Abstract. Unmanned Aerial Systems (UASs) are increasingly being used as observation platforms for atmospheric applications. The Lower Atmospheric Process Studies at Elevation – a Remotely-piloted Aircraft Team Experiment (LAPSE-RATE) in Alamosa, CO, USA during July 14th–20th, 2018 investigated and validated different UASs, measurement sensors and setup configurations. Flight teams from the Finnish Meteorological Institute (FMI) and the Kansas State University (KSU) participated in LAPSE-RATE to measure and investigate properties of aerosol particles and gases in the lower atmosphere. During the experiment, the performance of different UAS configurations were investigated and confirmed to operate reliably resulting in a scientifically sound observational dataset. As an example, concentration of aerosols – including two new particle formation events, CO2 and water vapor, and meteorological parameters in the atmospheric vertical profile were measured during the short experiment. Such observations characterizing atmospheric phenomena of this specific environment would have not been possible in any other way, and thus, demonstrate power of UASs as new, promising tools in atmospheric and environmental research.

Short summary
This manuscript summarizes the small UAV measurements by the Finnish Meteorological Institute and Kansas State University teams done during the LAPSE-RATE campaign that took place in the San Luis Valley of Colorado during the summer of 2018. We provide an overview of the rotorcraft deployed, insight into the types of payloads, describe scientific goals and flight strategies. The manuscript presents observations of atmospheric thermodynamics, aerosol and gas parameters in vertical column.
