MARINE OBSERVATION SOURCE · S042
NASA NSIDC DAAC
Discover marine observations available through NASA NSIDC DAAC, including parameters, platforms, spatial and temporal coverage, metadata, and access methods.
- Operator
- NASA National Snow and Ice Data Center Distributed Active Archive Center
- Role
- Cryosphere satellite/archive + granule discovery
- Platforms
- ICESat-2/ATLAS; CryoSat-2/SIRAL; supporting satellite/model products
- Observed variables
- Sea-ice freeboard, sea-ice thickness, sea-ice elevation, snow depth/density, sea-ice concentration and related cryosphere products
- Spatial coverage
- Polar/global depending product; marine use primarily Arctic/Antarctic sea ice
- Period
- Mission/product dependent; ICESat-2 2018-present; CryoSat-2 products 2010-2025
- Depth coverage
- Sea-ice surface/freeboard/thickness; not a water-column depth profile
- QC and data mode
- Mission/product-specific validated processing; versioned products
- Access method
- Discover dataset/granules through NSIDC/Earthdata; filter by space/time; use Earthdata cloud/direct download for files
- Indexed download targets
- 8

Discovery and access
Add as a first-class cryosphere connector. Index dataset/granule footprints and processing level; do not treat Level-4 thickness analyses as raw direct measurements.
