GOZCARDS Merged Nitrous Oxide Satellite Data on a Vertical Pressure Grid

Merged N2O measurements from ACE-FTS and Aura MLS satellite instruments, spanning from 2004 onward. The data provides zonal averages, standard deviations, and min/max values on a vertical pressure grid from 147 to 0.5 hPa. NASA distributes this merged product in netCDF4 format.

Use Cases

• Analyzing long-term trends in atmospheric nitrous oxide based on merged satellite records.
• Validating climate and chemistry models using zonal mean N2O concentrations.
• Studying the vertical distribution of N2O across pressure levels from 147 to 0.5 hPa.
• Assessing instrument bias and data consistency between ACE-FTS and Aura MLS sources.

Strengths

• Data merges two established satellite instrument sources (ACE-FTS v2.2u and Aura MLS v3.3).
• Covers a vertical pressure range from 147 to 0.5 hPa.
• Includes derived statistics like zonal means, standard deviations, and minimum/maximum values.

Limitations

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