Scientific Commission A: Space Studies of the Earth's Surface, Meteorology, and Climate

Scientific Commission is comprised of a Task Group on GEO and three subcommissions, A1 on Atmosphere, Meteorology and Climate, A2 on Ocean Dynamics and Productivity and A3 on Land Processes and Morphology.

Chair:
Kahn, R. (USA), 2016 – 2020
Vice-Chair:
Benveniste, J. (ESA/ESRIN), 2016 – 2020
 
Intercommission/Panel Liaison:
Scientific Commission C: Nakamura, T. (Japan), 2010 – 2014 (nakamura at rish.kyoto-u.ac.jp)
Scientific Commission C: von Savigny, C. (Germany), 2010 – 2014
Panel on Capacity Building: Kahn, R.A. (USA), 2008 – 2012
 

Terms of Reference

The principal goal of the Commission is to promote and enhance effective international co-ordination, discussion, and cooperation in areas of studies of the lower atmosphere-ocean-land system, where space observations can make unique and useful contributions. The immediate objective is to accelerate the progress in our understanding of the various physical, geochemical and biological aspects in the atmosphere and oceans and on the Earth’s surface using space capabilities. The three particular areas of concern are covered by the three Sub-Commissions. Particular emphasis is given to problems of developing countries.

The Sub-Commissions conduct special studies and publish appropriate reviews or technical reports, etc., organize symposia and special meetings to discuss relevant results, plans and opportunities for observational possibilities, and identify problems of current scientific interest and human importance that are ready for technological exploitation. They may also establish ad hoc task groups for carrying out any of these responsibilities.

Sub-Commission A1: Atmosphere (including Troposphere and Stratosphere), Meteorology, and Climate

Chair:
von Savigny, C. (Germany), 2016 – 2020*
Vice-Chairs:
Kalashnikova, O. (Russia), 2016 – 2020*
Kasai, Y. (Japan), 2016 – 2020
 

Terms of Reference

COSPAR Sub-Commission A1 promotes research and international cooperation in the area of space borne remote sensing observation with applications in climatology, meteorology, climate monitoring, surface processes and biosphere monitoring. It also supports the development of new space borne remote sensing technologies by providing an international forum for discussion and coordination.

The goals are mainly achieved through:

  • the organization of symposia and workshops at the regular COSPAR Scientific Assemblies;
  • the support and sponsoring of special workshops on relevant themes;
  • the editing and publishing of scientific papers presented at the COSPAR Scientific Assemblies. These papers appear in the COSPAR journal Advances in Space Research.

The Sub-Commission also provides, on request, reviews or technical reports of current activities in the area of space borne remote sensing to international organizations such as the United Nations.

Sub-Commission A2: Ocean Dynamics, Productivity and the Cryosphere

Chair:
Lee, T. (USA), 2016 – 2020
Vice-Chairs:
Ebuchi, N. (Japan), 2018 – 2022
Kostianoy, A. (Russia), 2018 – 2022* (kostianoy – at – gmail.com)
 

Terms of Reference

This sub-commission’s role is to promote and encourage research activity and international cooperation in physical and bio-geochemical oceanography and in the cryosphere. Over the last 25 years these domains have passed a major turning point thanks to the arrival of new measurement techniques on-board satellites. The global and accurate view of the ocean and the cryosphere, acquired from many space missions used synergistically, has permitted a better understanding of the various mechanisms involved and their role in the Earth system. But studies and joint efforts are still needed at international level, to continue to improve our knowledge. Topics of particular interest, and requiring international cooperation, are:

  • The determination of mass, heat transport and fluxes over the ocean and their interaction with atmosphere.
  • The development of new space-based techniques to monitor surface and subsurface parameters of the open ocean and the coastal zone, as well as freshwater fluxes to the ocean.
  • The joint use of satellite, in situ data with models to provide analysis and forecasts of the ocean in 3D.
  • The preparation of future global ocean observation systems for monitoring the ocean circulation, its variability and the sea level trends (global and regional).
  • The carbon cycle in the ocean, the biological processes, and their impact on climate, biogeochemical cycles and productivity.
  • Cryospheric studies: ice sheet and mountain glaciers mass balance, sea-ice thickness and extent, snow depth and extent.

Sub-Commission A3: Land Processes and Morphology

Chair:
Muramatsu, K. (Japan), 2018 – 2022
 
Vice-Chairs:
Dash, J. (UK), 2018 – 2022
Guo, L. (China), 2018 – 2022
 

Terms of Reference

This Sub-Commission aims to develop a better understanding of biosphere, including artificial changes of the land surface (both physical and biological), and interactions of land surface with atmosphere, with due emphasis on the application of active and passive sensors’ data having varied spatial and temporal resolutions acquired from satellites. The processes of interest include heat, water, and carbon balance. The Sub-Commission will remain abreast of the advances in and endorse and encourage calibration and intercalibration of sensors for quantitative monitoring and quantifying changes in the Earth system.
