Preferred term
CITE-2
Definition
- The CITE missions focused on testing and evaluating the ability of instrumentation to measure key tropospheric constituents. The methodology has been the intercomparison of airborne measurements obtained for the same species by instruments utilizing fundamentally different detection principles. These missions provide the instrumentation techniques being employed during the ABLE (Atmospheric Boundary Layer Experiments) missions. The CITE-2 project was conducted aboard the NASA Electra aircraft over California and the eastern Pacific Ocean in Summer 1986. It compared instruments that measured components of the nitrogen oxide photochemical cycle, which strongly influences ozone and OH concentrations in the troposphere. CITE-2 obtained new scientific data on nitrogen dioxide (NO2), nitric acid (HNO3), and peroxyacetyl nitrate (PAN) within both clean (Pacific) and polluted (continental) air. Ancillary instruments recorded abundances of other tropospheric chemical species to test models of tropospheric photochemistry. (en)
