This study analyses the consequences of an extreme dust storm that occurred in March 2022 on Spanish national photovoltaic (PV) energy supply. event, indeed, substantially raised particulate matter concentrations and aerosol optical depths across country, seriously affecting surface radiation posing a substantial threat not only to individual PV systems but also electricity grid. The research, based analysis forecast weather, environmental electrical data, reveals such event halved capacity factor fleet over period longer than two weeks. A peak drop as high 80% was registered, at level, worst day. underperformance affected market share mix, whose monthly average value fell from predicted 10.9% 7.1%. Despite expectations, however, no significant difference soiling found compared typical losses, thanks occurrence heavier-than-usual rainfall events. facilitated recovery capacity, which returned expected performance factors soon sky cleared.

Abstract. Quantifying the dust optical depth (DOD) and its uncertainty across spatiotemporal scales is key to understanding constraining cycle interactions with Earth System. This study quantifies DOD along monthly year-to-year variability between 2003 2017 at global regional levels based on MIDAS (ModIs Dust AeroSol) dataset, which combines Moderate Resolution Imaging Spectroradiometer (MODIS)-Aqua retrievals Modern-Era Retrospective Analysis for Research Applications, version 2 (MERRA-2), reanalysis products. We also describe annual seasonal geographical distributions of main source regions transport pathways. provides columnar mid-visible (550 nm) fine spatial resolution (0.1∘×0.1∘), expanding current observational capabilities monitoring highly variable features burden. obtain a 0.032±0.003 – approximately quarter (23.4 %±2.4 %) aerosol (AOD) about 1 order magnitude more in Northern Hemisphere (0.056±0.004; 31.8 %±2.7 than Southern (0.008±0.001; 8.2 %±1.1 3.5 times over land (0.070±0.005) ocean (0.019±0.002).

Solar radiation estimation in West Africa: impact of dust conditions during the 2021 dry season

Atmospheric chemistry and physics, Год журнала: 2025, Номер 25(2), С. 997 - 1021

Abstract. The anticipated increase in solar energy production West Africa requires high-quality irradiance estimates, which are affected by meteorological conditions and particular the presence of desert dust aerosols. This study examines impact incorporating into surface temperature estimations. research focuses on a case event March 2021, is characteristic dry season Africa. Significant aerosol emissions at Bodélé Depression associated with Harmattan flow that transports plume westwards. Simulations this were conducted using Weather Research Forecasting (WRF) Model alone, as well coupling it CHIMERE chemistry transport model, three different datasets for initial boundary (CAMS, GOCART, MERRA-2). Results show considering reduces estimation errors global horizontal (GHI) about 75 %. caused an average 18 % reduction during event. Additionally, simulations indicated positive bias optical depth (AOD) PM10 concentrations. choice dataset minimally influenced GHI, temperature, AOD whereas concentrations size distribution significantly affected. underscores importance aerosols forecasting better accuracy.

The ongoing energy transition from conventional fuels to renewable sources (RES) has given nations the potential achieve levels of self-sufficiency previously thought unattainable. RES in form utility-scale solar and wind are currently leading alternatives fossil-fuel generation. Precise location siting that factors efficiency limitations related current future climate variables is essential for enabling green envisioned 2050. In this context, understanding mapping intermittency provides insights system operators their seamless integration into grid. Eastern Mediterranean Middle East (EMME) region harness vast amounts RES. scarcity observations weather station networks lack private sector incentives transitioning mean relevant, supporting studies have been limited. This study employs Weather Research Forecasting model with Chemistry estimate technical EMME countries map hourly generation profiles per source country, simulated reference year 2015 considering conditions. findings indicate by 2050, seven within could transform net exporters, while remaining nine might remain reliant on imports or fossil fuels. Egypt emerges as a "powerhouse", potentially enjoying surplus 76 GW hour, whereas United Arab Emirates may face an annual deficit 955 TWh. Further, we derived during different seasons.

Abstract. Atmospheric mineral dust aerosol constitutes a threat to aircraft engines from deterioration of internal components. Here we fulfil an overdue need quantify engine ingestion at airports worldwide. The vertical distribution is key importance since ascent/descent rates and power both vary with altitude affect ingestion. We use representative jet profile information combined vertically seasonally varying concentrations calculate the “dust dose” ingested by over single ascent or descent. Using Copernicus Atmosphere Monitoring Service (CAMS) model reanalysis, climatological seasonal dose 10 for 2003–2019. Dust doses are mostly largest in Northern Hemisphere summer descent, Delhi June–August (JJA; 6.6 g) followed Niamey March–May (MAM; 4.7 Dubai JJA (4.3 g). Holding patterns altitudes coincident peak can lead substantial quantities ingestion, resulting larger than take-off, climb, taxi phases. compare calculated CAMS spaceborne lidar observations two datasets derived Cloud–Aerosol Lidar Orthogonal Polarization (CALIOP). In general, spatial similar between CALIOP, though large variations magnitude found, producing lower factor 1.9 2.8, particularly when concentration very close surface. show that mitigating action reduce damage could be achieved, firstly moving arrivals departures after sunset secondly altering holding pattern away local altitude, reducing up 44 % 41 respectively. suggest likely low bias reanalysis should considered aviation stakeholders estimating dust-induced wear.
