Even though some HCHO and HCDO is lost to reactions through the course of the experiment the model shows that this a ff ects both formalde- hyde isotopologues almost equally (i.e.

On the other hand, at- mospheric photooxidation of these fluorinated alcohols, ini- tiated by hydroxyl (OH) radicals and chlorine (Cl) atoms, is known to yield fluorinated aldehydes

In addition to continuous measurement of the laser power throughout the field exper- iments, the instrument’s Raman scattering sensitivity was measured nightly by over- flowing

Instrument problems during the 2007 study meant that only HO 2 was measured for the early part of the campaign, with simultaneous observations of OH and HO 2 possible during the last

All other long- lived forcing terms reflect the steady state response of the atmosphere to sustained aircraft NO x emissions of the year 2000, based on methane lifetime changes due

The kinetic isotope e ff ects in the reactions of CH 3 Cl, 13 CH 3 Cl and CD 3 Cl with OH radicals and Cl atoms were studied in relative rate experiments at 298 ± 2 K and 1013 ±

Another impact of non-acyl peroxy nitrates is that they are a possible positive inter- ference to in-situ NO 2 measurements in the upper troposphere because the non-acyl peroxy
