| Zusammenfassung |
| Although the concentration of CH4 in the atmosphere is well known and many
studies show that the concentration of this gas has more than doubled since the
industrial revolution, the emission sources are poorly identified and usually have large
uncertainties. However, due to the importance of this green house gas in climate forcing,
more studies on its concentration and distribution need to be made globally through
satellite measurements and international networks, but also on the regional and local
scales.
In this work we present the first results of CH4 vertical columms measured from a station
located in the university campus of UNAM in Mexico City. We describe the methodology
based on solar absorption FTIR spectroscopy and present preliminary results from 2007 until
present. |
