SNOE UVS: Nitric Oxide Density in Earth's Upper Atmosphere

SNOE UVS (Ultraviolet Spectrometer) data contains nitric oxide volume density measured at Earth's limb. Density data are provided from 100 to 150 km altitudes in 10 km intervals, recorded in 5-degree bins of geomagnetic latitude and longitude. The dataset was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Model nitric oxide distribution in the thermosphere based on altitude and geomagnetic coordinates.
• Analyze the relationship between geomagnetic location and atmospheric density based on the 5-degree binning.
• Validate atmospheric models using interpolated density data across altitude levels.
• Study satellite limb observations of Earth's atmosphere for remote sensing applications.

Strengths

• Data is interpolated to fill single-point outages, likely improving continuity.
• Altitude resolution is specified as 10 km intervals from 100 to 150 km.
• Geomagnetic coordinates are recorded in 5-degree bins, providing a structured spatial grid.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is March 2026.
