Use of an Uncrewed Aerial System to Investigate Aerosol Direct and Indirect Radiative Forcing Effects in the Marine Atmosphere

Abstract. An uncrewed aerial system (UAS) has been developed for observations of aerosol and cloud properties relevant to aerosol direct and indirect forcing in the marine atmosphere. The UAS is a hybrid quadrotor – fixed wing aircraft designed for launch and recovery from a confined space such as a ship deck. Two payloads, Clear Sky and Cloudy Sky, house instrumentation required to characterize aerosol radiative forcing effects. The observing platform (UAS plus payloads) has been deployed from a ship and from a coastal site for observations in the marine atmosphere. We describe here the details of the UAS, the payloads, and first observations from the TowBoatUS Richard L. Becker (March 2022) and from the Tillamook UAS Test Range (August 2022).

Short summary
An uncrewed aerial observing system has been developed for the measurement of vertical profiles of aerosol and cloud properties that affect the Earth’s radiation balance. The system was successfully deployed from a ship and from a coastal site and flown autonomously up to 3,050 m and for 4.5 hr. These results indicate the potential of the observing system to make routine, operational flights from ships and land to characterize aerosol interactions with radiation and clouds.
