AIRSAC3MNH3 V3: Atmospheric Ammonia Measurements from NASA Aqua Satellite

Monthly measurements of atmospheric ammonia volume mixing ratio derived from the AIRS/AMSU instrument on NASA's Aqua satellite. The data covers September 2002 through August 2016 and is produced by NASA for studying the global nitrogen cycle and aerosol formation. Ammonia sources include agricultural activities, and its measurement aids in monitoring global atmospheric composition.

Use Cases

• Modeling global nitrogen cycles based on ammonia concentration data
• Studying aerosol formation and cloud condensation nuclei based on ammonia's reaction with acids
• Monitoring agricultural emissions and their atmospheric impact based on ammonia source descriptions
• Analyzing long-term trends in atmospheric composition based on the 14-year time series

Strengths

• Data spans 14 years from September 2002 to August 2016
• Provides global monitoring of atmospheric ammonia, a component with sparse ground measurements
• Produced by NASA, a recognized authoritative source for satellite data

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
