Exhaust identification product for MARCUS project aboard Aurora Australis 2017/18

Exhaust identification product calculated using CN and CO data from the ARM AOS facility aboard the Aurora Australis during the 2017/18 resupply season (Austral summer) as part of the Measurements of Aerosols, Radiation and CloUds over the Southern Ocean (MARCUS) project. The product is a binary timeseries (UTC) indicating the presence (True) or absence (False) of exhaust on the atmospheric measurements. The algorithm is described in doi.org/10.5194/amt-12-3019-2019 and is modified for this dataset.

Included here are a number of permutations which vary the number of median absolute deviations (MAD) and percentage threshold for the window filter (see section 3.3 of paper). It is left to the end-user to assess the suitability to their dataset and choose the appropriate permutation for their needs or expand the window filtering to make it more stringent. The authors recommend the exhaust_4mad02thresh as the best output.
