The Los Angeles basin is a very large source of the important greenhouse gases CO₂, CH₄ and N₂O, and pollutants such as CO and aerosols. Recent legislation in California, such as the Global Warming Solutions Act (AB32), has mandated progressive reductions in statewide greenhouse gas emissions. Verifying the effectiveness of greenhouse gas controls requires frequent, high-precision measurements over a large area combined within a modeling framework to account for the efffects of atmospheric transport and to convert measured atmospheric abundances into emission rates.

To address this requirement, we have developed an innovative mountaintop observatory, California Laboratory for Atmospheric Remote Sensing (CLARS), that uses high-resolution infrared spectrometers to survey the spatial and temporal distributions of greenhouse gases and pollutants in Los Angeles. In continuous operation since 2011, CLARS is a unique facility that has resulted in numberous publications on greenhouse gases, pollutants, aerosol physics and remote sensing technology.

We seek motivated applicants with backgrounds in fields such as atmospheric modeling, remote sensing, geographical information systems, spectroscopy and instrumentation.
