    Now averaging across the entire #Antarctic last month shows a record high for the month of September...

      @ZLabe hi, can you add the 1-sigma or 2-sigma ranges? this would be useful for identifying high-sigma events

      @ZLabe i understand your point, but how do you express variability in a scenario like this, there is some natural variability in meteorological phenomena that should be expressed someway. I read some articles that refer to 3-sigma events, 5-sigma events... i assume that sigma is defined to some time span or something. Maybe the superposition of all curves defines an envolvent that act like a 2-sigma region, just thinking. Big fan of your plots.

      @santiago In a non-stationary climate, I don't find those statistical interpretations very helpful for my temperature graphics.

      @santiago I usually detrend first before applying any standardization methods when evaluating climate data indices.

      @ZLabe Its almost like a density plot, i kind of close my eyes a bit and sep the sigma curves, we are in the 2-sigma departure to say the least 🤣
