    Glen Jaross has over 25 years of experience characterizing, calibrating UV/VIS, satellite sensors used in the retrievals of atmospheric constituents such as ozone, aerosols, and trace gases. His primary interests have been the TOMS and OMPS instruments, for which he leads all phases of pre-launch and post-launch characterization support. He designed much of the sensor data processing algorithm currently used by NASA and NOAA and was a key contributor to the OMPS sensor design, primarily aspects related to in-flight calibration. He also contributed to pre-launch characterization and performance testing of the TOMS, OMI, and OMPS sensors. Specific research interests include sensor inter-calibration, long-term sensor change and characterization over decadal time scales, and validation of sensor calibration. He has developed a technique for assessing the radiometric calibration of remote sensors using radiances measured over Antarctica.

    Current Projects

    OMPS Instrument Scientist

    Currently working on 5 OMPS missions:

    • SNPP OMPS, flying since 2011, is a complete suite consisting of a Limb and 2 Nadir sensors.  Responsible for identifying and resolving operational anomalies.  Data analysis provides lessons-learned for future instrument builds.
    • JPSS-1 OMPS, due to launch in early 2017, consists of 2 Nadir sensors.  Responsibilities include interpreting sensor pre-launch characterizations and other parameters necessary for data processing by NASA and NOAA, and instrument ConOps.  Direct preparations for initial sensor operations including activity definitions and schedules, testing, data analysis, and performance assessments.
    • JPSS-2 OMPS, due to launch in 2021-2022, consists of a complete suite (similar to SNPP).  Responsibilities include incorporating lessons-learned in the design of these sensors and their operation.  Define the scope and content of the characterization program.  Evaluate test data and reported test results.
    • JPSS-3,4 OMPS, due to launch later than 2025, consists of a complete suite.  Current responsibility includes identifying long-lead changes from JPSS-2 OMPS that should be included in requirements and plans.  The goal with these instruments is continuous improvement within the constraints of budget and schedule.

    OMPS Level 1 Products Lead

    This effort involves operating the sensors, maintaining sensor calibration, evaluating the calibration and creating adjustments, and leading the generation of Level 1 products for the SNPP OMPS.  Prepare for JPSS-1 OMPS product generation.  This work requires the coordinated efforts of a large team to effectively conduct data analysis, implement calibrations, monitor performance, and operate of the instrument suite.

    OMPS NOAA Support

    Lead the support to NOAA for Nadir sensor operations and calibration.  Operations of the instrument suite must be coordinated and cannot be effectively conducted by two institutions.  NASA operates the Limb instrument, and operates the Nadir instrument on behalf of NOAA.  The effort also involves providing NASA-generated code and calibrations to NOAA for their use.
