CALIPSO's Infrared Imaging Radiometer provides emissivity and cloud particle data for pixels co-located with the satellite's lidar track. This Level 2 product, version 4-51, is produced by NASA and the French space agency CNES from a mission launched in 2006. The dataset supports analysis of clouds and aerosols for climate studies.
Use Cases
- Analyze cloud particle emissivity from IIR measurements to study cloud radiative effects.
- Validate climate model outputs using co-located lidar and infrared emissivity data.
- Investigate aerosol-cloud interactions by correlating IIR-derived emissivity with aerosol layers detected by CALIOP.
Strengths
- Data from a long-running joint NASA-CNES satellite mission launched in 2006.
- Product integrates co-located measurements from multiple instruments (IIR, CALIOP, WFC).
Limitations
- Specific row count, geographic coverage, and temporal resolution are not provided.
- Product version change (V4-51) was due to a cluster OS update, not a science algorithm revision.
