your 1st day. Make sure tmpdirs are clean of relevant files before you start and that you include all fields you will want on the secondary histories. Probably best to run on antero. Stop after the 1st day and thoroughly check all histories w/ f90 tgcmproc. Also, as we discussed before, when you restart for the next day(s), you don't need to specify SOURCE if the source history you need to start is in OUTPUT. I will let you know when I find the bug.. --Ben
