| Summary: | During the European project COST ES0601 (HOME) a new
homogenisation method, ACMANT has been developed for the automatic
homogenisation of monthly temperatures. ACMANT turned out to be one of the
best performing methods during the blind test experiments of HOME. The
methodological development of ACMANT has been continued since then, and
nowadays ACMANT is likely the best homogenisation method for large and
spatially dense temperature datasets. Ensemble moving parameter experiments
have been done to obtain more information about the performance of ACMANT.
The HOME Benchmark was used as test dataset, thus the results of the latest
experiments with ACMANT are comparable with the performance of the other
homogenisation methods participated in HOME. The results indicate that the
performance of ACMANT is generally not sensitive to its parameterisation,
i.e. the change of the performance is generally small for quite a wide range
of each parameter. The presented methodology of moving parameter experiments
provides results in a fast and easy to evaluate form. |
