NARSTO EPA Supersite Baltimore: Meteorological and Turbulence Data from 2001-2003

Three Baltimore locations were monitored between May 26, 2001 and March 15, 2003, collecting meteorological and turbulence data. The dataset contains 5-minute averaged measurements from instruments including sonic anemometers, pyranometers, and humidity probes, validated for correctness. It was produced by the Parlange Environmental Fluid Mechanics Group at Johns Hopkins University for the EPA PM Supersites Program.

Use Cases

• Model urban atmospheric stability based on the Obukhov length parameter.
• Analyze wind patterns and turbulence for dispersion modeling based on friction velocity and wind angle data.
• Correlate meteorological conditions with particulate matter (PM) data for health exposure studies.
• Study diurnal cycles of solar radiation, temperature, and humidity in an industrial urban setting.

Strengths

• Data underwent multiple cycles of validation to ensure correctness and accuracy.
• Provides high-temporal-resolution 5-minute averaged data for variables like temperature, wind speed, and solar radiation.
• Includes specialized turbulence parameters (friction velocity, Obukhov length) alongside standard meteorological measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a specific historical period (2001-2003) and three urban locations, which may limit generalizability.
