We are recruiting for either an Assistant Air Quality Specialist or Air Quality Specialist (AQMP/SIP Modeling/Inventory Unit & Air Quality Assessment Unit) for the AQMP/SIP Modeling/Inventory unit and the Air Quality Assessment unit of our Planning, Rule Development, and Area Sources (PRDAS) division, a major branch of SCAQMD.  An eligible list of candidates established with this recruitment can be used to fill a current and future Assistant Air Quality Specialist/Air Quality Specialist vacancies in our Planning, Rule Development, and Area Sources Division (PRDAS).
Activities within the AQMP/SIP Modeling/Inventory unit include air quality analysis and numerical modeling of meteorology and photochemistry, emissions inventory development,
processing big data such as satellite retrieved data and low cost sensor data, image processing, development/implementation of the Net Emissions Analysis Tool for evaluating energy efficiency projects, air quality evaluation and forecasting and other functions of the PRDAS division.

Activities within the Air Quality Assessment unit include performing complex analyses of large measured meteorological and air quality data sets from ground- and satellite-based measurement platforms, air quality forecasting, point-source modeling, rule making, addressing air quality related inquiries from the public, identification of data to exclude due to exceptional air quality events, preparing reports and presentations related to air quality and meteorology, graphical information system analysis, and conducting highly-applied air quality research.

Specialized duties for the current vacancies include:

  • Conduct comprehensive three-dimensional chemical transport modeling to assist in policy decisions, air quality management plans, rule making activities and other special studies
  • Prepare spatially and temporally allocated emissions inventories as input for photochemical transport modeling
  • Perform complex air quality and meteorological data analysis
  • Prepare research reports and publications based on air quality modeling and monitoring studies
  • Conduct point-source modeling and review point-source modeling studies
  • Develop and/or administer maintenance and upgrades of Linux-based parallel computing systems
  • Prepare and/or perform presentations to convey complex air quality concepts to technical and/or general-public audiences
  • Perform air quality forecasting
  • Collaborate with other government agencies, academic institutions and other professional communities
  • Analyze information and data leading to the preparation of written documents such as findings and recommendations, exceptional event analyses, rule drafts and supporting documents, reports, graphs, charts and statistical summaries
  • Conduct highly-applied air quality research to support the mission of the agency
  • Perform various other tasks unique to the unit
