Project: CITE-2

The Atmospheric Science Data Center (ASDC) has released data for the Chemical Instrumentation Test and Evaluation (CITE) missions. While there were three deployments for CITE (CITE-1, CITE-2, CITE-3), data is only available for CITE-2 and CITE-3, as CITE-1 data was unable to be located and therefore was not transferred to the ASDC. CITE-2 was conducted in August 1986 over California and the eastern Pacific Ocean with a focus on daytime odd nitrogen and the evaluation of instrumentation developed for measuring nitrogen species. CITE-3 occurred in the North and tropical Atlantic Ocean from August – September 1989 with the goal of testing and evaluating the capacity to collect reliable measurements of sulfur species.
