The NOAA Weather and Climate Toolkit Steve Ansari, Stephen Del Greco, Neal Lott (NOAA / NCDC) 1

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 Smoothed NEXRAD Reflectivity Data 6

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 • Internal Google Earth Instance: (Currently Windows Only) 9

Visualization Hurricane Andrew: NCDC Grid. Sat Climate Data Record (CDR). 10

Visualization • Math tool (max, min, avg, abs max, sum) (Under ‘More…’ link on ‘Data Selector’ or ‘Grid Properties’) 11

Visualization • Experimental Time Morphing (Under ‘Tools’ menu) – Interpolation of data between time steps based on storm motion. – Based on Face Morphing algorithms (javamorph) – Storm motion data from NEXRAD Level-III products, RUC model or manual entry. – Many possible future applications. 12

Visualization • Experimental Time Morphing menu) (Under ‘Tools’ Example Movies: Moore, OK 1999: orig. / morph Fairview, AL 2011: orig. / morph Surry, VA 2011: orig. / morph Western NC 2012: orig. / morph Pierce City, MO 2003: orig. / morph GOES Satellite IR: orig. / morph 13

Community-focused Plugins • IMPACT: Integrated Marine Protected Area Climate Toolkit – specialized user interface prototype built on top of WCT. 14

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) 15

Applications GOES Satellite Imagery from Hurricane Rita landfall, exported as ASCII GRID, in Arc. GIS 16

Applications GOES Satellite Imagery from Hurricane Rita landfall in Google Earth 17

Applications • 3 D Radar Sweeps in Google Earth: – Drapes rendered image on COLLADA model (Similar to 3 D building models) 18

Applications • 3 D Isosurfaces in Google Earth: – Output of 3 D Polygons to KMZ • Supported for Generic Radial, Level-II NEXRAD and Gridded x, y, z datasets. Play Movie 19

Applications Command-line batch processing of data export 20

Applications Public domain / open source API 21

Future Work • Improved Point and Time Series (station data) support. • Comparison between station data and grid/radial data. • More COLLADA work? Cross-sections? • Enhance Time Morphing features. • Batch / Command-line KMZ export. • Enhanced integration with the Climate Services portal (http: //www. climate. gov). 22
