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

2 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 (NetCDF for Java, Common Data Model, etc…)

3 Data Raw data files on disk or remote location (URL, THREDDS, OPeNDAP, etc…) NetCDF, 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.

4 New Features Math Tool Time Morphing GHCN-D export to Shapefile Isosurface export to KMZ (Google Earth) New Feature

5 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)

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

7 Visualization Smoothed NEXRAD Reflectivity Data

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

9 Visualization Sea Surface Temperature (NetCDF data over OPeNDAP)

10 Visualization Internal Google Earth Instance: (Currently Windows Only)

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

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

13 Visualization 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. New Feature

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

15 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 NetCDF, GeoTIFF and KMZ (Google Earth)

16 Data Export Tool to export NCDC GHCN-D dataset (Global Historical Climatology Network - Daily) from NCDC Climate Data Online to Shapefile. New Feature

17 Applications GOES Satellite Imagery from Hurricane Rita landfall, exported as ASCII GRID, in ArcGIS

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

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

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

21 Applications Command-line batch processing of data export

22 Applications Public domain / open source API

23 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 (
