NASA MODIS Rapid Response System

The MODIS Land Rapid Response system has been developed to provide rapid access to MODIS data globally, with initial emphasis on 250m color composite imagery and active fire data. This research and development system is a contribution to the rapid prototyping of NASA's Applications data and information systems, providing data and information in support of decision making. The system builds on the experience gained with the MODIS Land 250m production and distribution system. The data delivery system is also being developed as a contribution to the implementation of the international Global Observation of Forest Cover/Global Observation of Landcover Dynamics (GOFC-GOLD).

The MODIS Land Rapid Response imagery augment the MODIS Standard Land Products, which can be obtained from the EDC DAAC. Availabilty of MODIS Standard Land Products will lag behind current satellite acquisition by a few days but all the data used to create images in the Rapid Response System are available from the GSFC DAAC (Level 1b data) or the EDC DAAC (Active Fire - MOD 14).

MODIS Level 0 data are obtained through the NOAA MODIS Near Real Time Processing System NASA/GSFC. They are processed to L1B data using the IMAPP software distributed by the University of Wisconsin. L1B data are then processed to L2 and L3 products using rapid response code specifically developed for this application.

Gallery images can be viewed as JPEG images in pixel sizes of 1 km, 500m or 250m. A flash-based interactive viewer (FSI) is also available. Near-real-time images are available in pixel sizes of 4km, 2km, 1km, 500m, and 250m.
