✦ Synopsis

An open path infrared absorption based instrument for fast response measurements of Hz0 and COa fluctuations is described. This instrument performed reliably in several field experiments in both terrestrial and marine environments, on both fixed (tower) and mobile (boat, plane) flux platforms. Noise levels for Ha0 and COa concentrations were less than 10 mg/m3 and 300 pg/m3, respectively for frequencies between 0.005 and 10 Hz. Drifts in instrument output, associated with changes in instrument temperature, are compensated for electronically.
