RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations, translates to lightning flash in Spanish and Portuguese) is a collaborative project funded by the US National Science Foundation (NSF), National Oceanographic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), Servicio Meteorologico Nacional (SMN), Ministry of Education, Science and Technology of Argentina (MinCyT), Province of Cordoba, Brazil (INPE, CNPq, and FAPESP), and INVAP, S.E. to observe convective storms that produce high impact weather in the lee of the Andes mountains in Argentina. RELAMPAGO Extended Observing Period will be 1 June 2018 – 30 April 2019, while the Intensive Observing Period will be 1 November – 18 December 2018.

CACTI (Clouds, Aerosols, and Complex Terrain Interactions) is a US Department of Energy (DOE) funded project to study orographic clouds and their representation in multi-scale models for 1 September 2018 – 30 April 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.
