Documentation for the Active Microwave (scatterometer) derived melt data
This data set consists of 3 columns. The first column gives the year, the second column gives the total number of pixels that experienced melt and the third column is the total surface melt area.
The total surface melt area was obtained by multiplying the total pixel number by the spatial resolution of the scaterometer pixel which is 4.45 sq.km.
It should be noted that, unlike the passive microwave analysis, the scatterometer derived melt area was not calculated on a sector by sector basis. Hence we have only the ice sheet wide total annual melt area estimates from active microwave.
