On the 18th of this month, the Korea Meteorological Administration (KMA) said the annual average greenhouse gas concentration rate of increase has steadily risen over the last decade in the Korean Peninsula to 2.09 ppm/yr (0.5%). Ppm (parts per million) is a unit of measurement used to describe values of miscellaneous dimensionless quantities out of a million, being the total.
In the “2014 analysis of greenhouse gas concentrations in the Korean Peninsula,” report the KMA said that the average annual concentration of carbon dioxide was 404.8 ppm in Anmyeon-do, 404.2 ppm in the Jeju-do high mountain area, 403.1 ppm in Ulleung-do, and 403.3 ppm in Dok-do. The value in Ulleung-do and Dok-do clean areas, which have smaller local pollution sources, was lower than that of Anmyeon-do located at a similar latitude, by about 1.7 ppm.
Over the last ten years (2005 – 2014), the Amnyeon-do average annual CO2 concentration rate of increase was 2.09 ppm/yr, similar to the global average concentration rate of increase (2004 – 2013) which was 2.07 ppm/yr. The average annual CO2 concentration observed in Anmyeon-do last year was up 2.4 ppm, in comparison to Mauna Loa (USA), it was 6.3 ppm higher and the fluctuation range of the average monthly concentration was about 6.7 ppm higher. The Anmyeon-do Observatory is a regional observation station for the Global Atmospheric Watch (GAW), and is registered as a global observation station with the Mauna Loa (USA) Observatory.
The CO2 concentration levels observed in the regional GAW stations is higher than that of global observation stations, which are positioned in areas with clean air and water.
KMA provides the average daily CO2 concentration levels through the Climate Change Information Center website in real-time to raise awareness about the greenhouse gas concentration levels in the Korean Peninsula and to help people develop an understanding of climate change.
The main observations on substances causing climate change in the Korean peninsula will be released on the 30th of next month.
