Educational
Best Practices
Color theory and perception: no ROYGBIVs, mostly linear gradients (colorbrewer2.org)
Browser and platform agnostic: works on desktop, tablet, or phone
Simple taxonomy and browsing structure
Pre-rendered and tiled to improve server-client performance
6
the
Assumptions
You don’t know the difference between OI SST, Pathfinder SST, GHRSST or ERSST
You don’t know that a dataset only has a certain lifespan
You don’t want to wait for data to process into imagery
You will come up with more interesting uses for our data than us

Linking to
NGSS
Analyze and interpret data from maps to describe patterns of Earth’s features
Analyzing and Interpreting Data
Represent data in tables and graphical displays to describe typical weather conditions expected during a
particular season.
In many systems there also are cycles of various types
Use and share observations of local weather
conditions to describe patterns over time
Patterns exist everywhere
Stability, change, and cycles
Some kinds of severe weather are more likely than others in a given region. Weather scientists forecast
severe weather so that the communities can prepare for and respond to these events.
Models can be valuable in predicting a system’s behaviors

ARCTIC GREENING
• Seasonal patterns
• Carbon cycle
• Albedo
• Feedback systems
• Climate change
• Future projections using climate models
www.amnh.org/explore/science-bulletins/(watch)/bio/visualizations/greening-of-the-arctic
ARCTIC GREENING ACTIVITIES
Introductory Activity
•Use NOAA View vegetation data at www.nnvl.noaa.gov/#NDVI
•Look at global patterns of greening over annual cycles
•Pick a locale and use the data values tool to graph the changes
over time
•How does greenness change over different latitudes or
biomes or hemisphere?
•Compare different graphs.
Extended Activity
•Choose another dataset in NOAA View (Land Surface
Temperature, Soil Moisture, etc.)
•Plot the patterns for the same location
•How do the plots compare?
•Hypothesize what could cause these similarities, if any.
CORALS & CLIMATE
• Ocean heat engine
• Seasonal patterns
• Climate change impacts
• Adaptation & resilience
• Future projections using climate models
www.amnh.org/explore/science-bulletins/(watch)/bio/visualizations/warm-forecast-for-coral-reefs
CORALS & CLIMATE ACTIVITIES
Introductory Activity
•Use NOAA Coral Reef Watch Google Earth tool to select a reef
•View time series data for reef; explore seasonal patterns and
coral’s adaptive range. Pool class data to compare reefs/ocean
regions.
•Explore when reef crossed bleaching threshold (2010) in graphs
•Compare to spatial datasets (DHW) from NOAAView
•Identify future bleaching projection for reef in AMNH Google Earth
datasets; compare scenarios
Extended Activity
•Ask a research question about coral reefs and analyze data to answer it.
•Example: When might my reef bleach? In Google Earth or NOAAView,
add data values for SST anomalies over bleaching threshold to predict
bleaching. Compare with observed DHW values.

EL NIÑO – LA NIÑA ENSO
• Ocean heat engine
• Atmospheric circulation patterns
• Weather vs climate
• Linkages between land, ocean, and atmosphere
www.amnh.org/explore/science-bulletins/(watch)/earth/visualizations/el-nino-to-la-nina
EL NIÑO – LA NIÑA ACTIVITIES
Introductory Activity
• In NOAA View, look at patters of ENSO using the data at
www.nnvl.noaa.gov/#SSTA (select monthly)
•Step 1: Visually assess how long an average ENSO cycle takes
•Step 2: Use the real-time data in NOAA View to track the
progression of ENSO
Extended Activity
•Pick an ENSO cycle over time (1997-2000; 2007-2008; 20092010)
•Can you track linkages between changes in the ENSO cycle
and other datasets in NOAA View?
•Precipitation: www.nnvl.noaa.gov/view/#GPCP
•Chlorophyll concentration: www.nnvl.noaa.gov/view/#ALGE
•Global surface temperature:
www.nnvl.noaa.gov/view/#GHCN
•Coral Bleaching: www.nnvl.noaa.gov/view/#CDHW
•Hypothesize and research why these linkages may occur.
