Science Systems and Applications Inc. (SSAI) is seeking a Scientific Analyst to support Landsat Calibration and Validation Team as well as instrumentation, data collection and laboratory support for the Biospheric Sciences Laboratory (Code 618).
The successful applicant will support will support the Landsat Calibration and Validation Team in mission sensor characterization and calibrations activities. Responsibilities include:Calibrating on-orbit detector response across NIR, SWIR and TIR bands, to internal calibration systems, and solar calibrators (as applicable) and comparing and integrating results with those generated by vicarious calibration system activitiesDocumenting changes to the pre-launch and post-launch performance and characteristicsGenerating and testing Landsat instrument calibration parameter updates to maintain and improve data productsDeveloping and/or revise, prototype and verify the implementation of algorithms for the characterization of Landsat instrument, radiometric, spatial, and geometric performance, as needed based on on-orbit performanceEvaluating the radiometric or geometric properties of non-NASA and non-USGS land imaging sensors and and performing comparisons/cross calibrations with the Landsat sensorsParticipating in Landsat Project Science staff meetings, Landsat Project Management staff meetings, Organizing and participating in Landsat working groupsSupporting the development and refinement of future Landsat instrument and system performance requirementsAdditionally, this role will provide the Biospheric Sciences Laboratory with instrumentation support, data collection and laboratory support, including but not limited to instruments such as ASD FR spectrometers, Landsat Transfer Radiometers (LXR),
Ocean Optics spectrometer, IRT instruments and blackbody calibration. Landsat Calibration and Validation Team support will also include mission sensor characterization and calibrations activities.
Responsibilities include:Conduct calibrations every six months for the ASD FR units and annually for the LXR, IRTocean optics spectrometer and black body calibration sourceProvide instrument support for the listed instruments during field experiments through preparation, transport or shipping, and set-up of equipment in the field; and perform trouble-shooting diagnostics on the instruments during experimentsCollect and provide data assessments in support of field and laboratory projectsDevelop and use computer programs to acquire and calibrate data from laboratory and field spectrometers and radiometersSchedule the use of instruments and maintain a log of their usageKeep track of and maintain the laboratory and field equipment used by Code 618, including inventorying, storing and excessing equipmentAssist with field experiment operations, instrumentation upgrades and upkeep, and field measurements in support of the collaborative research led by Code 618 scientists such as at USDA Beltsville Agricultural Research Center, NIST, or other remote sitesRequired Qualifications:MS degree in engineering or any of the physical sciences, with familiarity or experience with lab instrument characterization and calibration techniquesProgramming skills: MATLAB, IDL, Sql/Perl, Python, C/C++ Familiarity with various scientific dataset formats e.g., HDF4/5 Must work well within a team environment EOE, including disability/vets
