  • Build fixtures, test equipment, data-acquisition workflows, and analysis software needed for validation.
  • Help design laboratory, ground, and flight comparisons against reference instrumentation.
  • Connect physical instrument behavior to measurement and retrieval quality.
  • Produce clear documentation, calibration records, acceptance criteria, and reusable analysis code.
  • Deliver a final artifact such as a validated dataset, calibration system, instrument prototype, test method, uncertainty analysis, or technical report.

Qualifications

  • Current undergraduate, master's, or PhD students; postdoctoral researchers; recent graduates; and other early-career researchers are all eligible.
  • Background in optical engineering, mechanical engineering, electrical engineering, physics, atmospheric science, experimental science, or a related field.
