## Motivation

- 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

## Giovanni:  GES DISC Interactive Online Visualization ANd aNalysis Infrastructure

- 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

## Area plot

- _Animations__ _display successive
- area plots

- Time -
- series

- Hövmoller plots

- Overlay Plots

## X-Y scatter plots

- (here, SST vs. chlorophyll)

- Multiple data product
- time-series
- (here, SST vs. chlorophyll,
- in a Giovanni output figure
- adapted for publication)

## NEONASA Earth Observations

- 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

## Examples of NEO visualizations

- Scatter Plot

- Transect Plot

- Histogram

## Philosophy

- Many educational and scientific organizations have created excellent, sophisticated “end-to-end” lesson plans using remote-sensing data
- 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 education *

## AND it should be easy for them to do that!!

- 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 better.

## 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

## Organization

- 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

**The Introduction to **
**each recipe states**
**which data sets and **
**visualizations will be**
**used, and provides**
**a visual and numerical**
**(lat/lon) location **
**guide **

- Location Guide

## Example:  East Australia Current

**Giovanni area plots of **
**Sea Surface Temperature**
**and**
**Chlorophyll Concentration**

**Chlorophyll Concentration plot**
**utilizes the**
**Customized Color Scale option **

## Example:  East Australia Current

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

- Java applet allows interactive transect plot drawing

- Transect plots show fronts
- and eddies clearly

- EAC Front

- Northern
- eddy

- Southern
- eddy

## Development Plan

-  The current Giovanni-NEO oceanographic instructional cookbook is a demonstration prototype
-  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
