  • Cryosphere and Climate

    The term “cryosphere” collectively describes elements of the Earth system containing water in its frozen state. It includes snow cover and solid precipitation, sea ice, lake and river ice, glaciers, ice caps, ice sheets, permafrost and seasonally frozen ground. Ice shelves and icebergs are included in these categories. Read More
  • Atmosphere, Oceans and Climate

    The atmosphere plays a key role in the energy balance of the Earth. Read More
  • Water, Energy and Climate

    Solar energy is the fundamental driver of the Earth’s climate system, while infrared emission is the system coolant. Net heating in equatorial regions and net cooling in polar regions drive both atmospheric and oceanic circulations. Read More
  • Atmospheric Chemistry and Dynamics

    The chemistry and dynamics of the stratosphere and troposphere, and their wide ranging interactions, are increasingly being included in the global models used to project changes in climate. Read More

TPOS2020Opportunity to review the future Tropical Pacific Observing System design 22.08.2016

The Tropical Pacific Observing System (TPOS) aims to meet the observational, experimental, and operational needs of today and the future. The purpose of the TPOS 2020 project is oversee the transition to a more resilient and integrated observing system to meet the identified gaps as well as future needs as they are identified. On the TPOS 2020 website a first draft of the future TPOS design is now available, together with a spreadsheet where you are invited to make comments. All comments are due by 23 September 2016.

Please share this report with stakeholders of TPOS observations. If you have distribution lists or specific communities that you think would be interested, please share the link to the report directly, or let the Steering Committee know by This email address is being protected from spambots.

SPARC landscape colourWCRP/SPARC workshop "Challenges for Climate Science - Synergies between SPARC and the WCRP Grand Challenges" 22.08.2016

31 October to 1 November 2016

Berlin, Germany

WCRP and SPARC welcome scientific contributions related to the Grand Challenges on “Clouds, circulation & climate sensitivity”, “Climate extremes”, “Near-term climate prediction”, and “Carbon feedbacks in the climate system” and/or the SPARC themes “Atmospheric dynamics and predictability”, “Chemistry and climate”, and “Long-term records for climate understanding”. The aim of the workshop is to discuss the state of the science in the areas of Grand Challenges and SPARC themes, to define improved collaborations between SPARC and the Grand Challenges and to discuss the role of SPARC and Grand Challenges in WCRP priorities. For more information see the SPARC announcement. The deadline for abstracts and registration is 30 September 2016.

The Mystery of Carbon Tetrachloride 14.07.2016

The seventh SPARC science report on 'The Mystery of Carbon Tetrachloride' is now available! Find the full report here.

The report helps answer policy-relevant questions related to the global budget of carbon tetrachloride, an important ozone-depleting substance; closing the gap between emissions reported to UNEP's ozone secretariat and those estimated from atmospheric observations.
