This report aims to describe the technical characteristics and operating methods of the sampling system for the atmospheric measurement of radiocarbon (14CO2) developed by the University of Heidelberg (Germany) as part of the pan-European research infrastructure ICOS-RI (Integrated Carbon Observation System - Research Infrastructure, https://www.icos-cp.eu/). This infrastructure works to provide harmonized and high-precision scientific data relating to the carbon cycle (flows between vegetation, atmosphere and oceans) and concentrations of greenhouse gases such as carbon dioxide or carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), sulfur hexafluoride (SF6), etc., mainly used for studies on climate change in order to understand its evolution and to predict and mitigate its impacts. And it is within this research infrastructure that the Institute of Methodologies for Environmental Analysis (IMAA) of the National Research Council (CNR), with its own station in Potenza, will operate as a continental type site (i.e., sites affected by continental type air masses) of class 1 (i.e. maximum number of measured parameters expected, between mandatory and recommended) of the ICOS-atmosphere component, i.e. the component that collects data on greenhouse gas concentrations in atmosphere. The parameters whose measurement is considered mandatory at ICOS class 1 sites includes 14CO2 whose sampling system and operating mode, as already mentioned, are the subject of this technical report. In particular, this document, in addition to briefly explaining the sampling methodology, provides the description of the system used to measure this parameter in terms of parts and their positioning / assembly, as well as the operational indications necessary for the replacement of the samples. It is emphasized that the information contained in this report, as well as all the images included in it, were taken from the document available on the ICOS portal and downloadable at the following link: https://www.icos-cal.eu/static/misc /crl/Description_Heidelberg_14CO2_Sampler.pdf.
Questo report ha l'obiettivo di descrivere le caratteristiche tecniche e le modalità operative del sistema di campionamento per la misura in atmosfera del radiocarbonio (14CO2) sviluppato dall'Università di Heidelberg (Germania) nell'ambito dell'infrastruttura di ricerca paneuropea ICOS-RI (Integrated Carbon Observation System - Research Infrastructure, https://www.icos-cp.eu/). Tale infrastruttura opera per fornire dati scientifici armonizzati e di alta precisione relativi al ciclo del carbonio (flussi tra vegetazione, atmosfera e oceani) ed alle concentrazioni di gas a effetto serra quali biossido di carbonio o anidride carbonica (CO2), metano (CH4), protossido di azoto (N2O), esafluoruro di zolfo (SF6), ecc., utilizzati principalmente per studi sui cambiamenti climatici al fine di comprenderne l'evoluzione e per predirne e mitigarne gli impatti. Ed è proprio all'interno di questa infrastruttura di ricerca che l'Istituto di Metodologie per l'Analisi Ambientale (IMAA) del Consiglio Nazionale delle Ricerche (CNR), con la propria stazione di Potenza, opererà in qualità di sito di tipo continentale (i.e. siti interessati da masse d'aria di tipo continentale) di classe 1 (i.e. numero massimo di parametri misurati previsto, tra obbligatori e raccomandati) della componente ICOS-atmosfera, ovvero la componente che si occupa di raccogliere dati sulle concentrazioni di gas serra in atmosfera. Tra i parametri la cui misura è considerata obbligatoria presso i siti ICOS di classe 1 rientra il 14CO2 il cui sistema di campionamento e la cui modalità operativa, come già anticipato, sono oggetto del presente report tecnico. In particolare, questo documento, oltre a esporre brevemente la metodologia di campionamento, fornisce la descrizione del sistema utilizzato per la misura di tale parametro in termini di parti e di posizionamento/montaggio delle stesse nonché le indicazioni operative necessarie per la sostituzione dei campioni. Si sottolinea come le informazioni riportate nel presente report, così come tutte le immagini in esso inserite, sono state desunte dal documento disponibile sul portale di ICOS e scaricabile al link seguente: https://www.icos-cal.eu/static/misc/crl/Description_Heidelberg_14CO2_Sampler.pdf.
