MODIS Aggregate for the Gulf of Maine; MODIS Ocean Products SST and Chlorophyll-a 8-Day L2 Global 1.25 km Lambert Grid, DOY: 305, 2000 to present

This dataset represents spatial aggregates of a variable number of granules of the MODIS Ocean standard level 2 products that cover the Gulf of Maine. Each product is an 8-day composite, which was derived as the average data value for the 8-day period. If data quality is poor on particular days, the average was derived only from those days having good data. Files containing the number of days used to produce the averages (counts) are included.

The University of New Hampshire's Coastal Observing Center (&http://cooa.sr.unh.edu&) has created this MODIS product from daily chlorophyll-a and MOD28L2 Sea Surface Temperature level 2 granules covering the Northeastern Coastal United States. This MODIS data is provided as 8-day averages for the Gulf of Maine region in the Lambert Conformal Conic projection. UNH has resampled to 1.25 km grid and reprojected the granule data using the SeaDAS software (&http://seadas.gsfc.nasa.gov/&), to make a product which can be spatially subset within the Search and Retrieve data ordering tool

These regional products allow COOA users to subset MODIS 8-day SST and chlorophyll-a data across tile boundaries and to customize the spatial region of interest using an on-line GUI interface.

Data are also provided in HDF-EOS, NetCDF, and a generic binary format (BSQ) with detailed header information, which can be read into most image or data processing applications.
