Sentinel-1 HH+HV backscatter statistics for five Antarctic ice shelves 2019–2025 — Version 2 Dataset for Shobha Mourya Dumpati (2026)

Version 2 (July 2026): Corrected README.txt (fixed masking description, IceLines DOI, folder structure, added systematic calibration offset disclosure and bounding box contamination notes). Corrected Dumpati_2026_Antarctic_Brine_SAR_Processing.py (fixed column naming mismatch between code and deposited CSV, added rasterio version compatibility fix, removed unused imports, added systematic calibration offset documentation). All data files and statistics are unchanged.
