Airborne Imaging Spectrometer Calibration Scientist
Battelle and its affiliate, Battelle Ecology, Inc. manages and operates the National Ecological Observatory Network (NEON) project, which is solely funded by the National Science Foundation. A 30+ year project dedicated to understanding how changes in climate, land use and invasive species impact ecology, the observatory’s scientists and engineers are collecting a comprehensive range of ecological data on a continental scale across 20 eco-climatic domains representing US ecosystems. Our teams use cutting-edge technology, including an airborne observation platform that captures images of regional landscapes and vegetation; mobile, relocatable, and fixed data collection sites with automated ground sensors to monitor soil and atmosphere; and trained field crews who observe and sample populations of diverse organisms and collect soil and water data. Once structures are completed, a leading-edge cyberinfrastructure will calibrate, store and publish this information. The Observatory includes more than 500+ personnel and is the first of its kind designed to detect and enable forecasting of ecological change at continental scales.
LOCATION: Boulder, CO
The Remote Sensing Team within NEON operates three Airborne Observation Platform (AOP) payloads as an integral part of the observatory infrastructure. Each payload consists of advanced remote sensing instrumentation, including a high-fidelity imaging spectrometer, a waveform-LiDAR and a high-resolution digital camera, in order to provide long-term, quantitative information on land use, vegetation structure and canopy chemistry over the NEON sites locations and other sites of opportunity.
The Remote Sensing Team is currently seeking a calibration scientist who will be responsible for the instrument calibration and data quality assessment of three airborne NEON Imaging Spectrometer (NIS) systems. The position is located in Boulder, CO, and will report to the Remote Sensing Team Lead. The Calibration Scientist will lead the laboratory-based radiometric and spectral calibration, and field-based calibration validation of the NIS systems. This includes quantifying the calibration uncertainty and developing improvements to the calibration equipment and protocols.
The Calibration Scientist will also work closely with the Remote Sensing Science Team to refine procedures for verifying the quality of Level-0 NIS data, develop novel algorithms to support the calibration and production of NIS data products, and assist in routine processing of NIS data products. The successful candidate will produce reports and publications of NEON designs, procedures, and protocols and is highly encouraged to collaborate with NEON staff and the research community in the application of airborne remote sensing to continental-scale ecology. The ideal candidate should have considerable knowledge and experience with the fundamental principles and calibration of airborne and/or spaceborne hyperspectral imaging systems.
