three near-real-time systems: the GES DISC AIRS and MLS systems, the
OMI SIPS system, and this system. LANCE-MODIS provides certain Aqua
and Terra MODIS L0, L1, L2, L2G, and L3 products on a near-real-time
basis. On average, the L1 and L2 products are available within 2.5
hours of the observation time. LANCE-MODIS has two standalone
systems to improve availability. Data products may be accessed from
the FTP sites of either

10.18.13 - The LANCE-MODIS backup system will be shut down on
Wednesday, October 23, 2013 from 7am to 8am EDT for scheduled
maintenance. During the down time, the
http://lance2.modaps.eosdis.nasa.gov/ web site will not be available.
The nrt2.modaps.eosdis.nasa.gov FTP site will be available, but the
data will be delayed because the processing server will be down. The
primary system will be available as usual during the down time. We
apologize for any inconvenience this may cause.
10.16.13 - Due to the unavailability of the NSIDC Near-Real-Time Ice
and Snow Extent (NISE) product after October 6th, some MODIS products
may experience a small quality degradation. The NISE product is used
by Atmospheric algorithms (Cloud Mask, Cloud Properties) to
characterize the surface where snow cover strongly alters the
seasonal surface albedo. In using out-of-date NISE data, MODIS data
product degradation is expected to be small, where fresh snow for
instance in the northern hemisphere may not be accurately modeled.
Such conditions may lead to a higher number of failed retrievals of
cloud properties in MOD06_L2 and MYD06_L2.
10.09.13 - We are unable to produce the MxDAODHD products because
production requires an ancillary product from GMAO, which is down
due to the government shutdown. We will let you know when this data
is once again available. We apologize for any inconvenience this may
10.09.12 - The Naval Research Laboratory and the University of North
Dakota developed a value-added aerosol optical depth dataset based
on MODIS Level 2 aerosol products. The NRL-UND product is a level 3
gridded product specifically designed for quantitative applications
including data assimilation and model validation. This dataset has
been given the ESDT identifier MxDAODHD
