We describe accurate measurement of particle formation and growth in the CERN CLOUD (European Council for Nuclear Research Cosmics Leaving OUtdoor Droplets) chamber, using a suite of gas- and particle-phase instruments. The interconnected measurements establish high accuracy in key particle properties and critically important gas-phase sulfuric acid. This is a template for accurate calibration of similar experiments and thus accurate determination of aerosol nucleation and growth rates, which are an important source of uncertainty in climate science.

We performed an extensive closure study including laboratory and simulated experiments to evaluate various angular corrections for the Aurora 4000 polar nephelometer, focusing on irregularly shaped aerosols such as mineral dust. We describe the impact of particle size, refractive index, and shape on the determination of the particle scattering coefficient and propose a guideline to establish the most appropriate angular correction depending on the aerosol type and the investigated size range.

During the A-LIFE campaign in the Eastern Mediterranean, a research aircraft observed clouds in a Saharan dust layer using in situ and remote sensing measurements. With new analysis tools for improved particle sizing and liquid water content measurements, this study assesses two different aerosol-cloud interaction processes: heterogeneous ice nucleation on super-micron dust particles at the cloud top, and small-scale activation of mineral dust particles to liquid droplets within the cloud.

A field experiment deployed in Cyprus included two sun photometers of Aerosol Robotic Network in two different sites. Mineral dust was predominant during the experiment, with Saharan and Arabian dust showing distinct optical properties, in particular, the Angstrom Exponent in the near-infrarred range and Volume Efficiency factor. Both magnitudes can served as a reliable proxy for mineral dust typing. No significant black carbon presence was detected.

Observations show large dust particles travel much further than expected, which is not replicated in weather and climate models. We use a climate model to understand which processes dominantly impact large particle transport, and find that modelled large particle transport agrees with observations best after reducing the particle gravitational settling by ~ 80 %. We prove the presence of processes not represented accurately or at all in the model which act on large particles in the real-world.

The Next Generation of Earth Modeling Systems project (nextGEMS) developed two Earth system models that use horizontal grid spacing of 10 km and finer, giving more fidelity to the representation of local phenomena, globally. In its fourth cycle, nextGEMS simulated the Earth System climate over the 2020–2049 period under the SSP3-7.0 scenario. Here, we provide an overview of nextGEMS, insights into the model development, and the realism of multi-decadal, kilometer-scale simulations.

The A-LIFE aircraft field experiment was carried out in the eastern Mediterranean in 2017. Using A-LIFE data, we studied the change in mineral dust optical properties due to mixing with anthropogenic aerosols. We found that increasing pollution affects dust optical properties, which has implications for identifying dust events and understanding their climate effects. We also show that optical properties of Saharan and Arabian dust are similar when comparing cases with equal pollution content.

Aerosols contribute to the largest uncertainties in climate change predictions. The eastern Mediterranean is a hotspot for aerosols with natural and anthropogenic contributions. We present lidar measurements performed during A-LIFE (Absorbing aerosol layers in a changing climate: aging, lifetime and dynamics) to characterize aerosols and aerosol mixtures. We extend current lidar classification and separation schemes and compare them to classification schemes using different methods.

We tested a method to identify airborne microplastics (MPs), merging imaging, fluorescence, and machine learning of single particles. We examined whether combining imaging and fluorescence data enhances classification accuracy compared to using each method separately and tested these methods with other particle types. The tested MPs have distinct fluorescence, and a combined imaging and fluorescence method improves their detection, making meaningful progress in monitoring MPs in the atmosphere.

Short summary
Large mineral dust particles are more abundant in the atmosphere than expected and have different impacts on the environment than small particles, which are better represented in climate models. We use aircraft measurements to assess a climate model representation of large-dust transport. We find that the model underestimates the amount of large dust at all stages of transport and that fast removal of the large particles increases this underestimation with distance from the Sahara.

Transporting a representative aerosol sample to instrumentation inside a research aircraft remains a challenge due to losses or enhancements of particles in the aerosol sampling system. Here, we present sampling efficiencies and the cutoff diameter for the DLR Falcon aerosol sampling system as a function of true airspeed by comparing the in-cabin and the out-cabin particle number size distributions observed during the A-LIFE aircraft mission.

Biomass burning sulfur dioxide (SO2) emission factors range from 0.27–1.1 g kg-1 C. Biomass burning SO2 can quickly form sulfate and organosulfur, but these pathways are dependent on liquid water content and pH. Hydroxymethanesulfonate (HMS) appears to be directly emitted from some fire sources but is not the sole contributor to the organosulfur signal. It is shown that HMS and organosulfur chemistry may be an important S(IV) reservoir with the fate dependent on the surrounding conditions.

Short summary
Particle number concentration is one of the most important parameters to quantify an aerosol. Aerosol number concentration in the nanometer range is commonly measured with condensation particle counters (CPCs). A CEN technical specification harmonizes the CPC specifications. However, it is not specified for low-pressure conditions as on high mountains or on airplanes. Here, we present the pressure-dependent performance of two different models of CEN CPCs, the Grimm 5410 CEN and the TSI 3772 CEN.
Particle number concentration is one of the most important parameters to quantify an aerosol....
