MOAS: an absorption laser spectrometer for sensitive and local monitoring of tropospheric OH and other trace gases

Hydroxyl radical (OH) multipass absorption spectroscopy (MOAS) is a laser optical method for the absolute and in situ monitoring of tropospheric OH with high spatial and temporal resolution. This technique is based on direct absorption measurements and it is made local by folding the absorption path...

Beschreibung
Zusammenfassung:Hydroxyl radical (OH) multipass absorption spectroscopy (MOAS) is a laser optical method for the absolute and in situ monitoring of tropospheric OH with high spatial and temporal resolution. This technique is based on direct absorption measurements and it is made local by folding the absorption path inside a multiple reflection cell with an open path setup.
