I have MCD43A3 product and I am using that to get the albedo values(Black sky and White Sky). I have some in-situ snow depth data, corresponding to which I want to get these albedo values.
For most of the in-situ data I'm getting a value of 32767, which is a fill value for the product. For some data I'm getting, a value like 908,889,976 which is multiplied by scale factor of 0.0010 to get the albedo values like .908,.889,.976.
My question is what should I do about the 32767 values which I am getting for most part of my data? Does getting this type of value mean that the image has noise or error? I have little experience with MCD products, any kind of help would be appreciated. Thanks, GBh
