Laboratoire de physique moléculaire pour l’atmosphère et l’astrophysique (LPMAA)
UMR 7092


The LPMAA is a joint research unit (UMR 7092) belonging to the Université Pierre et Marie Curie and the Centre National de la Recherche Scientifique (INP, INEE). Since january 1st 2009, LPMAA is also a member of the IPSL research federation.

The research activities of our laboratory focus on molecular physics and its applications for the study of the terrestrial atmosphere and on the understanding of molecular processes in astrophysical environments (comets, planets, interstellar medium). Our expertise ranges from experimental and theoretical studies (IR and UV spectrometry, mass spectrometry, cryogenic surfaces, spectral analyses, calculus of relaxation rates, implementation of molecular data bases) to measurement campaigns (ground and balloon based remote sensing of the troposphere and the stratosphere).

News from the Laboratory:

In 2014, LPMAA will merge with LERMA

In january 2014, LPMAA will merge with LERMA to form LERMA2. All the molecular physics activities, from fundamental processes to applications, will belong to the scientific pole 3 of LERMA2: molecules in the Universe.The studies on terrestrial atmosphere carried out in LERMA2 (including original LERMA and LPMAA activities) will be also part of the research federation IPSL.

On the way to TCCON-Paris

In continuous operation since 2007, the Fourier transform spectrometer (FTS) of LPMAA is about to join TCCON (Total Carbon Column Observing Network). TCCON is an international scientific network dedicated to the measurement of atmospheric trace gases by ground based remote sensing. Installed on the campus of Jussieu right at the heart of Paris, the TCCON-Paris site will be one of the very few sites located in a megacity. As a matter fact it will the first such megacity site in Europe. For more information ...

Fête de la Science at the LPMAA

In the framework of the French "Fête de la Science", the LPMAA has organized five workshops for the public, which are representative for the main activities of our laboratory. The guiding idea was to demonstrate how laboratory studies can serve in the applied sciences, such as planetology, astrophysics and environmental research. In particular, the following questions have been raised:

- How can we measure air quality and pollution at Jussieu (QualAir)?
- How can spectroscopy be used to analyze atmospheric composition?
- How can the extreme temperature conditions of the interstellar medium be realized in the laboratory ?

Activities of the LPMAA were linked to the IPSL project on climate and climate change: "Que savons-nous du climat ? Comment le savons-nous ?". Lab doors were open to the public from Wednesday 12 through Saturday 15. More than 70 visitors took the oppurtunity to participate in our activities that around the basic theme "The molecule — a probe to study atmospheres and astrophysics".
