Job Description And Duties
Under supervision of the Land and Climate Science Section (LCSS) Air Resources Supervisor I (ARSI), the Staff Air Pollution Specialist (SAPS) will lead comprehensive research projects to improve our understanding of direct and indirect interactions among air quality, climate, and natural and working lands (NWL) at the state, national, and international levels. The SAPS will focus on advancing methodologies for tracking greenhouse gas (GHG) emissions and reductions, carbon sequestration, and other co-benefits from NWL. This work is essential for demonstrating progress toward the 2045 carbon neutrality target. The SAPS will work closely with program divisions working on emission inventories, nature-based climate solutions (e.g., carbon sequestration), regulatory ambient air monitoring (e.g. emergent toxics and particulate matter (PM2.5)), regional air quality modeling, and community air protection to support programs surrounding Assembly Bill (AB) 1757, AB 617, the Scoping Plan, and the State Implementation Plans. The SAPS will work closely with diverse interested parties, including the California Natural Resources Agency (CNRA), the California Department of Food and Agriculture (CDFA), the California Environmental Protection Agency (CalEPA), the California Department of Forestry and Fire Protection (CalFIRE), National Oceanic and Atmospheric Administration (NOAA). Research topics will evolve based on the agency’s research needs, offering an opportunity to inform and support CARB programs. The SAPS is expected to use effective communication to build strong internal and external partnerships to formulate impactful research that aids state programs and advances science nationally and internationally. Additional duties include stakeholder engagement, contract management, research planning, writing reports, data analysis, presentations to technical and non-technical stakeholders, and travel may be required.
Candidates should have experience using common open-source scientific programming languages such as R or Python to perform quality control environmental data. Candidates should have knowledge of process-based models in NWL (e.g., Regional Hydro-Ecologic Simulation System (RHYSSys), Cohort Wetlands Equilibrium Model (CWEM), Peatland Ecosystem Photosynthesis Respiration and Methane Transport (PEPRMT), DeNitrification-DeComposition (DNDC), Model of Emissions of Gases and Aerolsols from Nature (MEGAN)-Berkeley-Dalhousie Soil NOx Parameterization (BDNSP), Simplified Photosynthesis and Evapotranspiration (SIPNET) or other process-based models). Candidates should have experience working on high performance computing systems in a Linux-based environment or the equivalent. Candidates will be expected to learn and contribute to development of existing and new models. They will also be expected to maintain clean, well-documented, reproducible code bases for their work. Communication with internal and external stakeholders will be an important part of the position, and candidates will be expected to lead coordination with project stakeholders during the project planning stages. Candidates should be able to synthesize their work into clear, concise presentations and reports tailored to various audiences. They should have experience publishing scientific, peer-reviewed literature and drafting research proposals.
