Cryosphere Today produce a dataset of sea ice area, which I shorthand as CT Area. Calculating the daily average over a long period gives an average sea ice area for each day (baseline average), subtracting these daily anomalies from the actual sea ice area data for each day of a given gives the daily anomaly. These daily anomalies are the differences from the average seasonal cycle. I use the period 1980 to 1999 as the baseline average period.
In this post I present graphs of the daily anomaly series from 1980 to 2012. This is a place holder for reference from future posts.
