How will Geospace Respond to a Changing Climate?

- Daniel Marsh (USA)
Introduction
Scientific issues
Task Group 2 will focus on answering these three key questions over the next 4 years:
1. How do changes in tropospheric wave generation and their propagation through a changing atmosphere affect the dynamics of the MLT?
2. By how much is the anthropogenic effect on the ionosphere/thermosphere enhanced during a quiet sun period?
3. Are PMC/NLC characteristics trending?
To answer these questions, five projects are established characterize and understand the impacts of:
Project 1.1 Changes in wave sources
[[Project 1.1 Changes in wave sources (storm tracks, mountain waves, convection and stratospheric heating rates).]]
- Project leaders:
- Project members:
Project 1.2 Changes in filtering
[[Project 1.2 Changes in filtering (changes of background winds due to CO2 trends and ozone layer changes).]]

Project 1.3 Changes in MLTI dynamics and composition

Existing work and plans
The 6th IAGA/ICMA/CAWSES workshop on “Long-Term Changes and Trends in the Atmosphere” (http://www.hao.ucar.edu/TREND2010/index.php) will be held at National Center for Atmospheric Research (NCAR) Center Green Conference Center, Boulder, Colorado, USA, June15-18, 2010, the week before the 2010 CEDAR (Coupling, Energetics, and Dynamics of Atmospheric Regions) workshop, which will also be held in Boulder.
