Anthropogenic Emissions

Anthropogenic Emissions

The California Greenhouse Gas Emissions Measurement Project (CALGEM) currently comprises a full-scope combination of field sites, measurement instrumentation, and numerical modeling as a user facility for quantification of anthropogenic greenhouse gas emissions of individual facilities to air basin scales.

Measurements

Modeling

  • Spatiotemporally explicit bottom-up estimates for California methane emissions
  • Atmospheric transport simulation using the National Center for Atmospheric Research (NCAR) Weather Research Forecasts (WRF) at 1 kilometer resolution in domains over California
  • Stochastic Time Inverted Lagrangian Transport (STILT) model calculations receptor footprints
  • Inverse emissions estimation capabilities including linear and hierarchical Bayesian, as well as geo-statistical inverse models
  • Evaluation of predicted transport using wind velocity and boundary layer depth and turbulence data from using network data from radar wind profilers
