CrIMSS SiFSAP: High-Resolution Atmospheric Profiles per Footprint

Suomi NPP satellite data provides global atmospheric profiles retrieved from infrared and microwave sounder measurements. The SiFSAP algorithm generates Level-2 products with temperature, water vapor, trace gas species, cloud, and surface property profiles at a higher spatial resolution than other current IR sounder products. Each granule covers 6 minutes of data, with 240 granules produced daily and an orbit repeat cycle of approximately 16 days.

Use Cases

• Analyzing vertical temperature profiles based on the 27-level retrieval variable.
• Studying cloud optical depth and microphysics based on the cloud properties variable.
• Monitoring trace gas species like methane and ozone based on the atmospheric chemistry variables.
• Assessing surface thermal properties based on the land surface skin temperature variable.
• Calculating total precipitable water based on the water vapor profile variable.

Strengths

• Offers 3-times higher horizontal spatial resolution than other current IR sounder products.
• Provides 9-time denser products due to retrieval per Field of View (FOV).
• Contains profiles for water vapor at 11 levels and other variables up to 27 levels.

Limitations

• Specific column names and dataset size are not provided in the metadata.
• The license is ambiguously labeled as 'other-license-specified' without details.
• Metadata for rows, size, and author is consistently missing across platforms.
