ADDS - Aviation Digital Data Service


Effective Thursday, June 30, 2016 at 1500 Coordinated Universal Time (UTC), 11:00 a.m. Eastern Daylight Time, the legacy Aviation Weather Center webpages listed at http://www.aviationweather.gov/info/legacy, and Java applet-based webpages at https://www.aviationweather.gov/adds will no longer be publicly accessible.

If a user attempts to access these webpages after this date/time, automatic redirects will occur. This change is required since the Java applet will no longer properly function with Java Release 9. As the Java applet has evolved, its Application Programming Interface (API) has also changed, to the point where it can no longer be reliably used since it significantly degrades Web browser performance and must be deprecated.

If users still desire to use Java-based functionality, please visit the Flight Path Tool application: https://www.aviationweather.gov/flightpath Otherwise, users can access a variety of OpenLayers GIS applications readily available at: http://www.aviationweather.gov For more information, please view the complete Service Change Notice (SCN) at: http://www.nws.noaa.gov/os/notification/scn16-10java_legacy.htm

Java Tools


 
example new flight path tool

Flight Path Tool Application

This tool provides all of the features of the old Flight Path Tool applet and more. It still allows you to view data along your route of flight. You can still view icing, turbulence, temperature, winds, humidity, AIRMETs, METARs, TAFs, etc. both horizontally and vertically. Now, however, you get many more features not available in the applet. In the future, we'll be adding even more features to the application but not to the applet. Take a look.
 
example NCWF applet

NCWF Java Tool

The National Convective Weather Forecast (NCWF) product contains a convective hazard detection and 1-hour forecast. The current hazard field is colored green to red for increasingly strong convection and the 1-hour forecast hazard region is outlined with cyan polygons.
 
example METARs applet

METARs Java Tool

The METARs Java Tool allows users to view METARs graphically and textually at the same time with only the variables that you desire. You can zoom into particular regions, turn on temperature, weather, and winds, check ceiling height and visibility. The tool is remarkably configurable.
 
example TAFs applet

TAFs Java Tool

This tool provides users with a quick interface to retrieve text-format Terminal Aerodrome Forecasts (TAFs) for a particular region. Simply zoom into your flight area and quickly read the TAFs for departure, destination, and alternate airports.
 
example PIREPs applet

PIREPs Java Tool

The PIREP Tool allows users to view PIREPs graphically and textually at the same time and provides map overlays and zooming capability. You can also remove displayed PIREPs for particular altitude ranges if, for instance, you do not care about turbulence above 20,000 feet.
 
example AIRMETs applet

AIR/SIGMETs Java Tool

The AIR/SIGMETs Tool allows users to view AIRMETs graphically and textually at the same time and provides map overlays and zooming capability. You can also remove displayed AIRMETs for particular altitude ranges if, for instance, you do not care about icing above 14,000 feet.
