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

On Wednesday 2015-08-12 between 8:00 to 12:00 EDT the nrt1 system including ftp site nrt1.modaps.eosdis.nasa.gov will undergo scheduled maintenance and may be unavailable. On Thursday 2015-08-13 between 10 and 12 EDT the nrt2 system will be unavailable.
06.24.2015 Production in the LANCE-MODIS NRT1 system will be down on 2015-07-01 between 14:00 and 16:00 GMT
Production in the lance-modis nrt1 system will be down on 2015-07-01 between 14:00 and 16:00 GMT. Data at nrt1.modaps.eosdis.nasa.gov will be available via ftp during this time, however more recent data may be available at nrt2.modaps.eosdis.nasa.gov until nrt1 production catches up (probably by 18:00 GMT). Likewise production in the lance-modis nrt2 system will be down on 2015-07-02 between 14:00 and 16:00 GMT, with similar latency effects.
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
