Project description
Study assesses the impact of primary biological aerosol particles on the climate
Primary biological aerosol particles (PBAP) are solid airborne particles derived from biological organisms. Depending on their surface properties, the particles can serve as nuclei for water droplets or ice crystals, leading to the formation of clouds and precipitation. Recent studies have shown that the reported PBAP concentrations in the atmosphere are highly underestimated. Conducting detailed measurements of PBAP emissions and investigating the particles’ impact on the atmospheric microphysical processes and the climate is the main objective of the EU-funded BIOAAT project. More specifically, the project plans to deliver more realistic predictions of the emission flux and dispersion of PBAP and assess the impact of different types of PBAP on ice cloud and precipitation formation.
Objective
Primary biological aerosols particles (PBAP) are emitted from the land and marine surfaces into the atmosphere, where they were found to be abundant. The PBAP are of high importance because of their potential involvement on ice-nucleation (IN) and precipitation formation processes, with potential implications on the climate. Older studies showed that the total concentration of PBAP is smaller than other types of ice-nucleation particles, e.g. dust, while recent studies showed that the reported concentrations of PBAP are highly underestimated, thus, their IN activity and climatic impacts have large uncertainty. According to the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), the PBAP-cloud interactions, as a part of aerosol-cloud interactions, are still the least understood factor in our current understanding of climate change. In addition, combating climate change and its impacts is one of the Sustainable Development Goals of the United Nations. Therefore, it’s crucial to carry out further investigations on the emissions of PBAP and their consequent atmospheric microphysical processes and climatic impacts and feedbacks, which is the main objective of BIOAAT. The BIOAAT aims to: (i) deliver more realistic prediction of the emission flux and dispersion of PBAP; considering all ecosystems and meteorological conditions that lead to high variation in quantifying their concentrations, distributions, and emission fluxes, (ii) close the gap between observations and modelling studies on the impact of different types of PBAP on cloud ice and precipitation formation, and contribute to reducing the uncertainty of aerosol-cloud interactions, and (iii) ultimately delivers open-source models that describe the emission flux and ice nucleation rates of PBAP that can easily be implemented in different types of atmospheric models including climate models to better estimate past, present and future climate and environmental impacts of PBAP.
