International MODIS/AIRS Processing Package

 AIRS L1B HDFEOS to BUFR Format Utility v1.2 Release         24 August 2010

   This package consists of software that will convert AIRS Level 1B Radiance HDFEOS files (AIRS.2009.02.06.176.L1B.AIRS_Rad.v5***.hdf) into Binary Universal Form for the Representation of meteorological data (BUFR) format. The output consists of selected channels at full spatial resolution. The software defaults to selecting the standard 324-channel set, but the user can substitute their own channel selection if you prefer.

The software package includes a main run script, as well as a 32 bit statically linked binary that should execute on most flavors of linux. There is a build script in the main software /src directory that will allow users to build the executable on their own OS/platform.

This software was written by Nigel Atkinson, Met Office, Exeter, UK. The changes to this package from version 1.1 are:

  • AMSU capability:

    Added the capability of reading Advanced Microwave Sounding Unit (AMSU) HDFEOS files (AIRS.2009.02.06.176.L1B.AMSU_Rad.v5***.hdf) and including co-located AMSU temperatures in the AIRS BUFR output. This functionality was implemented by Zhihong Li, Australian Bureau of Meteorology. The second argument to the airs1b_to_bufr.bash script is now the name of the AMSU HDFEOS file. The AMSU channel numbers for BUFR descriptor 005042 run from 1 to 15, in line with the change made by NESDIS in May 2010. HSB channel numbers are set to missing. This software has been tested with the latest versions of BUFR and HDF libraries.
