SSM/I Data (DMI): Details
The SSM/I data have been acquired in near real time from UK Met Office
and archived at DMI. The data are relayed from NOAA/NESDIS as TDR
(Temperature Data Record) data and are repacked in BUFR format at
ECMWF. Steve English from UK Met Office issue made us aware of a
switch of antenna pattern correction performed February 23 2000. On
this occasion, the antenna pattern correction for the F14 and F15 were
set to match that for the F13 SSM/I. This does not interfere with the
present study period of IOMASA. The data can be unpacked using
standard BUFR libraries and DMI can provide unpacking binaries for SUN
and Linux. Each SSM/I BUFR message contains one scanline of data
organised as follows:
