Jimmy, Are you running SNTSER for a time series of theta at 250MB? What times are in the file 000123_upa.gem? Your taxis is - 24/00-26/12, so make sure these times are in your file. If you aren't sure, use DATTIM=list. Also, your YAXIS should be set for the data values of theta at 250 mb. It appears to still be set for SNPROF's skewt. Either set YAXIS= or seth the YAXIS max/min based on theta values, probably 300 to 400K. If you are trying to do a time series cross section using SNCROSS, then you should be using CXSTNS and not AREA as shown below. Steve Chiswell Unidata User Support On Fri, 12 Jan 2001, J.
