How will Geospace Respond to a Changing Climate?

Co-leaders:

  • Jan Lastovicka (CZ)
  • 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 (storm tracks, mountain waves, convection and stratospheric heating rates).]]

  • Project leaders:
  • Project members:

[[Project 1.2 Changes in filtering (changes of background winds due to CO2 trends and ozone layer changes).]]

  • Project leaders:
  • Project members:

[[Project 1.3 Changes in MLTI dynamics and composition.]]

  • Project leaders:
  • Project members:

Project 2 The enhancement of the anthropogenic effect on the ionosphere/thermosphere during a quiet sun period.

  • Project leaders:
  • Project members:

Project 3 PMC/NLC altitude, frequency and brightness changes related to changes in dynamics and chemical composition.

  • Project leaders:
  • Project members:
