Background trace gas concentrations in the central United States

Abstract: The concentrations of common trace gaseous constituents of the atmosphere have been measured in clean air in rural Illinois and Missouri. Sulfur dioxide (S02), nitrogen dioxide (NO2), ammonia (NH3), and aldehydes (RCHO) were removed from the air by 1 hour of wet scrubbing. Hydrogen sulfide (I-I2S) was collected by passing air through an impregnated filter for I or 2 hours. Background concentrations of SO•, NO2, and RCHO ranged from less than I to 5 ppb. The NI-L concentrations were found to be as high as 10 pp… Show more

“…Similar concentrations of total measurements of SO,., NO,., and O3 will be discussed first. The aliphatic aldehydes were observed by Breeding et al [1973] in ozone concentration of 20-30 ppb and its variation by not the central United States, the nitrogen dioxide concentrations more than 20% found during both days is quite normal for being around 0.5 to I ppb. In Jfilich {he concentrations of formaldehyde were not quite as high and also ozone was lower than reported from Texas and California.…”

“…Total aliphatic aidehyde concentrations in maritime air over Panama of 0.9 and 3.6 ppb were measured by Lodge and Pate [1966] for the dry and wet season, respectively. Background concentrations of total aldehydes in Illinois and Missouri ranged from less than I ppb to 5 ppb [Breeding et al, 1973]. Much higher formaldehyde or aidehyde mixing ratios are reported for polluted atmospheres [Rayner and Jephcott, 1961;•Iltshuller and McPherson, 1963;Lahmann and Jander, 1968;Cleveland et al, 1977;Siddiqi and Worley, 1977;Tuazon et al, 1978Tuazon et al, , 1979.…”

“…Remote measurements of magmatic volatiles have focused a lot on SO 2 because it is arguably the most readily measurable by absorption spectroscopy, due to its low background concentration in the atmosphere (∼ 1 ppbv in clean air; Breeding et al, 1973), and the strong and distinctive structures in its absorption spectrum both at ultraviolet (UV) and thermal infrared (TIR) wavelengths (see the HITRAN database; Rothman et al, 2009). Measurements of volcanic SO 2 fluxes are widely carried out from the surface since the mid-seventies using the Correlation Spectrometer (COSPEC) instrument (Stoiber et al, 1983;Stix et al, 2008).…”

“…The diurnal variation in the computed ammonia concentration is modest, ranging from --•3-7 ppb. (Field measurements typically give nonurban concentrations of 2-5 ppb [Breeding et al, 1973;Shendrikar and Lodge, 1975]. ) Given this reasonable agreement, the relative rates of the ammonia reaction processes can be assessed.…”
