Lunar calibration enhancements for MODIS collection 7

MODIS on board the Terra and Aqua spacecrafts have been in operation for 22 and 20 years, respectively. Throughout each mission, Moon observations have been a key component to the on-orbit calibration. For MODIS Collection 7, we have updated the lunar calibration algorithm to provide improvements to the data quality. This includes removing pixel oversampling errors associated with including partial lunar images in addition to full disk images, data masking for the mitigation of crosstalk contamination, and corrections to digital counting errors (sticky bins). These corrections reduce variations in the data while maintaining the long-term trends from Collection 6.
