Slide1:  Consortium INGV, Rome, ITALY, ISC-CNR, Florence, ITALY, HMO, Hermanus, SOUTH AFRICA University of Bath, UK, University of Calgary, CANADA,Polish Academy of Sciences Warsaw, POLAND Upper Atmosphere Monitoring for Polar Year 2007-2008 (UAMPY): a bipolar consortium within ICESTAR/IHY core project The UAMPY overall aim is to create new international cooperation in ionospheric research to develop polar upper-atmosphere observation networks for: mapping ionospheric features continuously from mid through to polar latitudes making conjugate studies of magnetospheric-ionospheric coupling processes relating the large-scale to the small-scale features, in particular the auroral and polar ionospheric irregularities causing scintillation Potential exists for many new studies with both scientific and practical investigations Slide2:  UAMPY - equipment GPS TEC and Scintillation receivers (50Hz data) in the Northern Europe at the mainland EISCAT sites, Arctic (Svalbard), Canada (CANGIM network), in the Antarctic (MZS, DOMEC, SANAE) and on board of SAAghulas (South Africa). Digisondes, riometers, HF Radar (part of the SuperDARN network in the Antarctic) (SANAE IV, MZS). DomeC To be installed in 2008 Slide3:  Amplitude and phase scintillation indices are derived in real time from the L1 GPS frequency recorded at 50Hz. A new model is under development to forecast the ionospheric scintillations over the poles based on ion density in situ data and tested on experimental TEC and Scintillation data. MIDAS: Multi-Instrument Data Analysis (Un. Bath-UK) generates ionospheric electron concentration movies from GPS differential phase observations. It uses the Weimer model to reconstruct the plasma dynamics. UAMPY – DB & software Slide4:  An example of the UAMPY potentialities (1/2) Plasma dynamics and scintillation event during the Halloween storm (30 October, 2003) as reconstructed by MIDAS (left and bottom-left) and as observed by the GPS scintillation network. Slide5:  De Franceschi G., Alfonsi L., Romano V., Aquino M., Dodson A., Mitchell C.N., Spencer P., Wernik A. W., Dynamics of high-latitude patches and associated small-scale irregularities, JASTP, accepted 2007. An example of the UAMPY potentialities (2/2) Slide6:  WHAT ABOUT OUR NATIONAL ENDORSEMENTS AND FUNDINGS? Italy: Italian Government is evaluating the possibility to provide extra funds (supplementary respect to the ordinary funds for scientific and technological Italian activities) to PNRA (Italian National Program for Antarctic Researches) to support Italian participations to IPY initiatives. The Italian IPY activities are under the supervision of a National Committee (www.annopolare.it). South Africa: The HMO has received from the South African Department of Science and Technology, a copy of a letter from the Minister of Science and Technology of South Africa, Mr Mosibudi Mangena, directed to Dr T Rosswall, ICSU Executive Director, in which the role of the HMO in the proposal 'Upper Atmosphere Monitoring for Polar Year 2007/8' (UAMPY) for participation in IPY 2007/2008 as part of the ICESTAR/IHY consortium has been endorsed. SANAP proposal for participation in ICESTAR/IHY/UAMPY entitled "Polar Space Weather Studies during IPY/IHY" has been accepted on February 2006. Funding for 2006 and 2007 has been approved for most of the proposed activities and one overwintering expedition member for Antarctica for the 2006/2007 period has been allocated, enabling the RSA consortium to play an active role in the International ICESTAR/IPY project during IPY2007-2008. Poland:GPS TEC, scintillation, and irregularity drift measurements are planned to start in summer this year at the Polish Polar Station, Hornsund Fijord, Svalbard. This project has a full endorsement of the Polish IPY Committee. Funding for the project should be provided by the Ministry of Science and Higher Education. The final decision is expected at the end of February 2007. UK:The UK Engineering and Physical Sciences Research Council has provided funding for a research officer to work at the University of Bath in association with imaging the polar cap ionosphere.  The project is funded from 2005-2008 and specifically mentions activities supporting International Polar Year. Canada: Financial support for high-latitude scintillation and TEC studies has been obtained from the Natural Sciences and Engineering Research Council of Canada. This funding is part of a strategic project to model and mitigate impact of scintillations on GNSS operations in Canada during 2006-2009. Slide7:  An example of the UAMPY connection inside ICESTAR: location with SuperDARN fields of view Slide8:  and outside ICESTAR… UAMPY and POLENET: what in common? The huge coverage of GPS receivers planned in the POLENET project could represent an unprecedented opportunity to investigate the ionosphere over Antarctica. From: http://rses.anu.edu.au/~anya/polenet/field_antarctic_gps.htm Slide9:  Kickoff meeting of UAMPY activities: The INGV group decide to use the funds provided by PNRA inside the project "Upper Atmosphere Observations and Space Weather" (Resp. G. De Franceschi) to organize a kickoff meeting in Rome from 21st to 23rd of May 2007. One of these three days will be open to all those groups, that envisaging possible collaborations, are interested to attend the meeting. This will be an occasion of brainstorming to exchange ideas, to plan joint collaborations, to contribute to the ICESTAR (and UAMPY!!) initiatives during the IPY and IHY.

An example of the UAMPY potentialities: a link between ICESTAR and POLENET Slide20:  UAMPY database - in progress Slide21:  Questions to POLENET: Which stations are really there? Which is the latency of the data? Which is the sampling time of the storage? Are they in RINEX format? Please provide details of the characteristics of each receiver, coordinates included. UAMPY proposal: According to the coordinate information given by the POLENET Community the UAMPY team could simulate ionospheric imaging over Antarctica. This will allow assessment of POLENET for actual ionospheric imaging as is already being done for the Arctic.
