Scientist, Plume Modeling and Forecasting

This is a fully remote position, open to applicants in California.

📋 Description

• Lead the forecasting of plumes for balloon-based tracer campaigns in collaboration with external partners.

• Create and assess plume forecasting capabilities for periods ranging from 24 to 72 hours.

• Measure forecast uncertainty and its effects on search patterns and instrument settings.

• Convert forecast results into requirements for the observing team, including viewing geometry, altitude, timing, and plume extent.

• Simulate detailed plume evolution for numerical experiments aimed at testing observing suites and sampling frequencies.

• Validate forecasts against observations from tracer campaigns and document any discrepancies.

• Manage plume-scale large-eddy and plume-resolving simulations from release to dispersion.

• Transform plume-scale outputs into dilution rates, effective source terms, and parameterizations for the global framework.

• Act as the primary point of contact for the experiment team regarding plume-scale inquiries.

• If a field study is initiated, function as the mission scientist, providing real-time forecast updates, go/no-go assessments, and guidance on sampling.

⛳️ Requirements

• A PhD in atmospheric science, fluid dynamics, or a related field, or equivalent research experience.

• Experience in running high-resolution or large-eddy simulations of dispersing materials and comparing outcomes with measurements.

• Practical forecasting or mission-science experience in an airborne or balloon field campaign.

• Proficient in Python and ideally Fortran on high-performance computing systems.

• Ability to articulate the implications of model results clearly and document findings for others.

• Exceptional written and verbal communication skills.

• Proven ability to collaborate effectively across disciplines and with external partners.

• A strong passion for Reflective's mission.

• Experience with JAX or other differentiable modeling frameworks is highly preferred.

🏝️ Benefits

• Medical, dental, and vision insurance.

• 401(k) plan.

• Opportunities for professional and personal development.

• Generous paid time off and sick leave, including 12 weeks of paid parental leave.

• Flexible working hours.

• A moving stipend to assist candidates relocating to the Bay Area.

• Access to professional learning and training opportunities.
