CLDPROPCOSP_D3_MODIS_Aqua: Daily Global Cloud Properties

Global daily satellite data from the MODIS/Aqua instrument provides cloud mask, cloud top, and cloud optical retrieval information on a 1x1 degree grid. The dataset contains 32 aggregated science parameters designed for direct comparison with climate model output via the CFMIP Observation Simulator Package (COSP). Its collection began on July 4, 2002, and continues with 365 granules per calendar year.

Use Cases

• Validating cloud parameterizations in climate models based on aggregated satellite observations.
• Analyzing global cloud frequency and distribution patterns over daily timeframes.
• Comparing cloud optical depth and microphysical properties against model simulations.
• Studying cloud top pressure and height variability for atmospheric process studies.

Strengths

• Contains 32 specific science data sets (SDS/parameters) for detailed cloud analysis.
• Provides a long-term, consistent record starting from July 4, 2002.
• Specifically designed for the CFMIP Observation Simulator Package (COSP), enhancing comparability with climate models.

Limitations

• Key metadata such as row count, file size, and specific column names are not provided on any platform.
• License information is inconsistently reported as 'other-license-specified' on Data.gov but 'None' on NASA Earthdata.
• Documentation is referenced but not directly linked, requiring users to locate the CLDPROPCOSP User Guide separately.
