SNDRJ1IML2CPS: JPSS-1 Atmospheric State Profiles

CLIMCAPS uses 2211 infrared channels and 22 microwave channels from the NOAA-20 satellite to retrieve full atmospheric profiles. Its Optimal Estimation method relies on MERRA-2 reanalysis, resulting in a latency of 3 to 7 weeks. Each Level 2 granule contains 30 footprints cross-track by 45 lines along-track, with 240 granules produced daily.

Use Cases

• Monitoring global atmospheric profiles of temperature, water vapor, and ozone for climate studies.
• Tracking trace gas concentrations like carbon monoxide, methane, and sulfur dioxide for air quality research.
• Analyzing infrared effective cloud top characteristics for cloud property and radiative studies.
• Assessing surface temperature and emissivity for land surface and ocean temperature applications.

Strengths

• Provides full atmospheric state profiles derived from 2211 spectral channels of the CrIS instrument.
• Couples infrared and microwave data from the CrIS/ATMS suite for improved retrieval accuracy.
• Generates 240 granules per day, offering frequent global coverage from the NOAA-20 satellite.

Limitations

• Product latency is 3 to 7 weeks due to dependency on MERRA-2 reanalysis data.
• Specific column names and dataset size metrics are not provided in the available metadata.
• The license is listed as 'other-license-specified' without further details.
