This dataset presents detailed coverage information derived from catalogs of CO₂ jet deposit features—fans and blotches—observed at the Martian South Pole. Generated using high-resolution HiRISE imagery from the Mars Reconnaissance Orbiter (MRO), the dataset quantifies the spatial extent and distribution of these seasonal deposits across multiple Martian years. The coverage data is crucial for understanding the dynamics of CO₂ sublimation and its interaction with surface and atmospheric processes.
The coverage metrics were calculated from annotated features compiled through contributions from the citizen science project Planet Four and advanced clustering algorithms. Each dataset entry includes coverage percentages, and the tile and image identifiers. The data spans several key regions of interest, providing insights into Martian polar processes.
This coverage dataset is a valuable resource for planetary scientists, climate modelers, and researchers focused on Martian seasonal dynamics and atmospheric coupling.
