Abstract:
Precipitation is a component of the global carbon cycle through which organic carbon enters terrestrial and aquatic ecosystems from the atmosphere. We measured photochemical characteristics of dissolved organic matter in precipitation from Dec. 30, 2015 to Feb. 21, 2017 in Seoul, South Korea.
