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.

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. >Thanks, >Robert Mullenax Tom
