These measurements are performed by ICTA-UAB in the framework of the ERC URBAG project (https://urbag.eu/) and are a contribution to the ICOS Cities (a.k.a PAUL) project (GA 101037319). Measurements are performed with Picarro CRDS instruments. Water vapor correction according to Rella et al., 2023. Daily target tank for drift detection. 4 point working standard calibration every 2-3 weeks. Working standards are calibrated using 6 NOAA secondary standards.
