PENGARUH TEMPERATURTERHADAP RADIATIVE FORCING OZON (O3) PERMUKAAN DI GLOBAL ATMOSPHERE WEATHER (GAW) STATION BUKIT KOTO TABANG

Abstract

The level radiative forcing of Ozon (O3) from 2009 to 2012 at the Global Atmosphere Weather
Station (GAW) Station Bukit Kototabang (Agam Regency, West Sumatra) has been analyzed using
IPCC (Intergovernmental Panel Climate Change) method. The results showed that the surface O3
linearly proportional with surface O3 radiative forcing which mean if the radiative forcing measured
increase, there will be increase in temperature at Bukit Kototabang. The radiative forcing surface O3
calculated are 0,93 Wm-2 for 2009, 0,90 Wm-2 for 2010, 1,05 Wm-2 for 2011, and 1,03 Wm-2 for 2012.
The temperature difference based on IPCC method are 0,40 K to 0,60 K from 2009 to 2012, while
temperature difference measured by instrumen AWS (Automatic Weather Station) are 0,1 0C to 2,4 0C.
The temperature difference measured by AWS that is influenced by radiative forcing surface O3 was
analyzed using IBM SPSS Statistics software and coefficient 0,031 is obtained which shows a low
correlation about 3,1% at Bukit Kototabang. The results shows that there are some factors that
influece the surface O3 concentration toward earth surface temperature.
