Morphology

reanalysis = analysis (semi-transparent) = re + analysis

Although morphologically 're-' + 'analysis', this sense is a technical term in climate science referring to a specific processed dataset, which is not fully predictable for general learners.

Etymology

Reanalysis comes from re- 'again' and analysis 'careful study'. In weather science, a reanalysis is what you get when scientists apply the same method to old weather records to make a single, consistent dataset for comparing the past.
