Removal of systematic biases in S-mode principal components arising from unequal grid spacing

Frequently, physical variables are analyzed using gridded fields, on regular latitude-longitude frameworks. Such networks often concentrate a disproportionate number of observations over polar regions. If these types of grids are used for an S-mode principal component analysis, they produce a bias o...
