Spectrometer and radiometer data from the GOSAT-2 satellite instruments TANSO-FTS-2 and CAI-2, archived by ESA. Products include interferograms, spectra, and column-averaged mole fractions of atmospheric gases retrieved from near-infrared and thermal infrared bands. The dataset supports atmospheric chemistry and greenhouse gas measurement.
Use Cases
- Retrieve column-averaged dry-air mole fraction of CO2 and methane from FTS-2 Level 2 products using Band 1-3 spectral radiance.
- Analyze solar-induced chlorophyll fluorescence data from the FTS-2_02_SWPR product derived from Band 1 spectral radiance.
- Study cloud and aerosol optical properties using CAI-2 Level 1A uncorrected image data from UV, visible, and near-infrared bands.
- Process interferogram data from FTS-2 Level 1A products for geometric information of observation points and telemetry.
- Compare near-real-time FTS-2 products, available 5 hours after sensing, with consolidated reprocessed products for timeliness analysis.
Strengths
- High-resolution 5-band spectrometer data from TANSO-FTS-2 for detailed atmospheric chemistry.
- Separate products for day and night observations from FTS-2 Level 1A and 1B.
- Near-real-time products available on ESA server 5 hours after sensing.
Limitations
- Specific row counts, file sizes, and temporal coverage are unknown.
- Products are generated under the assumption of clear-sky conditions, limiting applicability in cloudy regions.
- Data availability and completeness depend on reprocessing cycles, typically every 3 days.
