Figure S1, details of the Y-type fiber bundle; Figure S2, transmissions of three optical filters; Figure S3, HCHO concentrations retrieved from two fit ranges; Figure S4, convoluted absorption cross sections of typical UV gas absorbers; Figure S5, continuous measurement results of reference spectra with 30 s time resolution; Figure S6, regression plot of binned HCHO IBBCEAS measurements against the Hantzsch measurements (PDF).

The absorption spectrum of formaldehyde at 1.573μm has been recorded at room temperature with a typical sensitivity of 6×10-8cm-1 by using an off-axis integrated cavity output spectroscopy set-up based on a distributed feedback diode laser. Daniel Mariuta, Arumugam Govindaraji, Stéphane Colin, Christine Barrot, Stéphane Le Calvé, Jan G. Korvink, Lucien Baldas, Jürgen J. Brandner. The combined light source based on a Y-type fiber bundle overcomes the difficulty of measuring ambient HCHO via IBBCEAS in near-ultraviolet range, which may extend IBBCEAS technology to measure other atmospheric trace gases with high precision.
