**Multi-Sensor Distributive On-line Processing Visualization and Analysis System Using Giovanni**

** ****Access to data from multiple remote sites as well as local sites**
** ****Server-side temporal and spatial subsetting**
** ****Server-side processing**
** ****Support for multiple data formats including Hierarchical Data Format (HDF), HDF-EOS, network Common Data Form (netCDF), GRIdded Binary (GRIB), and binary.**
** ****Support for multiple plot types including area, time, Hovmoller, and image animation**
** ****Support for outputting data in ASCII format**
** ****Easily configurable to support customized portals for measurements-based projects or disciplines        **

**The ability to use data stored in the current Earth Observing System (EOS) archives for studying regional or global phenomena is highly dependent on having a detailed understanding of the data's internal structure and physical implementation.  Gaining this understanding and applying it to data reduction is a time-consuming task that must be undertaken before the core investigation can begin.  This is an especially difficult challenge when science objectives require users to deal with large multi-sensor data sets that are usually of different formats, structures, and resolutions.  The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has taken a major step towards meeting this challenge by developing an infrastructure that supports a Web interface that allows users to perform interactive analysis online without downloading any data.  The underlying infrastructure that integrates all the components is called GES-DISC Interactive Online Visualization and Analysis Infrastructure or “Giovanni.“  Giovanni provides interactive, online, analysis tools for data users to facilitate their research. **
**From the user's perspective, Giovanni is a simple Web application.  Both ****Java and non Java versions are available.  The user selects one or more ****parameters to display along with the spatial area, the temporal range, ****and the plot type.  Plot types include area, time series, Hovmoller, and ****animation.  ASCII output, appropriate for GIS or other user applications, ****is also available.  The user may also select one of several color options.**

** ****SEAWIFS – monthly global 9-km product**
** ****MODIS – atmosphere monthly global**
** ****TRMM – three hourly, daily, monthly and global**
