Focus Groups provide a home for scientists engaged in research that cuts across two or more AGU Sections. All Focus Groups are charged with:
Atmospheric and Space Electricity focuses on exploring electrical phenomena in the atmosphere and exosphere from the perspectives of plasma physics, space science, middle-atmosphere science and traditional atmospheric electricity.
The Cryosphere Focus Group encompasses the scientific study of the portion of the Earth's surface where water is in a solid form; this includes ice sheets, glaciers, sea ice, freshwater ice, snow, and frozen ground (or permafrost).
The Earth and Space Sciences Informatics (ESSI) Focus Group is concerned with issues of data management and analysis, large-scale computational experimentation and modeling, and hardware and software infrastructure needs, which ultimately provide the capability to change data systems into knowledge systems that support the range of Earth and space science interests.
Global Environmental Change addresses large-scale chemical, biological, geological, and physical perturbations of the Earth's atmosphere, ocean, land surface, and hydrologic cycle with special attention to time scales of decades to centuries and to human-caused perturbations.
Mineral and Rock Physics fosters a focus on the properties of the Earth's materials and their current physical state and chemical makeup as well as the processes that have governed their evolution.
Near-Surface Geophysics focuses on the development and application of any and all geophysical methods to study the near-surface region (top ~100 m) of Earth to advance the fundamental science of geophysical imaging (data acquisition, inversion, interpretation) and to address key questions about subsurface properties and processes.
Nonlinear Geophysics fosters a focus within AGU on the general area of nonlinear geophysical systems, including mathematical and theoretical geophysics, complex systems, and nonlinear processes such as chaos, nonlinear waves, solitons, turbulence, cascades and vortex dynamics, and time series analysis.
Paleoceanography and Paleoclimatology focuses on understanding the past conditions and dynamics of Earth’s oceans and atmosphere and their interactions.
Study of the Earth’s Deep Interior (SEDI) focuses on understanding Earth’s structure at depths inaccessible to direct sampling in order to address fundamental questions about the origin, evolution, composition and dynamics of our planet.
