The SPARC (Stratosphere-troposphere Processes And their Role in Climate) 2014 General Assembly was held on 12-17 January 2014 in Queenstown, New Zealand. It was the fifth gathering of 300 SPARC scientists from around the globe. General Assemblies are opportunities for SPARC to take stock of what has been achieved, where gaps in the portfolio of research undertaken by SPARC need to be filled, and to define where SPARC needs to be moving to remain responsive to the needs of both its members and the users of SPARC research products.

Sponsors
As with previous General Assemblies, we offered financial assistance to support the attendance of PhD students, early career scientists, and scientists from developing countries or countries in transition.
Sponsorship received for the conference was channeled into providing financial support to mitigate registration, travel and accommodation costs for these delegates.
We had four levels of sponsorship for the SPARC 2014 General Assembly:
Platinum NZ $50,000
Gold NZ $20,000
Silver NZ $5,000
Bronze <NZ $5,000
We are pleased to report that this sponsorship allowed us to provide partial or full funding support to 83 scientists. This was a significant portion of the attendees at the SPARC 2014 General Assembly, and it was great to be able to facilitate their attendance in this way. Our sincere thanks go to all of our sponsors.
