“Argentine Network for Upper Atmospheric Research”

Grant: CONICET, Res: 2339/2011. (2011-2013). Director: Dr. Claudio BruniniSite: www.conicet.gov.ar

Objectives:

Promote collaborations among Argentine researchers, educators and students, in scientific and technological research targeted to the studies of the upper atmosphere.

The collaborations will contribute to the formation of human resources and take full advantage of the existing and planned measuring capabilities, including deployed instruments and facilities.

and its impact on ionospheric variability”

Czech Director: Dra. Dalia BuresovaArg. Director: Prof. Marta Mosert

The main aim of this project is to examine the contribution of AGWs excited by meteorological processes to ionospheric variability and energy balance of the ionosphere.

The experimental part of the project consists predominantly in collecting, manual checking and analysis of data obtained from ionosonde and Doppler network, microbarographs and GPS.
