Spectral Outgoing Longwave Radiation (OLR) parameters derived from AIRS version 6 radiances. Data is provided monthly on a global 2x2 degree latitude/longitude grid. The algorithm was developed by Xianglei Huang at the University of Michigan using data from the Atmospheric InfraRed Sounder (AIRS) on NASA's EOS-Aqua spacecraft.
Use Cases
- Analyze spatial and temporal trends in all-sky OLR values across the 2x2 degree grid.
- Compare clear-sky OLR against all-sky OLR to isolate cloud radiative effects.
- Validate climate model outputs using spectrally resolved OLR data at 10 cm-1 bandwidth.
- Study the Earth's energy budget by integrating spectral fluxes to a single value per grid square.
Strengths
- Data derived from the established AIRS version 6 dataset.
- Provides both spectrally resolved (10 cm-1) and integrated OLR values.
- Global spatial coverage on a consistent 2x2 degree grid.
- Monthly temporal resolution for climate trend analysis.
Limitations
- Specific row count, time range, and sample size are unknown.
- Spatial resolution is coarse at 2x2 degrees for regional studies.
- Algorithmic assumptions for clear-sky retrieval may introduce uncertainty.
