Formaldehyde, H 2 CO, has been detected in the atmosphere at 2807 and 2869 cm −1 using high resolution infrared absorption spectroscopy from a ground based station. An order of magnitude measure of the column concentration (5 × 10 15 molecules per cm²) is given, and an estimate of the trospospheric and stratospheric concentrations is derived from the line pressure broadening.
