the
data card switches.
B - An entire report is excluded from

card switches.
B - An upper-air category 4

level is excluded from processing if its spanning levels with reported
pressure and/or height are out of order.
B - An entire flight level
reconnaissance
report (report type 132/232) which is reporting an estimated sea-level
pressure is excluded from processing if its reported sea-level pressure
is less than 938.25 mb or greater than 1063.25 mb. The surface mass
data
for this report will later be processed as a surface report with report
type 182 (reconnaissance report with estimated mean sea-level pressure).
C - When ATOVS processing is set to

marine ATLAS buoy reports.

exception
is height, where the limit is 99999.
B - In general, all observational
data
on a pressure level that is a duplicate to another pressure level in
the
report is excluded from processing if its quality marker is worse or
the
same as the duplicate value.
N - An entire Indian satellite
