UPDATE EDITION!  2016 Natal (Brazil) Data Is Posted!                                                                  03/10/2016 – 00:27

The long-awaited, promised calendar year 2016 ECC Ozonesonde vertical profile data for the Natal, Brazil, site is now available. This data is made available after intensive meta data and data review, assessment, and requisite editing of processing control parameters. The data set comprises 44 balloon flights that have either been reprocessed or are newly processed using the latest UAIRP flight data reduction program. This data supersedes and replaces any previously generated and archived data products for 2016 from the Natal site. The INPE Natal station site releases instrument packages consisting of a GPS radiosonde and an ECC ozonesonde on a nominal weekly basis. Natal is a cooperating SHADOZ observing station operating under a joint NASA-INPE agreement. Hardware and processing support are provided by SHADOZ at Goddard and UAIRP at Wallops under funding from the NASA Headquarters Upper Atmosphere Research Program.

IMPORTANT NOTICE!  Data Files Contain Precise Balloon Release Location!                                 12/20/2016 – 04:13

Effective 12/20/2016: processed ECC Ozonesonde instrument flight data will contain the GPS-determined precision balloon release location latitude, longitude, and station height in the metadata header rather than some generic or table lookup site location reference. This change will apply to processed data forward as well as to any reprocessed prior flight data sets.

EARLY EDITION!  UAIRP Wallops Ozonesonde Data Now Up-To-Date for 2016!                              12/06/2016 – 18:36

The Wallops ECC Ozonesonde instrument balloon flight data set for 2016 is now current through the latest flight vertical profile.
It is our intentional purpose and goal to post current Wallops flight data within 24 hours after actual flight termination within the Monday–Friday work week, with exceptions for federal holidays and weekends.

EXTRA! EXTRA!  UAIRP Wallops Ozonesonde Data Now Available!                                                 11/29/2016 – 23:27

After a lengthy hiatus, since late July 2016, due to problems with data reduction processing and file server network communications, followed by upgraded security measures incorporated in the Code 610.W web server platform prohibiting web page content update, the data processing and posting of output data has been restored!

A new processing program for ECC ozonesonde data reduction has been installed, tested, and is now operational.

Shortly, the 2016 balloon profile data backlog for the INPE station at Natal, Brazil, will begin processing, and these flight data sets will be posted as completed.

Welcome to the “new” UAIRP Internet web site!  [Updated 09/08/2017]                                   08/04/2016 – 18:00

This is your link to Upper Air Instrumentation Research Project (UAIRP) data. Data is made available from nominal weekly flights of ozonesonde instrument balloons from NASA’s Wallops Flight Facility at Wallops Island, Virginia USA, as well as, from the INPE Natal, Brazil, site operating under a joint NASA-INPE cooperative agreement. [INPE is Instituto Nacional de Pesquisas Espaciais, the Brazilian National Institute for Space Research.]

While data is routinely posted to the Network for Detection of Atmospheric Composition Change (NDACC) [operated by NOAA’s National Weather Service] and the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) [operated by the Government of Canada for the World Meteorological Organization (WMO) Global Atmospheric Watch (GAW) Program], data collected from Wallops Island balloon releases is generally posted within 24-48 hours after the flight. Vertical profile flight data from Natal is generally available within one (1) week following the flight.

If you are interested in using data from this web-site would you please be kind enough to drop us an email message with your name, location, email address, and organization [if applicable], along with any pertinent details of how you intend to use this data. All that we might know you better, and that we might communicate with you directly in future.

Please contact the UAIRP Principal Investigator and Technical Monitor Dr. Anne M. Thompson at, or UAIRP Computer Scientist/Engineer E. Thomas Northam at  Thank you.
