The data sets provided by Concordiasi will result in collaborative efforts into satellite data
assimilation, Antarctic precipitation and the interplay between polar stratospheric clouds, gravity waves,
vortex dynamics and ozone depletion. Concordiasi being part of the IPY, data will be provided freely, as
soon as possible after measurement and quality control, with a delay of typically 6 months and a maximum
delay of two years.
Some data will be available with restricted use, before they are considered fully validated.

Access to the data are conditioned by the respect of the Acknowledgement sentence below and
an acknowledgement to the PI providing the particular data set used: "Concordiasi was built by an international
scientific group and is currently supported by the following agencies: Météo-France, CNES, IPEV, PNRA,
CNRS/INSU, NSF, NCAR, Concordia consortium, University of Wyoming and Purdue University. ECMWF also contributes
to the project through computer resources and support, and scientific expertise. The two operational polar
agencies PNRA and IPEV are thanked for their support at Concordia station. Concordiasi is part of the
THORPEX-IPY cluster within the International Polar Year effort."
Moreover, specific access to the driftsonde data will be conditioned by the addition of the following
Acknowledgement sentence: "The driftsonde data have been obtained through a cooperation between UCAR
and CNES, under the sponsorship of the NSF and the CNES."
