The history files include code changes to calibration code written for MODIS/AQUA and MODIS/TERRA respectively and also changes made to common MODIS/TERRA/AQUA code predating the split in code application made in February 2002. The history file for MODIS/AQUA does not include changes made to MODIS/TERRA-specific code after February 2002. The same applies to the history file for MODIS/TERRA which does not include changes made to MODIS/AQUA-specific code after February 2002.
