Short summary
This paper describes the impact of orbital sampling applied to stratospheric temperature and trace gas fields. Model fields are sampled using real sampling patterns from different satellites. We find that coarse nonuniform sampling patterns may introduce non-negligible errors into the inferred magnitude of temperature and trace gas trends and necessitate considerably longer records for their definitive detection.
