D.1. Inventory of existing homogenisation methods and benchmark dataset preparation.
- Survey groups or individuals using homogenisation techniques. List currently used techniques together with their strengths and weaknesses. This will be achieved through a questionnaire; and personal contact with recognised experts, an evaluation of results will be presented.
- Comprehensively search the literature: climate Journals, grey literature and Proceedings, non-climate sources.
- Classification of the methods according to: statistical nature (parametric, non-parametric, etc…), data requirements (direct, absolute, relative), time scope (annual, monthly, daily).
- Compilation of the Benchmark Dataset: catalogue of expected inhomogeneity situations, list of suitable real datasets, selection of real datasets, creation of simulated time series reproducing expected problems.
