Giovanni Ocean Color Time-Series Online Visualization and Analysis
| Warning: | September 2009: Due to ocean color data file changes in the most recent reprocessing of SeaWiFS and MODIS Aqua ocean color data by the OBPG, data updates have ceased in this older Giovanni instance. The new data will appear in the Ocean Color Radiometry instancei; because the extensive changes to the data files require significant alterations to Giovanni, this update will be delayed due to the limitations on GES DISC resources which can be dedicated to this effort.

OBPG MODIS-Aqua Monthly Global 9-km Products
This interface is designed for visualization and analysis of the OBPG MODIS-Aqua Monthly Global 9-km Products. Users can generate plots or ASCII Output for area average (Area Plot), time series (Time Plot), and Hovmoller diagram. The animation is available only for Area Plot. Selecting here or the Help buttons will open a new window with detailed help. More details about the data are also available.
Alert: A new window may be opened when a link or a button is selected below.

Data Description
OBPG MODIS-Aqua Monthly Global 9-km Products
The data products available for analysis are 9-km spatial resolution MODIS Aqua monthly SMI (Standard Mapped Image) products from the Ocean Biology Processing Group (OBPG). These data products are generated with data processing methods similar to those applied to SeaWiFS and are not the same as the standard MODIS Aqua products archived by the GES DISC DAAC (see http://oceancolor.gsfc.nasa.gov/ for more information). Four of these products are ocean products: chlorophyll a concentration, diffuse attenuation coefficent at 488 nm, normalized water-leaving radiance at 551 nm, and sea surface temperature. Two of the products are atmospheric products: Angstrom coefficient 531-869 nm, and aerosol optical thickness at 869 nm.
