These 10 images were chosen because they have no interfering cloud cover, are all large expanses of ice uninterupted by the ocean, and together they represent a range of melt pond stages--thus providing multiple area fraction values. I had many other small images (less than 1500 in either width or height) which weren't necessary because they would have added very little data--because the large images are split up into many smaller images in the program.

The images are all scaled equally; each pixel represents a meter by meter square area. A 200 by 200 pixel image represents a 200 by 200 meter square area in the arctic

Explanation of labelling: I labelled each image by the array number first, followed by the buoy number, the date it was taken, and then an index (m,ma,mb,or mc) which distinguish images when multiple were taken on the same day from the same buoy location--m means it was the only image, and ma-mc help identify image when multiple were taken. Any following numeral subindex is to identify multiple images cropped from the same larger image.

Images were downloaded as tiff files from the Global Fiducials Library access portal and then cropped with gimp. Link here: https://gfl.usgs.gov/gallery_main.shtml?current=4

Specifically the images were taken as part of the ONR Marginal Ice Zone Program. Info can be found here: http://www.apl.washington.edu/project/project.php?id=miz
