ABoVE: CO2 and CH4 Fluxes and Meteorology from Five Alaskan Tower Sites, 2015-2017

Five eddy covariance tower sites along a 300-km north-south transect on Alaska's North Slope provide half-hourly measurements of CO2, CH4, and H2O fluxes, sensible and latent heat fluxes, and meteorological parameters. The dataset covers the period from January 1, 2015, to March 9, 2017. It was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Modeling net ecosystem exchange (NEE) of CO2 based on half-hourly flux measurements.
• Analyzing methane (CH4) emission patterns across a latitudinal gradient based on data from five tower sites.
• Studying surface energy balance using sensible heat, latent heat, and ground heat flux data.
• Investigating relationships between greenhouse gas fluxes and meteorological drivers like air temperature, radiation, and soil moisture.

Strengths

• Data from five sites forming a 300-km transect provides spatial coverage across Alaska's North Slope.
• Half-hourly temporal resolution for fluxes and meteorology from 2015-01-01 to 2017-03 09.
• Includes multiple flux types (CO2, CH4, H2O, sensible/latent heat) and a suite of meteorological parameters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
