The GES DISC and the Earth Sciences Division
  Office of Outreach have created two powerful
  online data analysis tools that can be applied to
  remote sensing data
… using nothing more than a Web browser!

Our motivation is to facilitate the use of these
 tools by educators (and students), and also by
 the scientifically-minded public

The main components of Giovanni are:

    interactive map for region-of-interest selection;
    menu of available data products;
    calendar menu for time-period selection;
    menu of visualization options;
    visualization-specific options (color palette, axis values);
    menu of output options

The main components of NEO are:

 Data file selection interface – global, multiple datasets
 Search interface
 ICE (Image Composite Editor) which allows:
   True-color & false color composites
   Scatter plots or graphs of transects
   Histogram analyses
   Probe function: find unit values and lat-lon info per pixel
   Animate time-series images
   Perform math functions
   Zoom & pan
   Assign color palettes

Many educational and scientific organizations have
 created excellent, sophisticated “end-to-end”
 lesson plans using remote-sensing data
                            Sometimes these lesson plans
                            are a less-than-perfect fit for
                            what’s being taught

Our philosophy is to provide educators* with a
 “pick-and-choose” resource that can be easily
 integrated into existing lesson plans or courses
 of instruction – which will also foster skill
 building with the Giovanni and NEO tools

* and the public, providing informal environmental research and
Surmounting the barrier of established curricula in
             classroom instruction!

Skilled researchers and teachers who have taught courses
for many years know what works, and they cover the
material they have determined to be necessary.

Adding something “new” like Giovanni and NEO usually
requires replacing an instructional element that has
functioned well with something as good – preferably

AND it should be easy for them to do that!!
Question: What is needed to facilitate Giovanni and NEO
implementation in oceanographic education?

Answer: A cookbook – providing “recipes”
for the investigation of a multitude of regions and
oceanographic processes.

A skilled chef – the classroom instructor – can select
the appropriate recipes which satisfy the
educational requirements of a particular course.

A recipe would indicate the data products, visualizations,
regions, time periods, etc. to produce the desired output –
which the student interprets.
        Components of the Giovanni-NEO
            Instructional Cookbook
   Introduction
How to use it; what the data products mean; what
  scientists are interested in; data quality concerns
   Functions
Instructions on creating the basic visualizations and
  analyses in Giovanni and NEO
   Recipes!
Step-by-step presentations for creating visualizations and
  analyses appropriate for region or topic - EXPANDABLE
   Additional Information
Resources (“high-quality” links) providing investigational
  opportunities, expanding the range of knowledge
Each recipe chapter will be organized
 as Local – Regional – Global topics.

This organizational strategy facilitates
 connectivity between the observing
 environment of the users
 (teachers/students/public) with the
 larger-scale “view from space”
 provided by remote sensing data
              Example: East Australia Current

                                Location Guide
The Introduction to
each recipe states
which data sets and
visualizations will be
used, and provides
a visual and numerical
(lat/lon) location
            Example: East Australia Current

                                 Giovanni area plots of

utilizes the
Customized Color Scale option

NEO: Side-by-side chlorophyll and sea surface temperature transect analysis

                                              Transect plots show fronts
                                              and eddies clearly

                                                    EAC Front
                                                                eddy       Southern

                                    Java applet allows interactive transect plot drawing
         Development Plan
 The current Giovanni-NEO oceanographic
 instructional cookbook is a demonstration

 A workshop (April-May) at GSFC will
 refine the concept and objectives;
 attendees will be scientists, data
 specialists, formal and informal educators

 The cookbook will be expanded into
 multiple discipline areas
                Take a look!
just Google “Laboratory for Ocean Color Users” !
