FIREX-AQ

mini-DOAS (mini-DOAS)

Status

Operated By:

Max Spoalor and the mini-DOAS instrument.

mini-DOAS uses the Differential Optical Absorption Spectroscopy (DOAS) technique to identify and quantify trace gases using their narrow band absorptions.

This instrument studies:

1) the transport of short-lived halogenated species and their decay products to the stratosphere and the subsequent influence to the photochemistry and budget of Bromine (BrO) in the TTL.
2) the potential impact of halogen oxides to directly destroy UT/LS ozone.

Instrument Type:

Spectrometer

Measurements:

BrO, NO2, O4

Aircraft:

Global Hawk - AFRC

Point(s) of Contact:

Jochen Peter Stutz (POC; PI), Klaus Pfeilsticker (Prev PI)
