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

Position Summary:

GST seeks a highly motivated candidate for a position on the JPSS Ozone Mapping and Profiler Suite (OMPS) Sensor Data Record (SDR) team at NOAA/NESDIS/STAR. As a member of the Sensor Data Record (SDR) team, the candidate will develop tools and perform analysis for the calibration and validation for the OMPS Nadir Mapper (NM) and Nadir Profiler (NP). Both sensors are designed to make measurements of the ultraviolet radiance backscattered by the Earth's atmosphere and surface and of the extra-terrestrial solar irradiance. The radiance/irradiance ratios are the principal quantities used in the ozone retrieval algorithms.


Support operational OMPS calibration/validation activities for SNPP and NOAA-20 satellites. Support JPSS-2 OMPS NM/NP pre-launch calibration and post-launch calibration/validation, including but not limited to the following tasks:

1) Impact analysis on SDR data quality due to SNPP/NOAA-20/JPSS2 NM and NP instrument characterization differences;

2) Time dependent radiometric calibration analysis for OMPS SDR data from SNPP/NOAA-20/ JPSS2;

3) Validation of JPSS 2 OMPS SDR data using multiple ways such as the (polarized) radiative transfer modeling and the inter-sensor calibration method; and,

4) Use and Algorithm improvement of the Algorithm Development Library (ADL) OMPS SDR processing code package.

Required Education/Experience/Skills:

  • A Master's degree (Ph.D. preferred) in Atmospheric Sciences, Physics, Remote Sensing, or a related field in Science or Engineering

  • Broad knowledge of physical basis of remote sensing.

  • Experience with satellite data.

Desired Experience/Skills:

  • 3+ years working experience in UV instrument calibration/validation.

  • Experience in UV radiative transfer modeling development.

  • Preferred experience on following programming languages: FORTRAN, C/C++, IDL, Python, Perl in Unix/Linux system.

Physical Qualification(s) Required:

  • Ability to use a computer

Mental Qualification(s) Required:

  • Ability to think on one's feet
