Julia Barsi has worked on radiometric calibration of Landsat sensors since her senior project at the Rochester Institute of Technology. Upon graduation, she joined the Landsat Calibration Team as a Calibration Analyst and has been working radiometric calibration ever since. She has been involved with radiometric analysis of Landsat-5 TM, Landsat-7 ETM+, EO-1 ALI, Landsat-8 OLI and TIRS and Landsat-9 OLI-2.<\/p>\n

Julia joined the Goddard Laser for Absolute Measurement of Radiance (GLAMR) team as the Science Manager in 2018 and the Calibration Laboratory in 2022, where she helps guide prelaunch spectral and radiometric characterization of a host of instruments including Landsat-9 OLI-2, JPSS VIIRS, CLARREO Pathfinder, and PACE Ocean Color Instrument.
