AIRS_CPR_MAT: Collocated Satellite Cloud and Radiance Data from the A-Train

AIRS_CPR_MAT collocates radiances, radar reflectivities, and cloud masks from multiple A-train satellite instruments, including AIRS, CloudSat, and MODIS. The dataset is produced by NASA's National Aeronautics and Space Administration under the MEaSUREs project to develop a multi-sensor water vapor climatology. Parameters include cloud fraction, radar reflectivity, layer heights, and spectral radiances.

Use Cases

• Classifying atmospheric scenes based on cloud information from the MODIS cloud mask and CPR Cloud Mask.
• Analyzing vertical cloud structure based on CloudSat radar reflectivity and layer top/base heights.
• Developing multi-sensor water vapor climatologies stratified by cloud classes using collocated AIRS radiances.
• Validating satellite retrievals using matchups between AIRS, MODIS, and CloudSat instruments.

Strengths

• Data is collocated from multiple high-profile satellite instruments (AIRS, CloudSat, MODIS) within the A-train constellation.
• Contains over 15 specific parameters for atmospheric analysis, including cloud fraction, radar reflectivity, and spectral radiances.
• Created under NASA's MEaSUREs project, indicating a structured, science-driven methodology.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale machine learning tasks.
• Column-level documentation is absent; field semantics must be inferred after download from the parameter list.
