Clouds, Aerosols, and Complex Terrain Interactions (CACTI)


We’re interested in what are the atmospheric
processes that determine whether deep convection is going to initiate or not. These are things that we have to represent
in climate models and right now it’s done in a rather crude fashion and we have a lot
of regional climate biases because of that. CACTI is a campaign that’s very heavily
focused on clouds and aerosol data, and how that relates to the storms that we observe
here. There’s two components to it. One is the AMF site. It’s really nice to have, sort of a long-term
field site component to complement the mobile operations that are happening through RELÁMPAGO. And in addition to that, they are also deploying
the DOE G1 which is a research aircraft. We have cloud radars. We have also aerosol instruments. We have radiometers to measure solar radiation. We have a met station with radiometers, anemometers. We have to be able to measure winds, temperature,
relative humidity, pressure. We also measure the properties of clouds,
cloud microphysics, aerosols, trace gasses. The hope is that we can build up a really
large dataset such that we can differentiate between various factors that impact deep convection.
