Clouds remain a major source of uncertainty in weather and climate prediction because key processes occur at scales that are difficult to observe. We developed a new airborne measurement system carried by a tethered balloon that directly images individual cloud droplets and their motion. Our field tests demonstrated reliable operation and revealed cloud structure at unprecedented detail, providing a new tool for studying cloud development, rainfall formation, and climate.

During the Pallas Cloud Experiment (PaCE) in northern Finland from September 15 to 28, 2022, detailed measurements of the atmospheric boundary layer, aerosols, and cloud droplets were collected using the Max Planck CloudKite platform, WinDarts, and a ground station. Observations covered altitudes from ground level up to 1.5 km above ground level. This paper presents the dataset, describes the data collection process and structure, and provides guidance for users.

Vertical profiles and time series of aerosol particles, cloud droplets, and weather conditions were measured by the Finnish Meteorological Institute airborne payload attached to tethered balloons during the Pallas Cloud Experiment 2022 in Finland. When combined with other datasets collected during the campaign, these measurements will enable integrated analyses and offer a comprehensive view of the atmospheric conditions during the experiment.

Accurate measurement of cloud particles is crucial for cloud research. While holographic imaging enables detailed analysis of cloud droplet size, shape, and distribution, processing errors remain poorly quantified. To address this, we developed CloudTarget, a patterned photomask that can quantify the detection efficiency and uncertainties. Additionally, our AI-based classification enhances both accuracy and speed, achieving over 90 % precision while accelerating analysis 100-fold.

HoloTrack is a fully autonomous system designed to capture detailed data on cloud droplets. It combines holographic imaging with environmental sensors to measure droplet size, movement, and surrounding air conditions. The system records hologram pairs to track droplet motion. While it can be used in the lab, it is mainly designed for in-flight use to measure cloud droplets in-situ. This paper presents the instrument’s design and evaluates its performance through testing.

Microplastics are transported over large distances in the atmosphere, but the shape-dependence of their atmospheric transport lacks investigation. We conducted laboratory experiments and atmospheric transport simulations to study the settling of commercially sold microplastics. We found that films settle up to 74 % slower and travel up to ~ 4x further than volume-equivalent spheres. Our work emphasizes the role of the atmosphere as a transport medium for commercial microplastics such as glitter.

This work presents an innovative way of sampling and analyzing volcanic clouds using an unoccupied aircraft system (UAS). The UAS can reach hazardous environments to sample volcanic particles and measure in situ key parameters, such as the atmospheric concentration of volcanic aerosols and gases. Acquired data bridge the gap between the existing approaches of ground sampling and remote sensing, thereby contributing to the understanding of volcanic cloud dispersion and impact.

During the Pallas Cloud Experiment (PaCE) in Finland (Sept. 19–26, 2022), the Advanced Max Planck CloudKite instrument (MPCK+) gathered turbulence, wind shear, and cloud data from 0–1200 m. Flights lasted 1.5–3 hours, capturing droplet concentrations and size distributions at high resolution (<10 m spacing). The dataset aids studies of Arctic boundary layer clouds above freezing temperatures. This paper details the data collection, structure, and user guidelines.

Three-dimensional (3D) wind velocity measurements are of major importance for the characterization of atmospheric turbulence. This paper presents a detailed study of the measurement uncertainty of a three-beam wind lidar designed for mounting on airborne platforms. Considering the geometrical constraints, the analysis provides quantitative estimates for the measurement uncertainty of all components of the 3D wind vector. As a result, we propose optimized post-processing for error reduction.

Short summary
The rate at which energy is dissipated in a turbulent flow is an extremely important quantity. In the atmosphere, it is usually measured by recording a velocity time at a specific location. Our goal is to understand how best to estimate the dissipation rate from such data based on various available methods. Our reference for evaluating the performance of the different methods is data generated with direct numerical simulations and in highly controlled laboratory setups.
