The three dimensional structure of vegetation and changes in this structure resulting from either natural or anthropogenic causes are key parameters in understanding and monitoring ecosystems. SAR tomographic methods has proven extremely adept at measuring vegetation vertical structure at a variety of wavelengths including L and P-bands. The NASA/JPL UAVSAR system has deployed to Germany, Alaska and Gabon over the last several years to conduct tomographic SAR observations at L-band and P-band. This talk will provide a brief overview of a tomographic SAR experiment conducted in the boreal forests of Alaska in August and September of 2017 at both L and P-bands. Vegetation at this site is relatively short with mean height less than 20 m and maximal height less than 25 m. Vegetation is sparse compared with previous temperate and tropical forest tomographic observations made by UAVSAR. These observations provides a unique data set to compare tomographic data at L and P-bands for this type of ecosystem.
