MODIS Satellite Data for Cold Land Processes Field Experiment

CLPX-Satellite: MODIS Radiances, Reflectances, Snow Cover and Related Grids, Version 1 provides Moderate Resolution Imaging Spectroradiometer (MODIS) data collected for the Cold Land Processes Field Experiment. The dataset includes parameters such as radiances, surface reflectance, snow cover, land surface temperature/emissivity, and vegetation indices. It is produced by the National Aeronautics and Space Administration, with metadata indicating activity around 2003.

Use Cases

• Analyzing spatial and temporal patterns of snow cover using the snow cover parameter.
• Modeling land surface energy balance with land surface temperature/emissivity data.
• Assessing vegetation health and phenology in cold environments via vegetation indices.
• Calibrating surface reflectance models for remote sensing applications.
• Studying radiative properties of land surfaces using radiance and surface reflectance data.

Strengths

• Data originates from the MODIS instrument, a well-established NASA satellite sensor.
• Covers multiple key geophysical parameters relevant to cold land processes.
• Dataset is hosted on multiple government platforms, indicating institutional importance.

Limitations

• Critical metadata conflicts exist: the last updated date differs significantly between sources (2003 vs. 2026).
• Specific row counts, file sizes, and detailed column names are not provided by any source.
• The license is ambiguously listed as 'other-license-specified' without clear terms.
