Title: Sample Data Interactive Publication:
1Sample Data Interactive Publication
- Interactive access, analysis and display of
remotely stored datasets from a convective rain
event over Colorado
Ben Domenico Jeff Weber Unidata Program
Center Boulder, CO
This material is based upon work supported by the
National Science Foundation.
2Objectives
- Make scientific data an integral part of the
digital libraries and the World Wide Web - Enable readers of scientific publications to
interact directly with datasets referenced in the
publications - Facilitate the creation of educational modules
with embedded tools that allow learners to work
directly with authentic scientific datasets.

- As Hurricane Charley approached the Florida
coast, it amplified from a category 2 storm at
1300Z to a category 4 storm at 2000Z
(landfall). This view displays in 3-D, the iso
surface of wind speeds of 18 m/s (36 mph) from
1200Z on the 13th to 1200Z on the 14th. The
display also includes wind vectors at the 500
millibar level. The US coastline is highlited in
white, and the u component of the 10 meter winds
is displayed in a contour plane view. This is
output from a workstation_eta model run over the
Florida domain. To view this via the IDV select
this link Workstation Eta - Hurricane Charley's rainfall was greatest near
the eyewall, this dataset of Base Reflectivity
from Tampa Bay starting at 1301Z to 2022Z,
shows the intense banding as it comes ashore. The
temporal resolution begins at every 15 minutes
and goes to every 5 minutes starting at 1900Z.
Of course once you load the bundle, you can
manipulate the times and duration as you desire,
this is the power of a compund interactive
document. To view the Tampa Bay radar products

13Challenges
- Agreed-upon protocols for data access (e.g.,
OPeNDAP, ADDE, WCS) - Catalogs of data on remote servers (e.g.,
THREDDS, CSW) Discovery and usage metadata - Persistent storage on server sites or
- Not everyone has ability to create own permanent
case studies collections - Mechanism for invoking local application from web
page (e.g., agreed upon mime-type)
