TIRAuxCloud: A Thermal Infrared Dataset for Day and Night Cloud Detection

TIRAuxCloud is a multi-modal dataset designed to support all day cloud segmentation, with a particular focus on thermal infrared (TIR) imagery. It combines multispectral observations from Landsat and VIIRS with auxiliary information such as elevation, land cover, meteorological variables, and cloud-free reference imagery. The dataset includes both automatically generated cloud masks and manually annotated samples, enabling the development and evaluation of advanced cloud detection methods.
