MODICEv02 bug fix, "cleansing" issues strike again. When we made the .tifs, we set scag outputs of -0.01 to 0.00. This looked like a legitimate 0% snow fraction to MODICE, and it was removing too much ice area. The fix was to read the snow_fraction.dat file, and ignore any pixels with -0.01. Looking at the MOD09GA file, it appears that these locations are set to this value for solar geometry (polar night) and some cirrus clouds, but I'm just guessing. In any case, we do not want MODICE to treat these values as 0% snow!
