UALIST -- Lists upper-air data
   UALIST station time day <keywords>
Parameters:
   station | 3- or 4-character station ID or 5-digit station ID number,
             e.g., KGRB or 72645
   time | observation time (def=0 if current time is between 0 UTC and
          11:59 UTC, otherwise def=12)
   day | observation date; valid formats include YYYYDDD, YYYY/MM/DD and
         DD/MON/YYYY where YYYY, DDD, MM and DD are integers and MON is
         3 or more letters, e.g., JAN or JANUARY (def=current)
Keywords:
   ANAlysis=YES | include sounding/parcel analysis if OPT=ALL, ANL or
                  MAN is specified (def)
           =NO  | suppress sounding/parcel analysis in all cases
   COuntry=c1..cN | list data for soundings in these countries; specify up
                    to 6 countries using their two-letter codes; use CCODE
                    command to list valid codes
   DATaset=mand sig | source ADDE point dataset names for mandatory- and
                      significant-level data; specify as group/descriptor
                      or alias; specify NONE in the 'sig' value or OPT=MAN
                      or SIG=NO keyword to use only mandatory data, i.e.,
                      ignore significant data (mand def=RTPTSRC/UPPERMAND;
                      sig def=RTPTSRC/UPPERSIG if mand=RTPTSRC/UPPERMAND,
                      otherwise sig def=NONE)
   DEPth= | depth from surface, in mb, to include in parcel analysis; the
            range is 0-400 where 0 means use only surface data (def=100)
   LAT=slat nlat | list data for soundings in this latitude range, where
                   'slat' & 'nlat' are the southern & northern latitude
                   limits, respectively
   LON=elon wlon | list data for soundings in this longitude range, where
                   'elon' & 'wlon' are the eastern & western longitude
                   limits, respectively
   OPTion=ALL | list all mandatory and significant levels with computed
                potential temperature and mixing ratio at each level;
                temperatures are interpolated at each significant wind
                level and winds are interpolated at each significant
                temperature level; include a sounding/parcel analysis
                below the sounding data unless ANA=NO is specified (def)
         =ANL | list sounding/parcel analysis only; the data at each
                mandatory and significant level is not listed
         =MAN | list mandatory levels with computed potential temperature
                and mixing ratio at each level; include a sounding/parcel
                analysis below the sounding data unless ANA=NO is specified
         =RAW | list all mandatory and significant levels with computed
                potential temperature and mixing ratio at each mandatory
                and significant temperature level; do not include
                interpolated temperatures at significant wind levels or
                interpolated winds at significant temperature levels;
                do not include a sounding/parcel analysis
   SIG=YES | include data from significant-level dataset specified in
             DATASET keyword (def)
      =NO  | do not include data from significant-level dataset specified
             in DATASET keyword; use only its mandatory-level dataset
   STate=s1..sN | list data for soundings in these states; specify up to 6
                  states using their two-letter state P.O. abbreviations
   UNIt=t spd z p | units in which to list sounding parameters, where
                    t=temperatures; spd=wind speeds; z=heights; p=pressures;
                    run CU LIST to list valid units and abbreviations
                    (def=C KTS M MB)
Remarks:
   A sounding/parcel analysis is listed with OPT=ALL, ANL and MAN. The
   analysis is performed using mandatory- and significant-level data for
   OPT=ALL and OPT=ANL. The analysis is performed using only mandatory-level
   data for OPT=MAN. Each parameter in the analysis includes a description,
   abbreviation, value and units. The UAPLOT and HODO commands use these
   abbreviations for the values along the bottom of their diagrams.
