David Herring Kevin Ward M a y 2 2, n a s a e a r t h o b s e r v a t i o n s (n e o)  Easy access to NASA remote sensing imagery  Designed for educators, communicators, & citizen scientists  Why visit NEO? Obtain Earth images for articles, posters, kiosks, etc. Access data & analytic tools for educational lessons Export images to geobrowsers (e.g., GoogleEarth, WorldWind) Export images for display in virtual globes (e.g., Magic Planet, Science on a Sphere) Browse scenes and then order matching data

Select a subject of interest (e.g., “Ocean”) to see a list of available data sets. Click on one to display it. Note that after the data set loads, there is also a “Search Results” set shown below for the entire archive of that particular data set. Navigation & selection tools.

GES DISC Semi-automated harvesting of recent regional & global data products from multiple data providers MODIS Teams’ Computing Facilities NSIDCICESat Query & retrieve via Web Map Service (WMS) Three vectors for search & retrieval Can view, re-size, re-color, &/or reformat Get image / save locally Export to GoogleEarth Export to Image Composite Explorer Download matching data (in HDF format) Export comma separated values to MS Excel Coming soon: data set comparisons & animate Coming soon: pixel trends over time Middleware with functionality “spokes”

Java-based tool called Image Composite Explorer (ICE) allows for graphical & numerical analysis of data sets. Easy, on-the-fly export to geospatial data browsers, including GoogleEarth & NASA’s WorldWind. Easy export to widely-used tools

 Spatial resolutions 1-km, 5-minute granules Global-scale products at 0.1 degree (3600 x 1800 pixels) & 0.25 degree (1440 x 720 pixels) Platte Carre (cylindrical) is our preferred projection  Temporal resolutions 1 day, 8 or 16 days, 1 month  File format 8-bit binary number arrays, grayscale for products Natural color is the exception Users have the option of accepting our palettes, or devising their own NEO image file specifications

 Atmosphere Data Products Aerosol optical thickness Cloud fraction / cloud mask Aerosol particle size Cloud particle radius Water vapor Cloud optical thickness Carbon monoxide Cloud water content TRMM precipitation Stratospheric ozone TRMM precipitation anomaly UV surface exposure AIRS methane AIRS nitrogen dioxide  Ocean Data Products Sea surface temperature (day) Water-leaving radiance AMSR-E SST SST anomaly SST climatology Chlorophyll concentration NOAA bathymetry Chlorophyll anomaly Sea ice extent Eutrophic depth = products in hand= products near at hand= products planned, but may lag some months NEO’s archive of data sets

 Land Data Products Land cover classification USGS land topography Daily surface reflectance Land snow cover Land in true color Land in false color Ice sheet elevation (Antarctica & Greenland) Global fire maps Vegetation index Snow water equivalent Permafrost extent Land surface temp (day & night) Albedo Leaf area index Net Primary Productivity  Energy Data Products Reflected shortwave radiation Outgoing longwave radiation Net energy flux  Life Data Products Chlorophyll concentration Chlorophyll anomaly Land cover classification Human population density Leaf area index Carbon metabolism (land & ocean) = products in hand= products near at hand= products planned, but may lag some months NEO’s archive of data sets

 Other data sets of possible future interest Landsat LCDF regional & individual band data MODIS individual band data Goddard Modeling & Assimiliation Office (GMAO) data sets (~50 parameters at half-degree resolution)  Future activities Refine & simplify NEO interface Re-design ICE interface to integrate with NEO Conduct usability study of interface Merge NEO and Earth Observatory back-end –Make content “browse-able” by other interfaces, i.e., WorldWind Partner with & EdGCM Develop on-line Amateur’s Guide to Earth Observation Educator-driven evolution: teacher workshop & on-line teacher feedback What’s next…?
