Abstract: 1 table. 3 figures. [CO2 uptake and water content were studied at sites in California. "At the inland site, CO2 fixation was concentrated in the rainy winter season and very little CO2 fixation took place during the hot summers. In contrast, fog and high atmospheric humidity that frequently occur during summers at the coast provided sufficient moisture for frequent photosynthetic activity, thus resulting in intermittent activity throughout the year."]
