... measurement sites that allow for a meaningful examination of long range transport and trends in background concentrations. The global air quality issues discussed in this report intersect with the concerns of several federal agencies, yet none of these agencies have a clear mandate to lead U.S.

... These two recommendations will require providing support to: develop uniform and traceable standards on a global basis for calibration of both gas-phase and aerosol measurements; improve measurement technologies for use in current observational platforms (such as ground-based air quality monitoring networks, commercial aircraft, and balloons/sondes) , and in new potential platforms such as "supersites" for measuring a comprehensive suite of compounds in remote locations, and unmanned aerial vehicles for longduration sampling of the atmosphere over a wide range of altitudes; integrate measurements obtained from different observational programs and platforms with a particular focus on integrating remotely sensed satellite observations with in situ aircraft and ground-based measurements; · promote observational programs specifically designed to address chemical and meteorological data requirements for the improvement and validation of models.

... Similarly, the International Global Atmospheric Chemistry project (of the International Geosphere-Biosphere Programme) has strongly endorsed the need for international exchange of calibration standards and has helped coordinate multinational field campaigns to address a variety of important issues related to global air quality.
