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
