MAIA Surface Monitor: Global Particulate Matter Measurements

NASA's Atmospheric Science Data Center processes particulate matter measurements from a global in-situ surface monitoring network. The MAIA Surface Monitor Stage 0 files contain these processed PM data as an ancillary dataset. Columns likely include time-series measurements of PM concentrations from monitoring stations worldwide.

Use Cases

• Validating satellite-based air quality observations using ground-based in-situ measurements.
• Analyzing temporal trends in particulate matter concentrations across a global monitoring network.
• Assessing regional air quality and pollution exposure based on processed PM data.

Strengths

• Data is processed and curated by NASA's Atmospheric Science Data Center, indicating a high level of quality control.
• The dataset leverages a global in-situ monitoring network, suggesting broad spatial coverage.

Limitations

• Column names and specific data types are not provided in any source, limiting understanding of the data structure.
• Sources disagree on metadata completeness, with some listing no tags, size, rows, license, or author.
