Column measurements of NO2, O3, and HCHO were collected by Pandora instruments during the 2016 KORUS-AQ field study. The dataset was created by NASA and Korea's National Institute of Environmental Research (NIER) to investigate air quality factors in South Korea. Data collection was completed in 2016.
Use Cases
- Analyze temporal trends in NO2, O3, and HCHO column densities from specific ground sites like NIER-Taehwa or Yonsei University.
- Validate satellite-derived air quality products using ground-based Pandora column observations.
- Model relationships between different pollutant columns (NO2, O3, HCHO) across the Seoul Metropolitan Area and other study sites.
- Assess spatial variability of formaldehyde (HCHO) columns across the eight listed ground measurement locations.
- Investigate diurnal or seasonal patterns in ozone (O3) column data collected during the May-June 2016 campaign.
Strengths
- Data originates from a major, coordinated international field campaign (KORUS-AQ) sponsored by NASA and NIER.
- Measurements cover eight distinct ground sites across South Korea, providing spatial context.
- Collection period is precisely defined as May-June 2016.
Limitations
- Dataset temporal coverage is limited to a two-month campaign in 2016, not ongoing.
- Sample size and row count are unknown, limiting assessment of statistical power.
- Geographic scope is focused on South Korea, limiting generalizability to other regions.
