OMI_MINDS_NO2G: Multi-Decadal Global Nitrogen Dioxide Satellite Data

Multi-decadal data from 1996 to the present provides consistent, long-term global records of nitrogen dioxide (NO2) from multiple satellite instruments. The dataset includes tropospheric, stratospheric, and total column NO2, as well as derived surface concentrations and NOx emissions, processed to account for differences between instruments. Quality-assured Level 2 to Level 4 products are available in CF-compliant HDF5 and netCDF formats from NASA's GES DISC.

Use Cases

• Analyzing long-term trends in global and regional nitrogen dioxide pollution based on multi-satellite records.
• Estimating surface-level NO2 concentrations and NOx emissions using derived Level 4 data products.
• Studying changes in atmospheric composition over two decades by comparing data from GOME, SCIAMACHY, OMI, GOME-2, and TROPOMI instruments.
• Validating air quality models and emission inventories with gridded, global 0.25-degree resolution satellite observations.

Strengths

• Provides a consistent, trend-quality record spanning over two decades (from 1996 to present).
• Integrates data from five major satellite instruments (GOME, SCIAMACHY, OMI, GOME-2, TROPOMI), systematically accounting for instrumental differences.
• Includes value-added data products like Level 4 surface NO2 concentrations and NOx emissions.

Limitations

• Specific column names, row counts, and dataset size are not provided in the available metadata.
• License information is inconsistent across sources, listed as 'other-license-specified' on some platforms and 'None' on others.
• The last update date (2026-03-13) appears to be a future date, which may indicate a metadata error.
