Measurement of Greenhouse Gases
During the last weeks, unusual high temperatures have been measured inside the arctic circle. Although occurring in a remote region, such temperature increases can have severe consequences with global impact, such as the release of greenhouse gases (GHGs) from the permafrost.
Bruker’s high-end FT-IR spectrometer IFS 125HR and the portable FT-IR spectrometer EM27/SUN can use the sun as the light source in order to measure the total column of GHGs in the atmosphere and to investigate its impact on climate change. With its unique ultrahigh resolution (0.0063 cm-1 or higher), the possible broad spectral range and the possibility to equip it with a solar tracker, the IFS 125HR is the perfect stationary instrument also at exotic locations around the globe. As such it can monitor atmospheric absorbances from a large number of relevant GHGs and it allows to disentangle contributions from different atmospheric layers.
Thanks to its very compact and robust design, several EM27/SUN have been deployed around major cities such as Berlin, Paris, and Tokyo to quantify their emission rate of GHGs like CO2. These successful campaigns demonstrate that EM27/SUN is a valuable tool to obtain important information on regional emissions.
