Overview • • • Free, public domain source code Desktop and command-line application Simple visualization and data export Platform independent (Java-based) Leverages community tools and standards (Net. CDF for Java, Common Data Model, etc…) 2

Data • Raw data files on disk or remote location (URL, THREDDS, OPe. NDAP, etc…) • Net. CDF, GRIB, GINI, HDF and more via Unidata Common Data Model (CDM): – Feature types of Grid, Swath, Radial (Time Series, Point, coming soon) • Supports: – NEXRAD, GOES, Model Data, and much more. 3

Visualization • Simple 2 -D maps • Basic overlays included (states, counties, etc…) • Background images from any OGC WMS – Shaded Relief, Topo Maps, Landsat, ext… • Save images and animations to Animated GIF, AVI, KMZ (Google Earth) 4

Visualization GOES Infrared Water Vapor with Blue Marble Web Map Service (WMS) background map 5

Visualization U. S. Drought Monitor service from NIDIS/NDMC (National Drought Mitigation Center) 7

Visualization Sea Surface Temperature (Net. CDF data over OPe. NDAP) 8

Visualization Sea Surface Temperature Animation (Net. CDF data over OPe. NDAP) 9

Visualization • New Feature: – Internal Google Earth Instance (Currently Windows Only) 10

Visualization Hurricane Andrew: NCDC Grid. Sat Climate Data Record (CDR). 11

Data Export • “Bridge” between raw Weather and Climate data and multiple scientific user communities • Export Data to: Shapefile, Well-Known Text, Arc/Info ASCII GRID, Gridded and Raw Net. CDF, Geo. TIFF and KMZ (Google Earth) 12

Applications Level-II NEXRAD Reflectivity data from Hurricane Charley in ESRI Arc. Scene. Data exported to a point Shapefile with an exaggerated height attribute. 13

Applications GOES Satellite Imagery from Hurricane Rita landfall, exported as ASCII GRID, in Arc. GIS 14

Applications GOES Satellite Imagery from Hurricane Rita landfall in Google Earth 15

Applications • New Features: – 3 D Radar Sweeps in Google Earth • Drapes rendered image on COLLADA model (Similar to 3 D building models) 16
