SNDRJ1IML3CMCCP: Monthly Global Atmospheric Profiles from JPSS-1 Satellite

Global monthly gridded data provides a full atmospheric state derived from the NOAA-20 (JPSS-1) satellite's CrIS/ATMS instrument suite. The CLIMCAPS algorithm retrieves profiles of temperature, water vapor, ozone, and trace gases like carbon monoxide and methane, alongside surface and cloud properties. This Level-3 product has a spatial resolution of one degree latitude by one degree longitude.

Use Cases

• Monitoring global carbon monoxide distributions, with correction for a known bias in the 'co_mmr_midtrop' variable.
• Analyzing vertical profiles of temperature and water vapor for weather and climate model validation.
• Tracking greenhouse gas concentrations, including methane and carbon dioxide, on a global scale.
• Studying cloud top characteristics and their relationship to atmospheric thermodynamics.
• Assessing surface skin temperature and land surface emissivity for land-atmosphere interaction studies.

Strengths

• Derived from high-resolution satellite instrumentation, specifically the CrIS spectrometer with 2211 infrared channels and the ATMS scanner with 22 microwave channels.
• Provides a multi-parameter atmospheric state, including profiles for multiple trace gases and cloud properties.
• Issued with a detailed warning and correction procedure for a specific data error ('co_mmr_midtrop'), indicating active quality oversight.

Limitations

• Contains a significant, documented bias in the 'co_mmr_midtrop' variable requiring user correction.
• Key metadata such as row count, column names, and specific temporal coverage are unavailable across all sources.
• License is ambiguously specified as 'other-license-specified' without clear terms.
