SNDRSNIML3CDCCPN: Daily Atmospheric Profiles from Suomi NPP Satellite

CLIMCAPS algorithm data provides daily, one-degree gridded atmospheric profiles derived from the Suomi NPP satellite's CrIS/ATMS instruments. The dataset includes full atmosphere profiles of temperature, water vapor, ozone, and trace gases like carbon monoxide, methane, and sulfur dioxide, alongside surface and cloud properties. It is produced using an Optimal Estimation methodology applied to infrared and microwave sounding data.

Use Cases

• Monitoring global carbon monoxide levels using retrieved column density values ('mol_lay/co_mol_lay').
• Analyzing cloud top characteristics and vertical distribution for weather and climate models.
• Studying surface skin temperature and emissivity for land surface process research.
• Tracking profiles of water vapor and ozone for atmospheric dynamics and composition studies.
• Investigating trace gas distributions (methane, sulfur dioxide, nitric acid) for pollution and greenhouse gas research.

Strengths

• Derived from high-resolution satellite instruments: CrIS has 1305 infrared channels and ATMS has 22 microwave channels.
• Provides a comprehensive atmospheric state characterization, including profiles of multiple gases and cloud properties.
• Algorithm uses Optimal Estimation methodology, a recognized approach for remote sensing retrievals.

Limitations

• A significant bias exists in the derived product 'co_mmr_midtrop' due to a molecular weight conversion error.
• Key metadata such as row count, column names, and exact file size are unavailable across all sources.
• The dataset's temporal coverage and spatial resolution beyond 'daily one degree' are not explicitly stated.
