Abstract

The aim of this study is to show the methods to measure and estimate a local atmospheric CO₂variations. At first, we use an apparatus which is over 10 times cheeper than other apparatuses used in other reports, and show that the daily variations of CO₂are affected by vegitation. Secondly, the relationship between a satellite-derived vegitation index and the seasonal CO₂variations is investigated.
