AB: HDFLook is a new multifunctional data processing and visualization tool developed to work with MODIS Land, Ocean and Atmosphere, and AIRS HDF-EOS products. Features include: (1) accessing and visualization of all swath (Levels l and 2) MODIS and AIRS products, and gridded (Levels 3 and 4) MODIS products; (2) re-mapping of swath data to a world map; (3) geo-projection conversion; (4) interactive, batch mode and operational processing capabilities; (5) subsetting and multi-granule processing; and (6) data conversion from HDF-EOS to ASCII, binary, JPEG, GeoTIFF. The versatility of HDFLook resulted in the integration of the tool in several Goddard Earth Sciences (GES) Distributed Active Archive Center (DAAC) subsystems for data distribution and production. HDFLook is the backend engine for the GES DAAC MODIS Ocean Level 2 on-demand parameter subset system. Further, the tool is used for the on-the-fly spatial subsetting of the MODIS Ocean Level 3 gridded data from the GES DAAC Data Pool. The MODIS browse images (Level 1B true-color for daytime, and brightness temperature for nighttime), available for quick review under EOS Data Gateway and GES DAAC Search and Order, are routinely generated by HDFLook as part of the GES DAAC production system. HDFLook future applications include generating daily global MODIS images and backend engine for MODIS L3 Atmospheric products Online Visualization System (MOVAS). HDFLook for AIRS and MODIS is the result of a joint collaboration between the GES DAAC, Laboratoire d'Optique Atmosph‚rique (LOA), University of Lille, France and University of Maryland/ MODIS Land team.It is based on the Motif Satellite Process Handling Images under XWindows (MSPHINX) system, and works on all major Unix/Linux/Mac/Win platforms. It is free and available from the NASA GES DAAC web-site http://daac.gsfc.nasa.gov/MODIS/HDFLook and LOA http://www-loa.univ-lille1.fr/Hdflook/hdflook_gb.html
