Abstract. This study aims to investigate global, regional and seasonal temporal dust changes as well the effect of particles on total aerosol loading using ModIs Dust AeroSol (MIDAS) fine-resolution dataset. MIDAS delivers optical depth (DOD) at fine spatial resolution (0.1∘×0.1∘) spanning from 2003 2017. Within this period, burden increased across central Sahara (up 0.023 yr−1) Arabian Peninsula 0.024 yr−1). Both regions observed their highest trends in summer 0.031 On other hand, declining...
Abstract. In August 2021, a historic heatwave was recorded in Greece which resulted extreme wildfire events that strongly affected the air quality over city of Athens. Saharan dust also transferred on certain days same period due to prevailing southern winds. The impact these and surface solar radiation is investigated this study. Event characterization based active passive remote sensing instrumentation has been performed. study shows significantly increased levels pollution were from end...
PM2.5 measurements using a network of lost-cost sensors were conducted during 2017–2019 in the greater area Patras, Greece. The average concentration all sites study period was 9.4 μg m−3, varying from 6.2 m−3 background areas to 12.8 at city center. site with peak levels not located an high traffic density but rather square pedestrian-only zones and restaurant density. highest concentrations observed colder (November–March) due emissions residential wood burning for heating purposes. used...
Solar forecasting constitutes a critical tool for operating, producing and storing generated power from solar farms. In the framework of International Energy Agency’s Photovoltaic Power Systems Program Task 16, irradiance nowcast algorithms, based on five all-sky imagers (ASIs), are used to investigate feasibility ASIs foresee ramp events. 1–2 3–5 can capture true events by 26.0–51.0% 49.0–92.0% cases, respectively. provided lowest (<10.0%) falsely documented while recorded false up...
Particular matter (PM) constitutes one of the major air pollutants. Human exposure to fine PM (PM with a median diameter less than or equal 2.5 μm, PM2.5) has many negative and diverse outcomes for human health, such as respiratory mortality, lung cancer, etc. Accurate air-quality forecasting on regional scale enables local agencies design apply appropriate policies (e.g., meet specific emissions limitations) tackle problem pollution. Under this framework, low-cost sensors have recently...
Over the last decade, low-cost sensors (LCSs) have improved air quality monitoring by enabling widespread, community-driven data collection, particularly in regions with limited resources. Although these LCSs increased public engagement and enriched datasets for understanding pollution dynamics, challenges related to quality, standardization, interoperability hindered their full integration into regulatory frameworks large-scale environmental (Barkjohn et al., 2024; Carotenuto 2023). The...
Indoor air quality (IAQ) plays a vital role in providing healthier indoor environments, especially considering that most human activities occur indoors.&#160; Since and outdoor pollutants are closely interrelated, monitoring both can provide insights into IAQ dynamics.&#160;&#160; The IDEAL (Indoor Air Quality Health) Cluster comprises seven Horizon-Europe funded projects (InChildHealth, INQUIRE, LEARN, K-HealthinAIR, SynAir-G, TWINAIR, EDIAQI) the Working Group (WG) on Sensors...
Low-cost sensors (LCSs) for particulate matter (PM) concentrations have attracted the interest of researchers, supplementing their efforts to quantify PM in higher spatiotemporal resolution. The precision mass concentration measurements from PMS 5003 has been widely documented, though limited information is available regarding size selectivity and number measurement accuracy. In this work, sensors, along with a Federal Referral Methods (FRM) sampler (Grimm spectrometer), were deployed across...

Atmospheric water vapor is an important greenhouse gas, mainly distributed in the lower tropospheric levels where its concentration varies significantly space and time; consequently, so does precipitable water. This work uses information from thermal infrared images to model (PW) under clear skies. PW measured using a portable sun-photometer obtained through high-cost camera. depends on zenith-point temperature (Tb) exhibiting non-linear positive exponential relationship, with systematic...
