1. Survey for the field experimentCollect existing met/hydro information through the region in preparation for the field experiment.Points of contact to find out availability of data (coordinator: Marcelo Seluchi): -
Argentina: Hydro - Carlos Paoli (Santa Fe) / Met -
Olga Penalba
- Bolivia: Hydro - Edgard Montenegro (Tarija) / Met - name to provided by Meitín - Brazil: Hydro - Walter Collischonn / Met - Marcelo Seluchi - Paraguay: Hydro/met Roger Monte Domecq - Uruguay: Met - Rafael Terra 2. Establishing a representative "supersite" for LPBTo
determine an appropriate site to centralize
hydro/met observations for
a broader community.
Hydrology and meteorology working together Location? Foz do Iguazu - triple border transition area between monsoon and tropical systems, very intense rain activity. No radar coverage Important the size of the supersite, Oklahoma example (square of 100 km) Hydro differences between sides of Parana River Must be based on which have already LPB document will provide insight on what we currently have We will have to focus in Paraguay-Brazil border, also Argentina Main idea for a supersite to have as much as possible, weather-hydro stations Some stations from Brazilian Air Force Matogroso do Sul side has almost nothing Parana has very good observation network Argentina has a group of stations downstream of the site Itaipu & Yacireta have their own networks People from Itaipu have expressed strong interest in participate on scientific projects Yacireta contact Lucas Chamorro Two persons from Itaupu at Foz do Iguazu meeting Explore a meeting either at Yacireta or Itaipu 3. Radar integrationA
network of radar systems is being integrated in Southeastern Brazil.
Integration of radars from
Paraguay and Argentina using the same
protocols is an objective.
Procedures to become integrated, need internet connectivity, real-time communication, compatibility. Radar integration network text for: Frederico Angelis Paraguay contact Miguel Vazquez Argentine Air Force offer to become part of the network. Buenos Aires (SMN) Pergamino (INTA) NCAR/EOL has a portable radar could be available for the experiment, find the best location Season for the experiment 5 to 6 months starting September. NCAR radar available for some 3 weeks, one year before has to be defined, proposed, approved. Sept 2009- March 2010 Coordinated observations needed For the experiment, show regional model improvement with the existing radar data What is the spatial and temporal scale for the experiment? The experiment is not limited to the supersite. Take into consideration winter LLJ and MCS activity but the gap between systems is large - need good operational network for long term monitoring Find people interested in inter-seasonal studies 4. Flux TowersTo
select 1 to 3 flux towers to be used as reference sites representative
of LPB for
CEOP.
contacts: Otávio Acevedo (Brazil), Steve Williams (US) 5. Soil moisture measurementsTo
obtain soil moisture
observations for model calibration and other
agricultural purposes.
Assunção (Javier, Angelica) Javier Tomasella (CPTEC), Rafael Terra (Uruguay), Armando Brizuela (in situ), Angelica Giarolla (satellite, aircraft) 6. DeadlinesDeadline of contributions to LPB implementation Plan, October 30. Late November a meeting with European partners for future joint proposal Next LPB Group meeting late Feb 2007, early March in Buenos Aires Deadline IAI - NCAR - EU proposals IAI will help to support next LPB meeting (Argentine debt) EU April 2007 NCAR proposal request - May 2008 (January 2008) - for a campaign in Nov 2009 - March 2010 7. ModelingThe
issue on climate change scaling scenarios on LPB document is missing
-
Vicente Barros will help
Educational outreach and political implications need to be part of a proposal Membership of LPB implementation steering group, need to reshape 8. Next meetingsChange
of the name
of the group:
It was concluded that the name ISG does not fully represent the scope of activities of the group leading LPB, and thus it was decided to rename it - February 2007 LPB SISG meeting in Buenos Aires - September 2007 meeting in Yacireta/Itaipu - VAMOS meeting 2 April 2007 (Chile) - endorsement of LPB - PLATEX Chairs (Higgins, Marengo) of VAMOS to receive a report form LPB co-chairs Climate change scenarios - Vicente Barros Model intercomparison - Pedro Silva Dias (section 9.5) Work in a better model for climate change scenarios: Systematic errors, basic errors on physics (excess rainfall in western Argentina...) Issues for next meeting:
