Relaxed Eddy Accumulation (REA) time series archive, data level 2
14C data based on measurements from a relaxed eddy accumulation (REA) flask sampling system operated at the Hardau II tall tower in Zurich, Switzerland (CH-Har) as part of the ICOS Cities project. This data archive contains a CSV file with all data and metadata recorded for the REA sampling periods (14C_REA_CH-Har.csv), as well as a CSV file containing only CO2 and Delta-14C flask concentrations, derived ffCO2 concentrations, ffCO2 fluxes and quality flags (14C_REA_CH-Har_short.csv). All variables are described in the included XLSX file (14C_REA_variable_description.xlsx). This version, coupled to ICOS Cities deliverable D3.12, contains data that has undergone final quality control of the flask measurements.
