Furthering research, exploration, and the peaceful use of outer spacethrough international cooperation
Scientific Commission is comprised of a Task Group on GEO and three subcommissions, A1 on Atmosphere, Meteorology and Climate, A2 on Ocean Dynamics, Productivity and the Cryosphere and A3 on Land Processes and Morphology.

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.

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 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.
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:
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.
