Bioaerosols have risen as pivotal constituents of airborne particles. Closely intertwined with the agricultural domain, these particles exert a significant influence on crops through dissemination various microorganisms that modulate crop growth dynamics, adaptive responses to environmental stimuli, and nutritional profile products. As main vector, are at forefront in transmission plant pathogens. Therefore, this review explains factors influencing their composition settings spreading. Furthermore, it elucidates complex bioaerosol-based communication networks, including bacteria–bacteria, bacteria–plant, plant–plant interactions, mediated by specialized volatile organic compounds (VOCs) released plants bacterial (BVCs) produced bacteria. These play crucial role synchronizing stress facilitating processes. They serve pathway for regulating behavior both microorganisms. Delving into origin dispersion, we assess key methods collection analysis while also comparing strengths weaknesses sampling techniques. The discussion extends delineating roles such formation biodiversity. Central discourse is an in-depth exploration context, particularly focusing potential utility forecasting pathogen subsequent diseases. This highlights importance applying strategies promotion sustainable practices, thus contributing advancement ecological balance food security, which remains neglected area scientific research.

Abstract. The studies of intracloud discharges may shed light on the microphysical structure thunderclouds, as both magnitude and sign charge separation due to graupel collides with ice crystals within strong updrafts are influenced by surrounding environment. Here, a compact all-fiber coherent Doppler wind lidar (CDWL) working at 1.5 µm wavelength is applied for probing dynamics microphysics thunderstorms. Thanks precise spectrum measurement, multi-component spectra signals thunderstorms can be analyzed CDWL. width, skewness, velocity CDWL used separate identify particle composition polarity. In experiment, thundercloud properties detected CDWL, 10.6 cm weather radar (DWR), Advanced Geosynchronous Radiation Imager (AGRI) onboard Fengyun-4 satellites. particular, width skewness below 0 ∘C isotherm increased, when cloud-ground lightning occurs, there additional greater than 5 m s−1.

Abstract. Aerosol–cloud interactions in mixed-phase clouds (MPCs) are one of the most uncertain drivers hydrological cycle and climate change. A synergy situ, remote-sensing modelling experiments were used to determine source ice-nucleating particles (INPs) for MPCs at Mount Helmos eastern Mediterranean. The influences boundary layer turbulence, vertical aerosol distributions meteorological conditions also examined. When observation site is free troposphere (FT), approximately 1 ×106 serve as INPs around −25 °C. INP abundance spans 3 orders magnitude increases following order: marine aerosols; continental and, finally, dust plumes. Biological important observed aerosols, whereas they play a secondary, although important, role during Saharan events. Air masses planetary (PBL) show both enriched concentrations higher proportion total particles, compared with cases FT. presence precipitation/clouds enriches FT but decreases PBL. Additionally, new parameterizations developed that incorporate ratio fluorescent-to-nonfluorescent or coarse-to-fine predict >90 % within an uncertainty range factor 10; these exhibit better performance than current widely allow ice formation models respond variations biological particles. improved can help MPC simulations regions various sources different prevailing sources.

This study aims to investigate the seasonal variation and source identification of fluorescent aerosol particles at monitoring site University Salento in Lecce, southeastern Italy. Utilizing a wideband integrated bioaerosol sensor (WIBS), this research work analyzes data from two specific days: one winter (10 January 2024), marked by significant transport anthropogenic Eastern Europe, another early spring (6 March characterized marine sources occasional desert dust. focuses on seven WIBS particle categories (A, B, C, AB, AC, BC, ABC), which exhibited distinct characteristics between days, indicating different compositions. Winter measurements revealed predominance fine-mode particles, particularly soot bacteria. In contrast, showed larger including fungal spores, pollen fragments, mineral Fluorescence intensity further emphasized an increase biological organic airborne material spring.
