Clouds, Aerosols, and Complex Terrain Interactions (CACTI)

Adam Varble and Joseph Hardin

Breakout Description

This session overviewed the recently completed Cloud, Aerosol, and Complex Terrain Interactions (CACTI) ARM field campaign. CACTI involved deployment of the first ARM Mobile Facility (AMF1) and CSAPR2 between October 2018 and April 2019 to the Sierras de Cordoba mountain range of central Argentina. The G-1 aircraft gathering measurements on 22 flights between November 4 and December 8. CACTI objectives include quantifying the sensitivity of orographic cumulus, congestus, and deep convective cloud processes and properties to surrounding environmental thermodynamic, kinematic, and aerosol conditions. One particular focus was on deep convective initiation and upscale growth controls that were frequently observed during the experiment.

Main Discussion

Since CACTI recently finished, this session focused on highlighting measurements, products, and science of potential interest to the community. Adam Varble gave a high-level overview of the field campaign including motivation, objectives, measurements, and possible science that can be done with the data. This was followed by an overview of the radar operations and data collected given by Joseph Hardin. Alyssa Matthews then highlighted measurements collected by the G-1 aircraft. Adam Varble presented Steve Nesbitt’s talk on the RELAMPAGO field campaign, and Scott Collis showcased some of the CACTI value-added products that are in the works. After each presentation, time was set aside for discussion, although very few questions and comments were made.

Future Plans

A session will likely be proposed for the 2020 ARM-ASR PI Meeting that will include talks on preliminary science results within the community and encourage collaboration between different groups where possible.
