Glen Jaross has over 30 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 is currently the OMPS Instrument Scientist. 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, launched in late 2017, consists of 2 Nadir sensors. Responsibilities are similar to those of SNPP OMPS.
- JPSS-2 OMPS, launched in late 2022, consists of a complete suite (similar to SNPP). are similar to those of SNPP OMPS.
- JPSS-4, JPSS-3 OMPS, due to launch in 2028 and 2032, respectively, 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 all OMPS. Prepare for future 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.
