Freeze/Thaw Data Access and Tools
Data from NASA range from daily composites of global landscape freeze/thaw conditions to daily thaw state maps of Boreal and Arctic Alaska. Our datasets and tools help users find and integrate the data they need to measure and understand freezing and thawing processes within Earth’s cryosphere.
