Description
ESA CryoSat-2 satellite data provides daily Arctic sea ice thickness, concentration, and snow depth on a 25 km grid, averaged over 30 days from September to May. The collection also includes bed topography maps of Greenland, ice thickness data from radar sounders over Greenland and Antarctica, and balance velocity calculations for the Greenland Ice Sheet during the Holocene. Data were collected as part of NASA Operation IceBridge funded campaigns and are hosted on AWS.
Use Cases
Modeling Arctic sea ice thickness trends based on CryoSat-2 derived daily estimates.
Analyzing Greenland Ice Sheet bed topography and ice thickness based on mass conservation and radar sounding data.
Studying ice freeboard and surface roughness for climate studies based on SIRAL altimeter data.
Investigating historical ice sheet balance velocity during the Holocene epoch based on calculated data.
Strengths
Includes data from the ESA CryoSat-2 satellite, a dedicated polar mission.
Combines multiple data products including sea ice parameters, bed topography, and ice thickness.
Sea ice data is provided on a defined 25 km grid with daily temporal resolution.
