  • Sensitivity analysis: Could better methods be used? A commentary to Klonecki and Levy Clegg, and Toumi, Kerminen and Wexler, Kreidenweis and Zhang, Capaldo and Pandis, Vol. 102 of the Journal of Geophysical Research - D, 1997


Some recent articles, all in volume 102 of the Journal of Geophysical Research, Atmosphere, use sensitivity analysis (SA) for mechanism identification and/or model selection. All authors implement SA via either an elementary one factor at a time (OAT) approach or via a derivative-based method. Both approaches have important limitations and these are discussed in this article. Different methods are suggested to make efficient use of the computations involved. These are a rationalized OAT screening test, a regression-based method, and two implementations of global quantitative sensitivity analysis measures. Costs, advantages and limitations of the proposed strategies are discussed.
