Biogenic isoprene plays an important role in tropospheric chemistry. Current isoprene emission estimates are highly uncertain due to a lack of direct observations. Formaldehyde (HCHO) is a high-yield product of isoprene oxidation. The short photochemical lifetime of HCHO allows the observations of this trace gas to help constrain isoprene emissions. We use HCHO column observations by the Global Ozone Monitoring Experiment (GOME). These global data are particularly useful for studying large… CONTINUE READING
