资源简介：
The Trace Gas Concentrations (TRGAS) suite provides key atmospheric column constituents. These trace-gas fields support both atmospheric science (e.g., air-quality and chemistry studies) and ocean-color atmospheric correction. Users should apply the quality and L2 flags to screen cloud effects, high solar-zenith conditions, and other retrieval issues before analysis.
Geophysical variables in this suite include:
- total_column_no2 – total vertical column nitrogen dioxide (molecules cm⁻²)
- total_column_o3– total vertical column ozone (Dobson units)
- l2_flags – processing flags (dimensionless)
- no2_bit_flags – NO₂ processing flags (dimensionless)
- quality_no2 – NO₂ quality flags (dimensionless)
- o3_bit_flags – O₃ processing flags (dimensionless)
- quality_o3 – O₃ quality flags (dimensionless)
