The Atmospheric Science Data Center (ASDC) has released the data for the Stratospheric Tracers of Atmospheric Transport (STRAT) campaign. STRAT was conducted by NASA from May 1995 to February 1996, with the primary goal of collecting measurements of the change of long-lived tracers and functions of altitude, latitude, and season. To accomplish its objectives, the STRAT team conducted various surface-based remote sending and in-situ measurements. The ER-2 aircraft was deployed along with ozonesondes and radiosondes just below the tropopause in the Northern Hemisphere. Nine collections are publicly available via Earthdata Search and the ASDC’s Direct Data Download.
