Short summary
HAI is a fully autonomous, airborne hygrometer for atmospheric investigations for simultaneous gas-phase/total H2O detection on the HALO aircraft. HAI employs first-principle, direct, tunable diode laser absorption spectroscopy (dTDLAS) for calibration-free, absolute H2O detection. HAI simultaneously measures at 1.4/2.6 µm and in closed-/open-path configuration, covers a H2O range of 1–40 000ppmv at up to 1.4 ms time resolution and achieves precisions of 0.18/0.055 ppmv at 1.4/2.6 µm.
