Minkyu wins outstanding student paper award at fall AGU meeting

February 2nd, 2020 in LCSC, News, Uncategorized

Thrilled to announce that our very own Minyu Moon’s poster presentation at AGU in December was selected as an “outstanding student paper.”  This is a big honor that reflects the exciting new work that Minkyu is working on.  The paper was entitled:  “Climate controls on springtime phenology in Eastern Temperate Forests of North America” and Minkyu is currently in the final stages of writing it up for submission to a journal!

New paper published by PhD student Minkyu Moon

February 2nd, 2020 in LCSC, News, Uncategorized

The second paper from Minkyu's dissertation, which is entitled "Modification of Surface Energy Balance During Springtime: The Relative Importance of Biophysical and Meteorological Changes", has been published in Agricultural and Forest Meteorology.  In this paper, Minkyu uses a novel attribution method based on the first order physics of surface energy balance to explore feedbacks between the atmosphere and surface related to the emergence of leaves during springtime.  A nice mix of ecology and surface climate!

For more information, see the paper, which is now available online from AFM.

New paper published on the sensitivity of global pasturelands to climate change

December 19th, 2019 in LCSC, News

PhD student Radost Stanimirova's new paper entitled "Sensitivity of Global Pasturelands to Climate Variation" was just published in AGU's new transdisciplinary Open Access Journal (Earth's Future).   In this paper, Radost uses  panel-based regression models applied to remote sensing and climate data to characterize  geographic patterns in the sensitivity of global pasturelands to variability and change in the climate system.

Another successful AGU for LCSC in San Francisco

December 19th, 2019 in LCSC, News

Team LCSC had an exciting week of science and socializing at the annual fall meeting of the American Geophysical Union in San Francisco last week.  Altogether, the group presented 8 oral presentations or posters.  We also had an alumni reunion at a local brewery followed by dinner, and spent a day hiking the coastal forests and enjoying the wonders of redwoods in Marin county.  It was a great week :)

New paper on Arctic-Boreal greening and browning published in Environmental Research Letters

December 16th, 2019 in LCSC, News, Uncategorized

The second paper from LCSC alumnus Jon Wang's dissertation has been published in Environmental Research Letters.  This exciting new work builds on previous work in the group by both Jon and Damien Sulla-Menashe, and illustrates the important influence that land cover and land cover change impose on observed greening and browning trends at high latitudes.  Like all things in the natural world, turns out it's complicated!

New LCSC datasets published and available to community

November 3rd, 2019 in LCSC, News, Uncategorized

We have several new datasets that the LCSC team has either developed or contributed to that are now available.  Specifically, new data sets that we generated as part of NASA's ABoVE project have now been published at the Oak Ridge National Lab Distributed Active Archive Center, along with data generated as part of our work with the PhenoCam network, which is funded by the NSF's Macrosystems Biology and NEON-Enabled Science program.

Two new papers published by LCSC Ph.D. Students

October 6th, 2019 in LCSC, News

Big congrats to LCSC team members Radost Stanimirova and Jon Wang, who each published new papers over the last two weeks.  Radost's paper, "An Empirical Assessment of the MODIS Land Cover Dynamics and TIMESAT Land Surface Phenology Algorithms" was published in Remote Sensing. Jon's paper, Extensive land cover change across Arctic–Boreal Northwestern North America from disturbance and climate forcing, was published in Global Change Biology.  Links to both papers can be found on the team publications page.

Dr. Victor Rodriguez-Galiano, visiting scientist.

September 8th, 2019 in LCSC, News

We are happy to welcome Dr. Victor Rodriguez-Galiano from the Department of Physical Geography, Universidad de Sevilla as a visiting scientist to our group during fall, 2019.  Victor is a faculty member at the Universidad de Sevilla with extensive experience in remote sensing, land surface phenology, and machine learning.  He will be collaborating with the team on topics related to our NSF Macrosystems Biology project, and will specifically be examining the use of MODIS data for estimating continental scale "phenoregions" base on MODIS, PhenoCam and climate data.

Welcome Kai-Ting!

As we start the new year, we are excited to welcome Kai-Ting Hu, a new Ph.D. student from Taiwan, into the LCSC family!  Kai-Ting's background is in physical geography and forest ecosystem science, and she is planning to work on topics related to forests, disturbance, and climate change for her dissertation research.  Welcome Kai-Ting - we're thrilled to have you join us.

Summer Meetings and Activities

July 7th, 2019 in News

Summer continues to be a busy time for the LCSC team.  Among other activities, PhD Student Minkyu Moon is currently in Korea, where he is giving 7 (!) invited talks in 3 weeks: Two at Seoul National University, with additional talks at Kangwon National University, Yonsei University, Chungnam National University, the National Institute of Forest Science, and National Institute of Environmental Research.  In addition, Doug Bolton recently represented the LCSC team at the 2019 summer Landsat Science Team meeting at the USGS Earth Resource and Science (EROS) Center in Sioux Falls, where he presented results from our NASA-funded Multisensor Land Imaging Science (MuSLI) project focused on continental-scale phenology from combined Landsat8 and Sentinel 2.  Finally, Leticia Lee is busy supervising two Research Experience for Undergraduates at the Harvard Forest this summer who are collecting data related to leaf spectra, leaf-level photosynthesis, leaf area, and light interception in support of Leticia's dissertation research.
