ABSTRACT: Greenhouse gas monitoring on a broader scale is necessary to ensure that
a cap-and-trade system is effective, reduces measurement uncertainty, and
detects fraudulent or illegal activities. The recent strict air quality
regulation in livestock production facilities has accelerated the need for
accurate on-farm determination of greenhouse gas (GHG) emission rates (ERs)
from livestock operations in the United States under a wide range of
production, management, and climate conditions. The estimation of GHG emissions
from different ground-level sources or at a
property line is a very complicated process, and such measurements
require multidirectional expertise including engineering, micrometeorology, agronomy, applied physics, and
chemistry. Accurate measurement of gaseous concentration from an
emitting source is a prerequisite and of paramount importance for estimating
emissions rates (ERs) using any micro-meteorological and sampling device-based
method. This paper provides an overview of the state-of-the-art sensors and
analyzers used to measure GHG concentrations. Sensor and analyzer selection and
their performance in the laboratory and field were discussed. In addition,
protocols for data quality control (QC) and quality assurance (QA) when
deploying sensors in the area for long-term use were also discussed. In
addition, the preparation of measurement systems, coupling of air samplers with
sensing systems for measuring gaseous concentrations, and uncertainties
inherent to such measurement methods as a whole to estimate ERs were discussed
in this paper.
