Welcome to the South America affinity group website. This group was established to accelerate research and discoveries focusing on the water and energy cycle of South America. This effort is led by NCAR's Water Systems program and the Hydrometeorological Applications Program (HAP) and fosters collaborations across NCAR and the international research community. NCAR's role in this project is the development of a high-resolution, convection-permitting modeling system for South America, that enables unprecedented insights into atmospheric and hydro-climatologic processes in South America. NCAR closely collaborates with university patterns in the U.S. and South America and supports international research activities such as ANDEX, which is a prospective GEWEX Regional Hydroclimate Project (RHP).
NCAR is organizing monthly meetings to foster collaborations on key research challenges in South America and to gather feedback on the project's progress and future direction. Agendas and recordings from past meetings can be found under the "Resources" tab.
This page contains meeting minutes and presentation records. The meetings are organized chronologically starting with the most recent on top.
Upcoming meeting
Next meeting: July 29, 2020, 10-11 a.m.
Main focus: Group discussion on the next computer request to NCAR Computer Laboratory to perform the twenty-year historical and twenty-year future simulations at 3 km (PGW?). Need to submit in September 2020.
Video recording (not available)
Many of the regular precipitation and temperature observations in South America are operated by governmental institutions dedicated to water management and forecasting operations. We have gathered some of the publicly available data and combined them with the global datasets that are available in this region.
A summary of observations datasets in South America is published in Condom et al. (2020).
The following table summarizes observational datasets in South America. For further information contact Lucia Scaff (lucia.scaff@usask.ca) or Kyoko Ikeda (kyoko@ucar.edu).

In preparation for the ANDEX RHP, a series of research articles was published in a special issue in Frontiers on the topic of "Connecting Mountain Hydroclimate Through the American Cordilleras".
This is an NCAR lead effort to establish a GEWEX Regional Hydroclimate Project over the United States. More information can be found in an article that by Schneider and van Oevelen published in GEWEX News Vol. 30, No. 2 | Quarter 2, 2020
