Please excuse my ignorance and I’m sure you have stated this before. What does MASSIE tell us? “Biggest Central Arctic Drop” means what? I want to read this correctly but I’m a knuckle dragger.
“MASIE-NH stands for the Multisensor Analyzed Sea Ice Extent – Northern Hemisphere. It is similar to the Sea Ice Index (SII) product in that it is easy to use and gives a graphical view of ice extent in various formats. However, it relies more on visible imagery than on passive microwave data, so the ice edge position will generally be more accurate than that of the Sea Ice Index. ”
