Science Goals for MANTRA 2004

  1. To fly a comprehensive suite of instruments in order to measure the vertical profiles of the key stratospheric species that control the mid-latitude ozone budget, particularly species in the NOy, Cly, Bry, and HOx chemical families, along with dynamical tracers and aerosols.

  2. To combine these measurements with those obtained from similar northern mid-latitude campaigns of the past 20 years, in order to quantify changes in the chemical balance of the stratosphere.

  3. To compare multiple measurements of the same trace species made by different instruments, in order to resolve previously observed discrepancies and to assess the instruments performance.

  4. To use the 2004 measurements for validation and ground-truthing of the SCISAT-1 mission.
