Evaluation of new laser spectrometer techniques for in-situ carbon monoxide measurements
Long-term time series of the atmospheric composition are essential for environmental research and thus require compatible, multi-decadal monitoring activities. The current data quality objectives of the World Meteorological Organization (WMO) for carbon monoxide (CO) in the atmosphere are very challenging to meet with the measurement techniques that have been used until recently. During the pas...
متن کاملAbsorption measurements of carbon monoxide laser radiation by water vapor.
An intracavity water vapor cell in conjunction with a CO laser was used to measure experimentally the absorptive losses introduced for nineteen of the laser emission lines. The results indicated that the existing theoretical models are inadequate for predicting actual absorptance values for water vapor partial pressures in excess of 100 Torr. The accepted spectral location of at least one water...
متن کاملEnd-tidal Carbon Dioxide Measurements in Unintentional Non-Fire-Related Carbon Monoxide Poisoning
Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...

متن کاملA broadband cavity ringdown spectrometer for in-situ measurements
This paper describes a broadband cavity ringdown spectrometer and its deployment during the 2002 North Atlantic Marine Boundary Layer Experiment (NAMBLEX) to measure ambient concentrations of NO 3 , N 2 O 5 , I 2 and OIO at the Mace Head Atmospheric Research Station, Co. Galway, Ireland. The effective absorption path lengths 5 accessible with the spectrometer generally exceeded 10 km, enabling ...
