Article
Accés obertAn international comparison of continuous monitors measuring radon activity concentration was performed to validate the traceability of the European radon calibration facilities. It was carried out by comparing the secondary ... -
Metrology for low-cost CO2 sensors applications: the case of a steady-state through-flow (SS-TF) chamber for CO2 fluxes observations
Curcoll Masanes, Roger; Morguí, Josep-Anton; Kamnang, Armand; Cañas, Lidia; Vargas Drechsler, Arturo; Grossi, Claudia (2022-05-09)
Article
Accés obertSoil CO2 emissions are one of the largest contributions to the global carbon cycle, and a full understanding of processes generating them and how climate change may modify them is needed and still uncertain. Thus, a dense ... -
New metrology for radon at the environmental level
Röttger, Annette; Röttger, Stefan; Grossi, Claudia; Vargas Drechsler, Arturo; Curcoll Masanes, Roger; Otáhal, Petr; Hernández Ceballos, Miguel Ángel; Cinelli, Giorgia; Chambers, Scott Dudley; Barbosa, Susana Alexandra; Ioan, M. R.; Radulescu, Ileana (2021-09-23)
Article
Accés obertRadon gas is the largest source of public exposure to naturally occurring radioactivity. However, radon is also a useful tracer for understanding atmospheric processes, assessing the accuracy of chemical transport models, ... -
Quality study of electret radon flux monitors by an “in situ” intercomparison campaign in Spain
Grossi, Claudia; Vargas Drechsler, Arturo; Arnold, Delia (International Energy Agency, 2011)
Text en actes de congrés
Accés obertRadon is nowadays used as a tracer for atmospheric transport model validation because of its physical and chemical characteristics. 222Rn source term characterization becomes necessary for more accurate validations into ... -
Radon
Grossi, Claudia (2019-05-01)
Capítol de llibre
Accés obertRadon isotopes (222Rn, 220Rn) are noble, naturally occurring radioactive gases. They originate from the alpha decay of radium isotopes (226Ra, 224Ra), which occur in most materials in the environment, i.e. soil, rocks, raw ... -
Radon metrology for use in climate change observation and radiation protection at the environmental level
Röttger, Stefan; Röttger, Annette; Grossi, Claudia; Vargas Drechsler, Arturo; Karstens, Ute; Cinelli, Giorgia; Chung, Edward; Kikaj, Dafina; Rennick, Chris; Mertes, Florian; Radulescu, Ileana (European Geosciences Union (EGU), 2022-03-10)
Article
Accés obertRadon (222Rn) gas is the largest source of public exposure to naturally occurring radioactivity and the identification of radon priority areas is required by the Council Directive 2013/59/Euratom. Radon is also used as a ... -
Study of the daily and seasonal atmospheric CH4 mixing ratio variability in a rural Spanish region using Rn-222 tracer
Grossi, Claudia; Vogel, F. R.; Curcoll, Roger; Agueda Costafreda, Alba; Vargas Drechsler, Arturo; Rodó, Xavier; Morguí, Josep Anton (2018-04-26)
Article
Accés obertThe ClimaDat station at Gredos (GIC3) has been continuously measuring atmospheric (dry air) mixing ratios of carbon dioxide (CO2) and methane (CH4), as well as meteorological parameters, since November 2012. In this study ... -
Temporal and spatial variability of ground level atmospheric methane concentrations in the Ebro River Delta
Agueda Costafreda, Alba; Grossi, Claudia; Pastor Ferrer, Elsa; Rioja, Eva (2017-07)
Article
Accés restringit per política de l'editorialDeltas provide many worthy ecosystem services. Yet, delta basins are quite vulnerable, especially in the face of climate change, which can affect the outcome of both agriculture and biodiversity. Moreover, rice paddy ... -
