WHAT IS RELAMPAGO-CACTI?
RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations, translates to lightning flash in Spanish and Portuguese) is a project recommended for funding by the US National Science Foundation (and is in the facility request/PI proposal stage) and is proposed to NASA/NOAA to bring US resources to the field to observe convective storms that produce high impact weather in the lee of the Andes mountains in Argentina. It will also involve significant contributions from Argentina (CONICET), Brazil (CNPq and FAPESP), and Chile (CONICYT), as well as universities across the region, Argentina’s national meteorological service (Servicio Meteorológico Nacional, SMN) and Brazil’s space agency (INPE) that governs Brazil’s weather and climate prediction service (CPTEC).
CACTI (Clouds, Aerosols, and Complex Terrain Interactions) is a ($7.4 million) funded project to study orographic clouds and their representation in multi-scale models for 15 Aug 2018 – 31 Mar 2019. It will involve the AMF-1 cloud-aerosol-radiation observatory, the Mobile Aerosol Observing System (MAOS), the CSAPR-2 precipitation radar, and a surface meteorological network. It will also bring intensive airborne observations during RELAMPAGO through the deployment of the G-1 aircraft.
