A representative subset of all-sky image data is provided for demonstration and benchmarking purposes. The collection includes example sequences from clear-sky days (12/13/14.6) and broken-sun (intermittently cloud-obscured) days in order to illustrate typical irradiance variability and challenging cloud dynamics. Due to a 50 GB storage limitation, the upload does not contain the full dataset; only selected days and time windows are included. Images were acquired with an embedded camera pipeline; ISP denotes the Image Signal Processor used for in-camera processing (e.g., demosaicing and tone mapping, depending on the capture mode). In addition to processed image products, .npz files contain RAW capture data (multi-exposure RAW series and associated metadata) intended for reproducible HDR reconstruction and algorithmic evaluation.
