Has anyone worked with VIIRS Day Night Band? I want to download few images to get a map of night scene of Central Europe (city lights etc). I use friendly interface at NOAA (http://www.class.ncdc.noaa.gov/saa/products/search?datatype_family=VIIRS) and I've downloaded few images already. The problem is that there was only one nice image and the rest of them were in 95% covered with value 0 (although they were taken in the same night!).
My questions are: Is there any way to preview VIIRS Day Night Band images before download? Does mosaic of night scene images for Europe already exist and is available for download? Do you have any other ideas where to find remotely sensed images of earth at night?
Thanks for any advices!
