3. Extreme Saharan dust events expand northward over the Atlantic and ...
28 okt 2024 · Unprecedented extreme Saharan dust (duxt) events have recently expanded northward from subtropical NW Africa to the Atlantic and Europe.
Abstract. Unprecedented extreme Saharan dust (duxt) events have recently expanded northward from subtropical NW Africa to the Atlantic and Europe, with severe impacts on the Canary Islands, mainland Spain and continental Portugal. These six historic duxt episodes occurred on 3–5 and 22–29 February 2020, 15–21 February 2021, 14–17 January 2022, 29 January–1 February 2022, and 14–20 March 2022. We analyzed data of 341 governmental air quality monitoring stations (AQMSs) in Spain (330) and Portugal (11), where PM10 and PM2.5 are measured with European norm (EN) standards, and found that during duxt events PM10 concentrations are underestimated due to technical limitations of some PM10 monitors meaning that they can not properly measure extremely high concentrations. We assessed the consistency of PM10 and PM2.5 data and reconstructed 1690 PM10 (1 h average) data points of 48 and 7 AQMSs in Spain and Portugal, respectively, by using our novel “duxt-r” method. During duxt events, 1 h average PM10 and PM2.5 concentrations were within the range 1000–6000 µg m−3 and 400–1200 µg m−3, respectively. The intense winds leading to massive dust plumes occurred within meteorological dipoles formed by a blocking anticyclone over western Europe and a cutoff low located to the southwest, near the Canary Islands and Cape Verde, or into the Sahara. These cyclones reached this region via two main paths: by deviating southward from the Atlantic mid-latitude westerly circulation or northward from th...

Abstract. The Copernicus Atmosphere Monitoring Service (CAMS) provides daily analyses and forecasts of the composition of the atmosphere, including the reactive gases such as O3, CO, NO2, HCHO and SO2; aerosol species; and greenhouse gases. The global CAMS analysis system (IFS-COMPO) is based on the ECMWF Integrated Forecasting System (IFS) for numerical weather prediction (NWP) and assimilates a large number of composition satellite products on top of the meteorological observations ingested in IFS. The CAMS system receives regular upgrades, following the upgrades of IFS. The last upgrade, Cy48R1, operational since 27 June 2023, was major with a large number of code changes, both for IFS-COMPO and for NWP. The main IFS-COMPO innovations include the introduction of full stratospheric chemistry; a major update of the emissions; a major update of the aerosol model, including the representation of secondary organic aerosol; several updates of the dust life cycle and optics; updates to the inorganic chemistry in the troposphere; and the assimilation of Visible Infrared Imaging Radiometer Suite (VIIRS) aerosol optical depth (AOD) and TROPOspheric Monitoring Instrument (TROPOMI) CO. The CAMS Cy48R1 upgrade was validated using a large number of independent measurement datasets, including surface in situ, surface remote sensing, routine aircraft, and balloon and satellite observations. In this paper we present the validation results for Cy48R1 by comparing them with the skill of the...

The first European Climate Risk Assessment (EUCRA) identifies 36 climate risks that pose a threat to Europe’s energy and food security, ecosystems, infrastructure, water resources, financial stability, and people’s health. It shows that many of these risks have already reached critical levels and can become catastrophic without urgent and decisive action. The knowledge in this first-of-its-kind assessment is synthesised to support strategic policymaking.

Fog is a critical weather phenomenon for many aspects in society, in particular for the health and transportation sectors. Due to the multiplicity of processes fog forecasting remains a challenge, even with the currently available computer resources. Typically, even mesoscale meteorological models have difficulties with the timing of the onset and dissipation of the fog, as well as its vertical extension. In this study we document the case study of a severe radiation fog (about 200 m deep) as observed at the Cabauw tower (Netherlands) on the night of 6-7 October 2005.We evaluate the single column model version of theWeather Research and Forecasting model (WRF), for a number of permutations of the turbulence scheme, the radiation scheme, and the microphysics scheme. Concerning the fog onset, the YSU turbulence scheme delays the start of the fog substantially compared to the observations and compared to the local MYJ and QNSE schemes. Especially the fog forecast with the double moment microphysics scheme WDM6 outperforms the single moment schemeWSM6 for the fog dissipation. The variation of relevant variables for the fog formation is then explained using so called process diagrams in which the land surface coupling, boundary-layer mixing and longwave radiation intensity are varied. In addition, we evaluate the Dutch Atmospheric Large Eddy Simulation model for this fog episode and critically compare the turbulent intensity relative to the 1D WRF model forecasts.
8. Devastating rainfall hits Spain in yet another flood-related disaster
31 okt 2024 · Record-breaking rainfall and flash floods have hit Spain, causing many dozens of casualties and massive disruption and economic losses.
The Valencia region was worst affected, with many places receiving more than 300 l/m². On 29/30 October, a weather station in Chiva received 491 l/m² in just eight hours - the equivalent of a year's worth of rainfall, according to AEMET - Agencia Estatal de Meteorología.

Technical guidance to prepare national emission inventories. This joint EMEP/EEA air pollutant emission inventory guidebook supports the reporting of air emissions data under the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP) and the EU National Emission reduction Commitment Directive. It provides expert guidance on how to compile an atmospheric emissions inventory. The Guidebook is published by the EEA with the CLRTAP Task Force on Emission Inventories and Projections responsible for the technical content of the chapters. This Technical guidebook is considered valid for the estimation of air emissions going forward in relation to Decision 2022/2 of the Executive Body of the Air Convention.
