TPOS 2020 at the American Geophysical Union Fall Meeting

Abstracts Due: Wednesday, 29 July 2020

Two AGU sessions on Tropical Pacific research and observations are now open for abstracts on the AGU webpage. Abstracts will be accepted until July 29, 2020. Please be aware that AGU will be held virtually from 1-17 December 2020 and registration fees will be 50% less than the cost for an in-person meeting.

Please contact the lead conveners ( or if you have any questions or visit the AGU Fall Meeting website.

Session Title: Towards improvement in process understanding and modeling of the Tropical Pacific

Session ID: 104660
Section: Ocean Sciences
Conveners: Sandy Lucas, Aneesh Subramanian, Billy Kessler, Ariane Verde

Session Description:
The Tropical Pacific Observing System (TPOS) has been delivering measurements to researchers and a wide range of stakeholders since the 1980s. The primary stakeholders for TPOS are the international science community and national and international prediction centers that provide forecasts of El Niño Southern Oscillation (ENSO). TPOS also serves several other key stakeholders for monitoring the carbon inventory and climate change; managing sustainable fisheries; forecasting weather; and sea level for Pacific island nations and beyond. Several pre-field campaign modeling and process studies are underway to inform the requirements for an observation and modeling process study in the Central and Eastern Tropical Pacific. This session seeks presentations that underscore the fundamental science that will inform the process studies envisioned by TPOS; discuss advances in modeling capabilities and relevant field campaign facilities for TPOS 2020; and highlight the use of TPOS data and prospective products for improved process understanding and model improvement.

Session Title: Application of In Situ and Remote Sensing Technology to Understanding Tropical Pacific Climate Variability

Session ID: 104749
Section: Ocean Sciences
Conveners: Cheyenne Stienbarger, Chris Fairall, Carol Anne Clayson, Nadya Vinogradova-Shiffer

The Tropical Pacific interannual and decadal variability is dominated by the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) and significantly impacts global weather and climate, including Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, ocean carbon outgassing and uptake, and global land temperature patterns. Recent activities in the tropical Pacific, including the redesign of the Tropical Pacific Observing System (TPOS) and the NASA SPURS-2 field experiment, have considered new technologies and novel applications of observing-based knowledge to advance our understanding and prediction of tropical Pacific variability. This session seeks presentations that highlight the application of technologies, including platforms, sensors, and novel analysis of existing observing techniques, both in situ and remote, with the potential to detect, monitor and attribute changes in the physical and biogeochemical systems of the tropical Pacific to our understanding of outstanding questions in tropical Pacific climate variability.
