SMEX03 ASTER Level-1B Infrared and Visible Mosaics for Oklahoma

Oklahoma North and South regional study areas are covered by mosaicked Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Level-1B images. Data originates from the NASA NSIDCV0 organization and was last updated in March 2026. This dataset provides calibrated radiance data in visible and infrared wavelengths.

Use Cases

• Analyzing land surface temperature and thermal properties using thermal infrared radiance data.
• Studying surface reflectance and albedo from calibrated visible radiance measurements.
• Regional land cover classification and change detection by comparing spectral signatures across infrared and visible wavelengths.
• Validating soil moisture models and estimates as part of the SMEX03 field campaign context.

Strengths

• Data provides calibrated radiance in multiple spectral bands, including visible and thermal infrared.
• Images are mosaicked for two defined regional study areas (Oklahoma North and South), ensuring spatial consistency.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata and Data.gov), indicating established provenance.

Limitations

• Specific column names, row counts, and file sizes are not documented across any source.
• Sources conflict on license details, with one specifying 'other-license-specified' and another listing 'None'.
