8.3.1.7.3 Data Records

This section describes the data records for both NOAA KLM (version 2) and NOAA-N (Version 3) satellites. Version 2 formats (v2) were used on all NOAA KLM data until April 28, 2005. After this date, the Version 3 format (v3), also known as the NOAA-N format, was implemented for all operational POES spacecraft. On January 25, 2006, Version 4 (v4) was implemented to reflect the start of CLAVR-x (Cl ouds from AV HR R E x tended cloud mask) processing which began on that date. Note: even though there is no AMSU-B instrument on NOAA-N, it's Level 1b format is being updated for consistency with the other instruments' formats, which are also being updated at this time.
