GOME_MINDS_NO2: Multi-Decadal Satellite Nitrogen Dioxide Columns

Multi-decadal records from 1996 to present provide tropospheric, stratospheric, and total nitrogen dioxide (NO2) column data from multiple satellite instruments. This dataset is part of NASA's MEaSUREs program, created by the MINDS project to produce consistent, long-term, trend-quality data records. It is hosted by NASA's GES DISC and made available in CF-compliant HDF5 and netCDF formats.

Use Cases

• Modeling long-term global NOx emission trends based on multi-satellite data records.
• Analyzing changes in tropospheric NO2 columns over regions with shifting industrial activity.
• Validating air quality models using satellite-derived surface NO2 concentration estimates.
• Studiating atmospheric chemistry by comparing stratospheric and total NO2 column data.

Strengths

• Data spans over two decades, covering a period of remarkable change in NOx emissions.
• Integrates measurements from five satellite instruments (GOME, SCIAMACHY, OMI, GOME-2, TROPOMI) for consistency.
• Provides Level 2 swath data, Level 3 gridded columns, and Level 4 value-added products like surface concentrations and emissions.

Limitations

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