Cloud water collections have been made on Mt. Mitchell using a nearly real-time cloud and rain acidity/conductivity (CRAC) analyzer. Results are reported for integrating times of approximately 5 min during several cloud events in the summer and fall

A field study was conducted to compare methods for sampling and analysis of atmospheric constituents that are important contributors to acidic dry deposition. Comparisons are made of different measurements of ambient concentrations of gaseous HNO 3 ,

An acid precipitation monitor has been developed that collects fractions of rain events, measures the pH and conductivity in real-time, and stores the remaining samples under refrigerated conditions. A Z-80 microprocessor controls all operations of t

The flash photolysis of HN3 was studied by coordinated time-resolved spectroscopic measurements of HN3 NH(a1Δ), NH(X3Σ), NH(c1π), NH(A3π), NH2, and N3 following flash photolysis of mixtures of HN3 with argon or helium. The primary photolysis is c

Fine and coarse mode aerosol particles were collected for 16 months at three rural sites spanning a 600 km length of the Ohio River Valley. Particle mass and concentrations of 15 elements are reported as means, quarterly means and parameters of the f

We describe a method for the comparison of measurements of the same pollutant taken simultaneously by two instruments. The method requires no information about the precision of the instruments and does not assume, as the typically used linear regress

A gas chromatographic technique that measures atmospheric concentrations of peroxyacetyl nitrate (PAN) and NO/sub 2/ has been developed that uses luminol-based chemiluminescence for detection. The carrier gas is air that has been scrubbed by passing

During the period May 1980–August 1981, air quality measurements were made at three rural sites in the Ohio River Valley. Monthly averages of O 3 , NO 2 and gaseous and particulate sulfur were quite uniform from site to site and showed a strong ann

This research is a preliminary survey to explore a possible analogy between the chemistry of the NH singlet radical and its electronic isomer, O( 1 D). The flash decomposition of HN 3 forms NH(a 1 Δ) as the predominant observable primary product. Th

The ozone ultraviolet spectrum has been re‐examined at low temperature to clarify features of photochemical interest. The origin of the system is a diffuse band at 28 450 cm−1, the long wavelength limit of band structure in the cold spectrum. The
