Remote Sensing Scientist

Global Science & Technology, Inc., a fast growing scientific and high technology firm, is seeking a CrIS Remote Sensing Scientist to support the NOAA NESDIS/STAR program. The position is in College Park, MD.

Position Summary:

GST seeks a highly motivated candidate for a position to support the Cross-track Infrared Sounder (CrIS) Sensor Data Record (SDR) Algorithm Calibration and Validation Science Team (ACVST) led by NOAA/NESDIS/STAR. As a member of the CrIS SDR ACVST, the incumbent will develop tools and perform analysis for the calibration and validation of the CrIS instrument. The CrIS sensor is a Fourier Transform Spectrometer currently flying on-board the Suomi National Polar-orbiting Partnership (SNPP) and NOAA-20 spacecraft, and planned for the JPSS-2, -3 and -4 satellites. The CrIS SDR ACVST has the responsibility of the science algorithms for transforming the CrIS raw data records (RDR) into high quality geolocated and calibrated radiance product called the SDR. This position involves the participation in pre-launch and post-launch calibration and validation activities of CrIS observations.

Duties:

• Develop, test and evaluate the different components of the operational CrIS SDR calibration algorithm.
• Support radiometric, spectral, and geometric calibration and validation of CrIS observations
• Monitor CrIS performance
• Develop, improve and implement methodologies for the radiometric, spectral, and geometric calibration and validation of CrIS observations.
• Disseminate analysis results to calibration specialists, higher level product developers, instrument vendors, instrument operators, project managers, international partners, and other appropriate stakeholders.
• Support JPSS-2 Pre-launch, Post-launch activities, and the JPSS-2 Beta and Provisional Maturity Reviews.
• Support anomaly detection, characterization, and resolution.
• Investigate, monitor and derive solutions for potential anomalies related to CrIS instruments.
• Investigate root causes of anomalies.
• Work with the CrIS team to archive the history of performance and quality
• Support IR sounder activities
• Publishing research results in peer-reviewed journals.
• Participate in conferences.

Required Education/Experience/Skills:

• A Master's degree (Ph.D. preferred) in Atmospheric Sciences, Physics, Aerospace Engineering, Remote Sensing, Electrical Engineering, Signal Processing or a related physical science.
• Broad knowledge of physical basis of remote sensing.
• Experience with analyzing satellite data. Knowledge and experience with atmospheric sounding products are a plus.
• Familiarity with radiative transfer models, including the LBLRTM and CRTM models.
• Preferred experience on following programming languages: C/C++, Fortran 90/95, Python, Matlab, IDL, Shell scripting.
• Familiarity with GitHub and GitLab.
• Experience working in Linux environment.
• Excellent oral, written and interpersonal communication skills.
• Experience in Optics, such as Interferometry.
• Experience with Fourier Transform Spectrometers.
• Experience with Hyperspectral Infrared Observations.
• Experience with Data Science techniques such as Machine Learning.
• Ability to work with others as a research team.
• Ability to work in a culturally diverse environment.
