This presentation will describe and demonstrate (via the Internet) interactive Java-based viewing tools that have been developed for the Aviation Digital Data Service (http://adds.aviationweather.noaa.gov/). These tools include "viewers" for aviation forecasts (e.g., AIRMETs and Convective SIGMETs) and aviation-relevant observations (e.g., PIREPs and METARs). Also included is the ADDS Flight Path Tool that enables users (such as pilots and airline dispatchers) to generate interactively for user-specified flight routes time-sequenced vertical and horizontal graphical cross-sections of forecasts and observations.

The presentation will also address the technical challenges the ADDS Team faced in developing tools that respond quickly to user requests. And it will address how ADDS tools may benefit surface transportation.

ADDS is being developed by the NCAR Research Applications Program (RAP), NOAA Forecast Systems Laboratory (FSL), and NWS Aviation Weather Center (AWC) under the auspices of the Federal Aviation Administration (FAA) Product Development Team for Aviation Forecasts and Quality Assessment Funding is provided by the FAA Aviation Weather Research (AWR) Program.
