Robert,

There is at least one problem and perhaps two here:
o the IRAB schema for mandatory level upper air data does not allow
for levels above 100 mb:
" (JSP) IRAB PYEATT 0390 SCHEMA-- UPPER AIR DATA, MANDATORY LEVELS
" NAME VSN DATE ID "TEXTID
" ---- --- ----- -- -------
SCHEMA IRAB 4 98231 0 "INTL. RADIOSONDE OBS (UPPER AIR DATA)
" KEY SCALE UNITS
" ---- ----- -----
ROWS 8 "ALLOW ROOM FOR 8 REPORTS/DAY
DAY CYD "YEAR AND JULIAN DAY (CCYYDDD)
TIME HMS "NOMINAL TIME (HH0000)
NREC "APPROX. # OF RECORDS WRITTEN IN THIS ROW
COLUMNS 1500 "ALLOW ROOM FOR 1500 REPORTING STATIONS
IDN "STATION NUMBER
LAT 4 DEG "RANGE (-90 => +90) POSITIVE NORTH
LON 4 DEG "RANGE (-180 => +180) POSITIVE WEST
ZS M "ELEVATION
ST CHAR "STATE ID
CO CHAR "COUNTRY ID
DATA
MOD "USER MODIFICATION FLAG
" 0 = UNMODIFIED
" 1 = MODIFIED BY USER
" 10 = DERIVED FROM SIGNIFICANT LEVEL DATA
HMS HMS "ACTUAL TIME OF REPORT (HHMMSS)
REPEAT 15
LEV CHAR "LEVEL (SFC OR TRO OR SAME AS P)
P 1 MB "PRESSURE
T 2 K "TEMPERATURE
TD 2 K "DEW POINT TEMPERATURE
DIR DEG "WIND DIRECTION
SPD 1 MPS "WIND SPEED
Z M "HEIGHT
ENDSCHEMA
You can see that the REPEAT group only allows for 15 levels:
SFC, 1000, 925, 850, 700, 500, 400, 300, 250, 200, 150, 100,
TRO1, TRO2, MAXW
Some time ago, Don submitted an inquiry to SSEC regarding support of more
vertical levels in their standard upper air schema, and they responded
that this was a good idea. The unfortunate fact is that the needed mods
have not been made to routines in the latest McIDAS release, 7.501,
so you will be unable to process data above 100 mb. I will reissue
the inquiry (actually I will call someone) and see what the status
of it is.
