Rapid Ozone Experiment (ROZE)


Operated By: 
ISAF and friends

Rack installation for FIREX AQ. ISAF is the top-left black box. Other instruments in this rack (clockwise from ISAF) include ROZE (ozone, NASA GSFC), CANOE (nitrogen dioxide, NASA GSFC), and NOAA-CSD LIFs for nitrogen oxide and sulfur dioxide.

The NASA Rapid OZone Experiment (ROZE) is an in situ instrument capable of measuring ozone (O3) throughout the troposphere and lower stratosphere on airborne platforms. The instrument uses cavity-enhanced absorption to measure the amount of ozone in a sampled volume flowing through an optical cell. The high-sensitivity of the cavity-enhanced detection scheme and the small sample volume enable high precision measurements in short integration times, making this instrument suitable for measuring O3 fluxes (the exchange between the Earth's surface and atmosphere) with the eddy covariance technique. The instrument is designed for autonomous operation and requires minimal support (and no gases or dry ice) in the field. An inlet mounted in the free stream is needed to sample ambient air.
