As a follow-up to the successful CINDI project, CINDI-2 (Cabauw Intercomparison of Nitrogen Dioxide Measuring Instruments 2) was held at the KNMI Cabauw / CESAR site in September 2016. The goals of this project were two-fold: to prepare for S5P/TROPOMI validation (launched in 2017) and to initialize the suite of instruments that will be used to create the European Fiducial Reference Measurements for Ground-Based DOAS Air-Quality Observations (FRM4DOAS) network of MAX-DOAS instruments.
The CINDI-2 schedule was as follows:
25 Aug: Start of set-up and instrument testing
12 Sep: CINDI-2 campaign opening event
12 Sep: Start of the semi-blind intercomparison (2 weeks)
26 Sep: Optional 1-week extension of the semi-blind intercomparison
3-7 Oct: Cabauw site kept open for additional experiments and campaign break down.
