BEAM Software: The Basic ERS & Envisat (A)ATSR and Meris Toolbox (BEAM) is a collection of executable tools and an application programming interface (API) which has been developed to facilitate the utilisation, viewing and processing of ESA MERIS, (A)ATSR and ASAR data. It can be downloaded fee of charge. SeaDAS (SeaWiFS Data Analysis System) is a comprehensive image analysis package developed by NASA's Ocean Biology Processing Group (OBPG) for the processing, display, analysis, and quality control of all SeaWiFS data products. It is freely available for download. SeaBatch - If you work with ocean colour data and utilize SeaDAS (see above), you likely need a way to batch process multiple files. SeaBatch can help. SeaBatch is a group of Unix shell scripts that batch process ocean colour data derived from NASA's MODIS (Aqua and Terra) and SeaWiFS sensors. With SeaBatch you can: Process MODIS Level-0 files (utilize high-resolution bands) Process Level-1 files to Level-2 Spatially bin Level-2 files (.5, 1, 2, 4, 9, and 36 km) Temporally bin Level-2 files (day, 7day, 8day, and month) Output Level-3 files as ascii, flat, hdf, png, etc. SeaBatch is a powerful tool that will greatly assist you with your research. It is free, as are SeaDAS and Unix. If using runtime SeaDAS, an IDL license is not required. Borstad Associates Satellite Image Toolbox. Free on-line tools and re-assembled datasets to help generate and test ideas, and to facilitate use of remotely sensed imagery in support of oceanographic and limnological research. Most of the datasets focus on the Canadian West Coast, but a very useful 'Temporal Profiler' is available for the entire North West Hemisphere. ArcGIS & satellite data - Importing satellite data into ArcGIS just got easier! There is now an ArcGIS extension that allows users to browse THREDDS catalogs and connect directly to OPeNDAP servers to access large amounts of scientific data and ingest the data into ArcGIS desktop 9.3. This extension, called the Environmental Data Connector (EDC), uses a Java-based browser and leverages existing components from Unidata and NOAA/PMEL libraries so that users can filter large amounts of data in space and time. The user has a choice of importing the data into ArcGIS in either raster or feature format. The time stamped data can then be animated using a TimeSlider extension which is built into the EDC. A stand-alone version is also available, which provides a GUI to browse THREDDS catalogs or OPeNDAP directories, to subset the selected data in space and time, and to download the data as a netcdf file. The EDC was developed for NOAA Fisheries by Applied Science Associates, Inc. with funding from NOAA’s Satellite Research and Operation (R&O) project, and is freely available at www.pfeg.noaa.gov/products/EDC/. A patch that affects the handling of files within ArcGIS (not necessary for use with the standalone version of EDC) is available from the same website.

Software for Graphics and Data Analysis Software for the calculation of surface solar irradiance and PAR, using SeaWiFS data - written by Robert Frouin and John McPherson. WIM (Windows Image Manager) is a general-purpose image display and analysis programme for various satellite images, including those from ocean colour sensors (see http://wimsoft.com). This is commercial software, but it is available for free evaluation. A major addition to the tools is the WIM Automation Module (WAM), which allows automating repetitive tasks by writing simple programs using WIM functions e.g. calculating primary production according to Behrenfeld-Falkowski model. ACRI-ST of France has developed several tools for the commissioning phase of the ENVISAT MERIS and GOMOS instruments. Details are available at http://www.acri-st.fr/tools/ Additional useful links for analysing satellite data can be found on the data processing and analysis webpage of the "Marine Environmental Protection of the Northwest Pacific Region" website.
