Decoding ERS FD LBR Data from WMO FM BUFR format

Purpose of the BUFR software (UNIX and VMS versions)

The ERS-2 Low Bit Rate Fast Delivery products are transmitted over the WMO GTS ( World Meteorological Organisation Global Telecommunications System) using a special Buffer format WMO FM94 BUFR.

The products transmitted with this BUFR format are:

  • the ERS-2 UWA: SAR wave fast delivery product
  • the ERS-2 URA: altimeter fast delivery product
  • the ERS-2 UAT: ATSR fast delivery product (suspended)
  • the ERS-2 UWI:  Wind Scatterometer fast delivery product

Software changes applied on version 5.03 (September 2001)

  • Support for the new ATSR-2 ASST (UAT) products processed by the SADIST-2 software. Limiting/scaling of the ATSR accross-track band number, with reduced resolution on decode, has been implemented to fit to new SADIST-2 processor specification.
  • Support for WMO/GTS RMDCN protocol

Software changes applied on version 5.01 (January 2000)

  • Implementation of the latest WMO BUFR standard known as Edition 3. This mainly defines additional information in the BUFR message header section and includes the latest WMO published look-up tables.
  • Support for the ATSR-2 ASST (UAT) product processed by the SADIST-2 software.
    Recently implemented at the Tromsoe receiving station and now available to ESA for dissemination along with the other ERS Fast Delivery Products, the SADIST-2 products - different from earlier SADIST V600 products - have actually required changes of the BUFR specification for this data type.
  • Tables amendments to support for QuikSCAT products decoding.
  • Year 2000 compliance

Software features in version 4.04 (Dec 98)

  • Wet tropospheric correction flag implemented in the ESA decoded URA product in the DSR (Data Set Record) field 18, bit 1 (as defined in the document "ERS Ground Stations Products specification", with reference ER-IS-EPO-GS-201, issue 3/1, dated December 9 1994).

IMPORTANT:
Users should upgrade their decoders when ATSR products (UAT) will be distributed by ESA

You will be informed by means of this web page or through our Helpdesk.
The Version 5.01 can be still used to decode the others data (UWA, URA, UWA) encoded with Version 5.03.
The Version 5.03 will however transparently decode messages encoded with the old versions of the encoder.
