What is the lag time between observations and the availability of products?

The lag time between observations and availability of products is only a few days. The processing and reprocessing schedule for all MODIS data determines the lag time. Please refer to Data Versions Web page for the processing history and reprocessing schedule.

Lag time may be extended due to satellite maneuvers and extra quality assurance required for the geolocation data after the maneuver. Please see the MODAPS Web sites for information on data outages and satellite maneuvers affecting processing.
