COSMOS-Europe: a European network of cosmic-ray neutron soil moisture sensors

[EN] Climate change increases the occurrence and severity of droughts due to increasing temperatures, altered circulation patterns, and reduced snow occurrence. While Europe has suffered from drought events in the last decade unlike ever seen since the beginning of weather recordings, harmonized long-term datasets across the continent are needed to monitor change and support predictions. Here we present soil moisture data from 66 cosmic-ray neutron sensors (CRNSs) in Europe (COSMOS-Europe for short) covering recent drought events. The CRNS sites are distributed across Europe and cover all major land use types and climate zones in Europe. The raw neutron count data from the CRNS stations were provided by 24 research institutions and processed using state-of-the-art methods. The harmonized processing included correction of the raw neutron counts and a harmonized methodology for the conversion into soil moisture based on available in situ information. In addition, the uncertainty estimate is provided with the dataset, information that is particularly useful for remote sensing and modeling applications. This paper presents the current spatiotemporal coverage of CRNS stations in Europe and describes the protocols for data processing from raw measurements to consistent soil moisture products. The data of the presented COSMOS-Europe network open up a manifold of potential applications for environmental research, such as remote sensing data validation, trend analysis, or model assimilation The dataset could be of particular importance for the analysis of extreme climatic events at the continental scale. Due its timely relevance in the scope of climate change in the recent years, we demonstrate this potential application with a brief analysis on the spatiotemporal soil moisture variability.

Análisis probabilístico de estándares de emisión para el dimensionamiento volumétrico de tanques de tormenta

[ES] El impacto ambiental sobre los medios receptores que provocan los vertidos de escorrent as urbanas desde un tanque de tormentas para el control de la contaminaci on puede enfocarse de dos formas diferentes: estableciendo los denominados est andares de emisi on (Emission Standards, ES) o bien los objetivos de calidad ambiental (Environmental Quality Standards, EQS). El primer nivel en cuanto a objetivos de protecci on lo constituyen los est andares de emisi on. Con ellos se estudian e imponen restricciones a los vertidos, evaluando su frecuencia, volumen, carga contaminante, etc. Las m as habituales hacen referencia a la frecuencia de los vertidos y a la reducci on del volumen de escorrent a vertido al medio receptor. El art culo presenta el desarrollo de un modelo anal tico probabil stico para el an alisis de est andares de emisi on en un tanque de tormentas para el control de la contaminaci on procedente de escorrent as urbanas. Los resultados obtenidos se aplican y se contrastan mediante simulaci on matem atica en una cuenca de la ciudad de Valencia. Finalmente, se sintetizan en abacos que proporcionan el valor del est andar de emisi on alcanzado en funci on de los dos par ametros b asicos de dise~no del tanque: su volumen y el caudal derivado a depuraci on.Andrés Doménech, I.; Marco Segura, JB.; Vallés Morán, FJ.; Albentosa Hernández, E.
