Overview

Organization: National Aeronautics and Space Administration (NASA)

Reference Code: 0048-NPP-NOV26-JPL-EarthSci

Location: Jet Propulsion Laboratory, Pasadena, California

Field of Science: Earth Science

Description

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

This research opportunity is for candidates with special interest in radar remote sensing of vegetation. The proposed project includes radar scattering and ecosystem modeling. The remote sensing data is used to estimate vegetation 3D structure parameters such as height. The radar data (Interferometric Synthetic Aperture Radar or inSAR) was collected by spaceborne ALOS/PALSAR and airborne UAVSAR systems. The candidate will be responsible for processing repeat pass inSAR data and implementing efficient data calibration algorithms based on heterogeneous spatial sampling of ground truth points. These points are extracted from existing Lidar (ICEsat/GLAS) and field data sets. The ecosystem models widely available in the literature will be driven using the derived vegetation parameters.
