Abstract:

Precipitation is a component of the global carbon cycle through which organic carbon enters terrestrial and aquatic ecosystems from the atmosphere. We measured Δ14C-DOC (dissolved organic carbon) and Δ14C-POC (particulate organic carbon) in bulk precipitation from Dec. 30, 2015 to Feb. 21, 2017 in Seoul, South Korea.

Keyword(s):
