In conjunction with the Claremont Nitrogen Species Intercomparison Study, tandem filter units (1,2) designed to collect HNO//3/particulate NO** minus //3 and NH//3/particulate NH** plus //4 were operated every other day for 24-hour sampling periods at seven locations throughout the Los Angeles basin. The sampling methods used are related to the intercomparison study via intensive short-term and long-term average measurements made at Claremont. The results from the six Caltech samplers at Claremont show that there is no statistically significant difference ( alpha equals 0. 05) between colocated samplers of the same kind for the collection of HNO//3.
