Atmospheric Infrared Sounder (AIRS) Level 3 daily support product provides gridded atmospheric data from the EOS Aqua satellite. The data includes fields that are not fully validated or are intermediary values, and values from failed retrievals may be present. It is produced by the GES DISC and contains daily global coverage at a 1 degree by 1 degree spatial resolution.
Use Cases
- Analyze unvalidated atmospheric variables for research prototyping based on the description of fields not fully validated.
- Study global atmospheric composition and trends based on daily gridded infrared spectrometry data.
- Incorporate intermediary sensor values into data assimilation models based on the mention of inputs or intermediary values.
- Compare standard and support products to understand validation impacts based on the description of similarity to L3 standard products.
Strengths
- Data is derived from the AIRS grating spectrometer with a resolution of R=1200, as stated in the description.
- Provides daily global coverage at a consistent 1x1 degree spatial resolution.
- Includes data from a sensor suite combining visible, infrared, and microwave sensors (AIRS, AMSU, HSB).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may include values from failed retrievals as no quality control information is available for some fields.
