Even so, such satellite data merging is complicated by the fact that each individual satellite observation represents a single 'snapshot' of the cloud patterns, each taken at slightly different times, whereas the underlying clouds themselves are constantly moving and evolving.
Kljub temu so takšni združeni satelitski podatki zapleteni, saj vsak satelit posreduje posnetke vzorcev oblakov, ki jih posname ob različnih časovih. Oblaki se pa neprestano premikajo in spreminjajo.
