The Aviation Digital Data Service (ADDS) is a free public service produced by the
National Center for Atmospheric Research (NCAR) with funding provided by the FAA's Aviation Weather Research Program (AWRP) and the NextGen Network Enabled Weather (NNEW) program.
The ADDS websites result from the dedication of a handful
of scientists and engineers at NCAR and
ADDS was born out of the
RAP weather web site, originally created by
NCAR meteorologist Greg Thompson in the 1990s.
For several years, the site was deployed exclusively at NOAA's
Aviation Weather Center (AWC) in Kansas City, MO. In 2003, the AWC
site was designated as "Operational ADDS" and a new
"Experimental ADDS" site was created at
NCAR. Since then, new research and technology
has been demonstrated first on Experimental ADDS,
before being transferred to Operational ADDS.
- Experimental ADDS
This is not the Operational ADDS website. It is located at
All of the products on that website have been approved as "Operational" by the FAA
and the NWS and may be used as supplementary information for flight planning.
The Operational ADDS website
is monitored by NOAA staff 24 hours a day, 7 days a week.
It is deployed in 3 separate geographic locations across the United States for load balancing and redundancy.
As a measure of its reliability, the Operational ADDS website was certified by the
FAA in 2009, as a Qualified Internet Content Provider (QICP).
The Experimental ADDS website is the one you are currently viewing.
Many of the products on this site are identical to those on the Operational website, but others are next-generation
products in the process of being certified "Operational" by the FAA.
The FAA Aeronautical Information Manual,
states that experimental products should not be used for flight related decisions.
Experimental ADDS is operated by the ADDS
development team at the National Center for Atmospheric Research (NCAR) in Boulder, CO. The site is designed with load balancing and
redundant hardware to be extremely reliable, but it is NOT guaranteed to be available 24 hours a day, 7 days a week.
Experimental ADDS is only monitored by staff during normal business hours
and is only installed in a single geographic location. In the event of the loss of our data feed, a massive equipment failure,
or damage to the building infrastructure, the site could be unavailable for an extended period.
Please use Experimental ADDS for our innovative services, but do not rely on us as
your sole source of aviation weather.
The Experimental ADDS team is comprised of the following individuals.
Arnaud has been developing decision support systems for over 15 years for such varied domains as
aviation, surface transportation, wind energy, and riverbasin management. His passion is improving
how people interact with information to accomplish their work.
Minna joined the ADDS team from
NOAA in the late spring of 2010, where she worked on
NNEW (Next Generation Network Enabled Weather) and the Text Data Server.
Paddy likes METARs, PIREPs, holding hands, and long walks on the beach. He does not enjoy writing short bios about himself.
Aaron is a software engineer who primarily works on the ADDS
Text Data Server and Java displays. He enjoys thinking about thinking about recursion.
