The NOAA MODIS/Near-Real-Time System

The NOAA/NESDIS NANOOK (North American Near-real-time-processing Of land, atmosphere, and Ocean Kolor) system will provide the National Weather Service with near-real-time (within 3 hrs of data acquisition) land products as well as atmosphere and oceanic products from the MODIS instrument aboard the Terra satellite. MODIS (Moderate Resolution Imaging Spectroradiometer)is a new instrument that has a greater spectral and spatial resolution than previous instruments.

NANOOK was designed under the Computer Sciences Corporation (CSC) Central Satellite Data Processing (CSDP) contract. The areas of interest for NANOOK include the continental United States, Alaska and Hawaii. The design and operation of NANOOK involved the collaboration with EDOS (EOS Data and Operations System) for satellite data, NASA Goddard DAAC for input ancillary data products, and NASA Goddard MODAPs (MODIS Adaptive Processing System) for processing software.

This paper and presentation will discuss the constraints on near-real-time products including: the hardware system requirements, the independent software development, the porting and integration of the NASA software to the NOAA near real-time environment, the streamlining of existing NASA software, the acquisition of input ancillary data files, and product generation processes.
