Global Science &Technology, Inc. (GST), a fast-growing high technology firm is seeking mid to senior scientists for an exciting task at the Satellite Oceanography and Climatology Division at NOAA's Center for Satellite Technology Applications and Research (STAR). This task involves broad research and application activities for ocean color remote sensing including algorithm development, testing, evaluation, and validation. Selected candidates shall work with the project leader and other members in STAR and other NOAA offices for some (or all) of the specific tasks provided below.


  • Sensor on-orbit calibration using solar and lunar approaches, in particular, for all VIIRS routine on-orbit calibrations (i.e., VIIRS on the SNPP and NOAA-20 satellites, as well as futures VIIRS on the JPSS series).
  • Analyze the simulated and satellite data, as well as various in situ data from ocean color and atmosphere to evaluate and improve related algorithm performance.
  • Review ocean color related documentations to study and understand ocean color remote sensing theory, algorithm, and applications; an understanding of instrument calibration is highly desirable.
  • Development and applications of satellite algorithms for water properties, e.g., algorithms for biological and biogeochemical properties, IOPs, PFT, etc.
  • Become familiar and work with the ocean color data processing system for research and algorithm development, e.g., SeaDAS, MSL12, ADL, for the data processing, data displaying, and data analyses for various satellite data sets (e.g., VIIRS, MODIS, OLCI on Sentinel-3, SGLI on GCOM-C, etc.).
  • Work with other non-ocean color satellite sensor data (for atmosphere and land purposes), e.g., CALIPSO data, for developing and testing new approaches for remote sensing of ocean properties.
  • Support the identification and resolution of shortfalls in existing open ocean algorithms for application to coastal regions and identification of new applications and products from satellite measurements specifically for coastal and inland water applications.
  • Contribute documentation related to the project.

Required Education/Experience/Skills:

  • Ph.D. in Oceanography, Physics, Computer Science, and/or other Physical Sciences and Engineering¬†and a minimum of 5 years of professional experience. Equivalent experience as well as recent graduate degrees with an exceptional background will be considered.
  • Strong working knowledge of remote sensing algorithms. Understanding of satellite instrument calibration will be a plus.
  • Experience with one or more computer programming languages, such as IDL, Python, Matlab, FORTRAN, and C/C++.
  • Good working knowledge of the Linux/Unix OS
  • A very strong candidate without some of the above qualifications will be considered.

Physical Qualification(s) Required:

  • Ability to use a computer.

Mental Qualification(s) Required:

  • Ability to think on one's feet.

U.S. citizenship or Permanent Resident (Green Card holder) is required.


This employee will have a strong ability to work on tasks independently and collaboratively. A strong team player is required to work tightly knit SOCD teams. Travel to select subject-matter oriented conferences may be required of the successful candidate.

GST offers competitive salaries; vacation, sick, and holiday leave; major medical, dental, life, long-term and short-term disability insurance; 401K retirement plan; tuition assistance; and opportunities for employee career growth and development.

If you need assistance, please call 301-474-9696.All qualified applicants will receive consideration for employment without regard to age, race, color, religion, sex, sexual orientation, gender identity, national origin, disability, veterans' status.  GST is an Equal Opportunity/Affirmative Action Employer.
