Welcome to the LANCE-MODIS data system operated by the GSFC Terrestrial Information Systems Branch, Code 614.5. LANCE includes 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 system.

Other components of LANCE:

• AIRS, Aura MLS L2 Temperature, and Aura MLS L2 Ozone data products from GES DISC.

• OMI data products from OMI SIPS (contact Curt.Tilmes@nasa.gov to set up a subscription). Data derived from the OMI SIPS data can be found at TEMIS and NOAA NESDIS.

Other near-real-time systems at NASA/GSFC:

• Daily satellite images of the Earth's landmasses from the MODIS Rapid Response System.

• Aqua and Terra MODIS L2 Ocean Color and Sea Surface Temperature data products from OCDPS.

05.14.12 - Due to the MODIS Science Formatter problem, a data loss occurred on DOY 132 13:47:23z through 21:59:17z. As a result, Terra MODIS near real-time granules for 2012-05-11 13:45 through 22:00 UTC will not be produced.
