Estimation of Potential Source Region in Northeast Asia through Continuous In-Situ Measurement of Atmospheric CO2 at Gosan, Jeju Island, Korea

Abstract

High-Precision (¡_0.1 ppm), high-frequency (hourly averaged) measurement of atmospheric carbon dioxide (CO2) was made at Gosan Station on Jeju Island, Korea, using a Non-dispersive Infrared (NDIR) analyzer calibrated with National Oceanic and Atmospheric Administration/Earth Sys tem Re search Laboratory standards. This paper presents the one-year results from these measurements, including discussions on data quality control and data selection, data characteristics through comparing with other regional data and on the techniques for estimating potential source regions of pollution emissions in Northeast Asia with pollution events in the record.
