Historically SPARC concentrated on the role of the stratosphere in climate, but now includes foci throughout the atmosphere in recognition of the latest research, which clearly calls for a "whole atmosphere" approach.

The new SPARC implementation plan 2016-2020 is organised around three refined scientific themes and a number of current and future activities of which many reflect the more regional focus and interdisciplinary nature of SPARC research.

The CLIVAR Early Career Scientists Symposium takes place on 18 and 24-25 September 2016 before and after the CLIVAR Open Science Conference which will be held in Qindao, PR China.

Early Career Scientists Symposium

The Early Career Scientists* Symposium (ECSS) is a 3-day programme designed by, and for, early career scientists. It is a unique opportunity for young scientists with outstanding research potential to interact and exchange ideas with their peers and senior scientists on what is required to better understand aspects of the climate system and address research challenges of societal relevance. An ambitious agenda is being developed to engage the ECS in the science topics addressed in the OSC, discussing the future of international efforts to address critical science needs, considering current pressing scientific and related societal challenges. The ECSS will include career development workshops, as well opportunities for the participants to discuss their scientific achievements, while building lasting relationships and collaborations with colleagues from different countries. To apply for a place at the Symposium, participants must submit an abstract as first author to the main conference, and indicate that they would like to take part in the Symposium. Those selected to attend the ECSS will be notified at the end of May 2016.

* ECS are defined as students or those researchers within 5 years of their most recent degree.

Travel Grants

Limited resources are available to support attendance of researchers from developing countries and early career scientists. Financial assistance can be requested only via the conference website on submission of an abstract. Deadline for requests is 15 March 2016. Participants requesting support will be notified of the availability of funds in May and June.

Session AS13:
Interaction of Atmospheric Composition and The Asian Monsoon

Conveners:
Hiroshi Tanimoto (NIES, Japan), Nguyen Thi Kim Oanh (AIT, Thailand), Manish Naja (ARIES, India), Jim Crawford (NASA Langley, USA), Laura Pan (NCAR, USA)

Session Description:
Monsoon Asia is a “frontier” of atmospheric science, and a variety of research programs are emerging with a great emphasis on the climate impact of regional emissions, air quality, and biogeochemical cycles and their coupling with monsoon dynamics. Increasing levels of trace species in the presence of high water vapor and intense solar radiation are raising the importance of understanding the physical, dynamical, and chemical processes over this region. Specific focus areas in this session include

1. emissions and air quality such as changes in atmospheric composition due to anthropogenic, biomass burning, and biogenic emissions,
2. chemistry-climate interactions such as aerosols and clouds in the Asian monsoon region, interplay of Asian monsoon convection and atmospheric chemistry, and UTLS response to the Asian monsoon,
3. the impacts of air quality on health and vegetation, and
4. biosphere-atmosphere interaction.

Both observational and modeling studies on these topics in the Asian Monsoon region are invited.

This session also seeks to foster a community of atmospheric composition studies in the Monsoon Asia and Oceania regions through introducing the Monsoon Asia and Oceania Networking Group (MANGO) and the Atmospheric Composition and the Asian Monsoon (ACAM) activity, both sponsored by IGAC and SPARC.
