Description 2016-12-08T02:30:00Z
Aqua L0 data MYD00S between 2016-12-07 11:25 and 12:30z was substantially missing when first delivered and processed by Lance-MODIS causing a few errors and some undersized products. It was redelivered, and we have reprocessed and produced normal sized MYD00F, and downstream products are currently being reprocessed or produced.

These MYD00F granules from yesterday are also missing data. Although redelivered MYD00S probably contains the missing data, we do not plan to reproduce them as no processing errors occurred. Look for the products from forward processing.

There are also some slight issues with MYDGBAD and the PM1EPHND_NRT produced from it:

Reprocessing 20:40-20:49 produced a normal filesize of 20000.

MYD00F was recreated between 2016-12-07 20:30 to 22:10 and was much improved, so downstream products are being reprocessed as well.
