Optimal estimators for ambient air quality levels
(Elsevier, 1992)
Procedures to estimate missing data, determine extrema, and derive uncertainties for data collected in ambient air monitoring networks are presented. The optimal linear estimators used obtain unbiased, minimum variance ...
Determination of aerosol strong acidity losses due to interactions of collected particles: Results from laboratory and field studies
(Elsevier, 1992-04)
Existing methods of measuring atmospheric aerosol strong acidity adequately prevent neutralization of fine-particle acidity by removing course alkaline particles and gaseous ammonia from air samples. However, these techniques ...
