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.
- Long-term field sites outside major urban centers in Central (San Francisco and Sacramento) and Southern California (San Bernardino)
- Continuous full-suite GHG (CO2, CH4, N2O, CO), and/or periodic flask (e.g., 14CO2, 13CO2, 13CH4) measurements
- Mobile field measurement capabilities include instrumented aircraft, balloon borne full column GHG sampling, and mobile plume integrator survey (MPI) instrument
- Laboratory measurements of all major GHGs (CO2, CH4, N2O, CO) and selected stable isotopes (13CO2, 13CH4) for secondary reference gas calibration
