Professor Myneni coauthored a paper in PNAS on the dynamics of Amazon Droughts

October 22nd, 2013 in 2013, 2013, Faculty, October-13, Publications, Ranga Myneni

A paper titled “Increased dry-season length over southern Amazonia in recent decades and its implication for future climate projection” by Fu et al. appeared in an early edition of the journal “Proceedings of the National Academy of Sciences of the United States of America” (PNAS) on Tuesday October 21st, 2013. This paper addresses the question of whether the dry-season length will increase as that will determines the fate of the rainforests over Amazonia and future global atmospheric CO2 concentration. The authors show observationally that the dry-season length over southern Amazonia has increased significantly since 1979. Although the causes for this change are unknown, it resembles the effects of anthropogenic climate change. The global climate models that were presented in the Intergovernmental Panel on Climate Change’s fifth assessment report seem to substantially underestimate the variability of the dry-season length. Such a bias implies that the future change of the dry-season length, and hence the risk of rainforest die-back, may be underestimated by the projections of these models.

Alan Strahler joins colleagues in scanning California forests in support of NEON

October 17th, 2013 in 2013, Alan Strahler, Faculty, October-13, Trips

Alan Strahler joined colleagues from UMass Boston, UMass Lowell, and Rochester Institute of Technology in a field terrestrial lidar deployment of the Dual Wavelength Echidna Lidar (DWEL), Canopy Biomass Lidar (CBL), and RIT Terrestrial Lidar (RITTL) to Fresno, California, from June 9-17. where they scanned vegetated sites and made additional vegetation measurements in support of a NEON aircraft campaign. Data were acquired from high- and mid-elevation stands in the Sequoia National Forest as well as shrublands in the foothills near Fresno.

Alan Strahler leads terrestrial lidar scanning field experiment in Brisbane

October 17th, 2013 in 2013, Alan Strahler, Faculty, October-13, Trips

Alan Strahler led group of students and scientists from BU, University of Massachusetts Boston, and University of Massachusetts Lowell, to Brisbane, Queensland, Australia, for a week of terrestrial lidar scanning with the Dual Wavelength Echidna Lidar (DWEL) instrument and UMass Boston’s Canopy Biomass Lidar (CBL) instrument. The event, held from July 28 to August 3, was arranged through a collaboration with the Terrestrial Laser Scanning International Interest Group and co-hosted by the Queensland Department of Science, Information Technology, Innovation, and the Arts and the Commonwealth Scientific and Industrial Research Organization. In addition to the DWEL and CBL, three other instruments scanned the same sites, as part of a plan to intercompare both research and commercial terrestrial laser scanners for a variety of applications in ecology and forestry.
