Level 1B Product Information and Status

The Level 1B Code generates data products containing calibrated radiances for all 36 MODIS bands and reflectances for the reflective Solar bands (Bands 1 through 19 and 26). The MODIS Terra L1B Version 3.0 and higher software is considered validated.

Collection 5 processing is ongoing and  is producing Level 1B products. Collection 6 processing will begin approximately late April 2012.  There will be an initial period during which both Collection 5 and Collection 6 products will be available.

Using the PGE02 version 5.0.6.34 LUT in MODAPS production, a Terra Level 1B data processing failure occurred on day 2007-09-17 at 19:35UT when the linearly-interpolated RVS_correction values for Band 8 fell below a hard-coded limit.  SeaWiFS production encountered the same problem starting on 2007-09-18 at 09:45UT. A code fix was implemented as version 5.0.38 and data production was resumed during the evening on 2007-09-20.
