[1] Formaldehyde (HCHO) columns measured from
space by solar UV backscatter allow mapping of reactive
hydrocarbon emissions. The principal contributor to these
emissions during the growing season is the biogenic hydro-
carbon isoprene, which is of great importance for driving
regional and global tropospheric chemistry. We present
seven years (19952001) of HCHO column data for North
America from the Global Ozone Monitoring Experiment
(GOME), and show that the general seasonal and interannual
variability of these data is consistent with knowledge of
