56 pixels per scan line provide calibrated brightness temperature data from 26 spectral channels for Earth observation. The dataset includes geographic coordinates, land-sea mask, surface elevation, and solar and satellite viewing angles. SCIOPS produced this Level 1 product from FY-3A IRAS raw data after quality control, navigation, and calibration.
Use Cases
- Validate atmospheric temperature profiles by analyzing brightness temperature from 26 infrared spectral channels.
- Map land surface characteristics using land-sea mask, land cover, and surface elevation data per pixel.
- Correct for viewing geometry in radiative transfer models using satellite zenith and azimuth angles.
- Assess data quality for downstream processing by applying the included quality flags of the processing.
- Perform cross-calibration with other instruments using lab calibration coefficients for VIS-NIR channels.
Strengths
- Includes 26 spectral channels providing multi-band infrared observations.
- Contains calibration coefficients for both VIS-NIR and infrared channels.
- Provides per-pixel geographic data including latitude, longitude, and surface elevation.
- Includes quality flags to indicate the reliability of processed data.
Limitations
- Specific row count, temporal coverage, and spatial extent are unknown.
- The dataset description does not specify the resolution or frequency of observations.
- Unknown if the dataset includes atmospheric correction or cloud masking.
