Status of Current Operational ProductsThe current Aqua operational products are based on Reprocessing 1. Some of the changes discussed here were put into forward-stream production on 10 June 2005, as the instrument degradation was significantly deviating from the existing model and a quick update was deemed neccessary. Final refinements were completed and the forward stream was updated again on 27 July 2005. A full-mission retrospective processing with a consistent calibration is now underway.
Evaluation of Reprocessing ConfigurationA complete mission reprocessing was performed on a temporal subset consisting of the first 4 days of each 32-day period. A generic discussion of the analysis methods is available here.

The reduction in striping in the derived products can be observed by comparing detector relative trends derived from global analysis of Level-2 match-ups to 7-day Level-3 means. As an example, the comparison of 443nm nLw residuals (%) for a day near the mid-point of the mission is shown below:
