uncertainty estimate on seasons

Target

Calculate the uncertainty estmation on different seasons to have an estimate about the seasonal performance of models. E.g. use only the blocks within JJA or "ozone season" (what is the official range? April/May/June to September?)

Tasks

• can use a temporal constraint like "JJA" to extract only blocks within this periods
• apply uncertainty estimate on this subset
• create all plots for this estmiate
• main workflow with all-year uncertainty estimation is not affected.
