Graduate Research Scientist intern

Job Description:

AMA is seeking a graduate level Research Scientist intern to support cryospheric remote sensing research at NASA Langley Research Center (LaRC), contributing to a feasibility study that integrates multi angle polarimetry, radiative transfer modeling, and machine learning based retrievals to advance instrument concept development for future Earth observing missions.

The hourly rate for this position is $27.69-$33.85 determined by level of education and relevant skills and experience. Remote work is an option.

Key Responsibilities

• Conduct a feasibility analysis for a passive multiangle polarimeter designed to retrieve sea ice albedo and related cryospheric variables.

• Extend the published RTMSciML framework (Zhou et al., 2023, 2025) to incorporate polarized radiance and dense angular sampling.

• Produce a synthetic training dataset of topofatmosphere Stokes vectors using a vector radiative transfer model across representative sea ice surface conditions.

• Train and evaluate ML models to retrieve broadband shortwave albedo and melt pond fraction.

• Quantify retrieval performance across spectral, angular, and polarimetric configurations using heldout synthetic test data.

• Document tradeoffs between spectral range, angular sampling, and polarimetric capability.

• Deliver recommendations for multiangle polarimeter instrument design.

• Prepare clear documentation, written reports, and oral presentations summarizing methods and findings.

Required Qualifications

• Bachelor's in Physics, Atmospheric Science, or a related field.

• Strong Python skills, including NumPy and SciPy.

• Experience with a machine learning library such as PyTorch or TensorFlow.

• Ability to work with large multidimensional scientific datasets.

• Experience with radiative transfer modeling; familiarity with vector RT codes such as AccuRT, libRadtran, SCIATRAN, or VLIDORT.

• Ability to work independently and document code and methodology clearly.

• Strong written and oral communication skills.

Desired Qualifications

• Background in atmospheric or cryospheric remote sensing.

• Experience or coursework related to optical instrument design or polarimetry.

• Familiarity with polarimetric measurements and their applications.

• Interest in contributing to a peerreviewed publication.

• Enthusiasm for instrument concept development for current and future Earthobserving missions.
