AB: MANTRA (Middle Atmosphere Nitrogen TRend Assessment) is a series of high-altitude balloon campaigns conducted in late summer over Saskatchewan Canada (52øN, 107øW) to measure stratospheric trace gases from a float altitude of about 35 km. Flights have occurred in late August or early September of 1998, 2000, 2002, and 2004. By launching in late summer, dynamical variability is minimized and the changing chemical balance of the stratosphere can be studied, with an emphasis on the nitrogen partitioning. This scenario makes the measurements done during the MANTRA campaigns particularly appropriated for validation of satellite measurements. Vertical distributions of O3, NO2, N2O, BrO, HNO3, HCl, CFC-11, CFC-12, and CH4 were measured by the combination of a Fourier transform infra-red spectrometer, infrared emission filter radiometers, and UV-visible grating spectrometers. Other species such as N2O5, NO, ClONO2, may still be retrieved from the existing dataset. In addition, ozone profiles were obtained from a number of ozonesondes launched almost daily during the campaigns. A suite of ground-based instruments were operated providing O3 and NO2 total columns and vertical profiles. Here we present measurements from all the MANTRA campaigns and compare species measured with existing climatology and with the Canadian Middle Atmosphere Model (CMAM), a fully interactive chemistry-climate model. We discuss the use of the MANTRA dataset for satellite validation with a focus on NO2 and O3. Comparisons we are doing with OSIRIS instrument onboard the Odin satellite and the SCIAMACHY and MIPAS instruments onboard the ENVISAT satellite are discussed.
