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.
