TANSAT AGCS and CAPI: Satellite CO2 and Aerosol Products from 2017-2020

ESA's TANSAT satellite data products from the Atmospheric Carbon-dioxide Grating Spectrometer (ACGS) and Cloud Aerosol Polarization Imager (CAPI) instruments. The ACGS products measure CO2 mole fraction and have a temporal coverage between March 2017 and January 2020. The CAPI products observe aerosols and cloud optical properties and are available from July 2019 to January 2020.

Use Cases

• Analyze atmospheric CO2 concentrations based on ACGS spectrometer data.
• Study aerosol and cloud optical properties based on CAPI radiometer observations.
• Perform calibration and validation of satellite atmospheric measurements using the provided sample calibration products.
• Conduct time-series analysis of greenhouse gases and atmospheric components over the 2017-2020 period.

Strengths

• Data originates from two specialized satellite instruments (ACGS and CAPI) designed for atmospheric measurement.
• Provides multiple processing levels (L1A, L1B, L2) for calibration, science, and derived products.
• Covers a defined time range: ACGS from March 2017 to January 2020 and CAPI from July 2019 to January 2020.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Temporal coverage is not continuous, as noted 'not all days included in the time frame'.
• Column-level documentation is absent; field semantics must be inferred after download.
