December
Hyungseok joined the lab (master course). Welcome!
Youngryel and Jeehwan attended AGU Fall meeting at San Francisco.
The Ryu group attended The 4th International Winter School and Workshop on Climate/Environment Change at Ewha Womans University (Left). After the Winterschool, Ryu group had a dinner with Professor Jinkyu Hong’s group (Yonsei University) at Shinchon (Right)
The Ryu group had a 2012 farewell party. This was the first beer after lab meeting at SNU.
Jeehwan’s birthday (28 Dec 2012)
November
Andrew’s phenology review paper was published:
Richardson, A.D., Keenan, T.F., Migliavacca, M., Ryu, Y., Sonnentag, O., & Toomey, M. (2013). Climate change, phenology, and phenological control of vegetation feedbacks to the climate system. Agricultural and Forest Meteorology, 169: 156-173
Youngryel visited Biometlab at UC Berkeley and gave a short lab seminar on his current projects. Dennis hosted a nice dinner at his home and Youngryel, Sebastian and Martin joined.
Ryu Lab celebrated the arrival of Li-6400 (photosynthesis/soil respiration measurement). This instrument will play a key role in carbon flux measurements at Seoul Forest Park.
Jeehwan made an amazing progress in digging-up to quantify carbon stock
October
Youngryel appeared in EOS for the recognition of 2011 Editors’ Citation for Excellence in Refereeing for Global Biogeochemical Cycles. See here [PDF]
Youngryel had a short discussion with Rama Nemani (NASA Ames) at San Francisco Airport to run BESS on NASA NEX.
Youngryel attended the Heterotrophic Soil Respiration Workshop hosted by Mark Harmon at HJ Andrews Experimental Forest, Oregon State University.
Group dinner (16 Oct 2012)
September
Camera paper has been published in Remote Sensing of Environment!
Ryu, Y.*, Verfaillie, J., Macfarlane, C., Kobayashi, H., Sonnentag, O., Vargas, R., Ma, S., & Baldocchi, D.D. (2012). Continuous observation of tree leaf area index at ecosystem scale using upward-pointing digital cameras. Remote Sensing of Environment, 126, 116-125 [PDF]
Terrestrial LiDAR survey was conducted in the Seoul Forest Park. The 3D information on canopy structures will be used to quantify carbon stocks, water and carbon fluxes in the park.

Dr. Shin Nagai from JAMSTEC to develop collaborations with PEN-EYE phenology network
Dr. Donggill Kim from Hawassa University in Ethiopia to develop collaborations in installing LED and digital cameras in Ethiopia to monitor vegetation structure and fuctions
April
New grant proposal on quantifying carbon cycle in the Seoul Forest was awarded from Natioanl Research Foundation!! It is 200,000$ over the three years.
Seungjoon was awarded from Volunteer Research Program, CALS, Seoul National University. He will work on the impacts of elevated [CO2] on biophysical properties of leaves. Congratulations!!
The group members worked very hard to calibrate LED sensors against Ocean Optics hyperspectrometer.
Minseok, PhD student at Professor Joon Kim’s lab, joined the NRF Korea-Americas cooperation project.
Six digital cameras with two LED-sensors were installed at two Koflux sites in Gwangneung.
One manuscript on scattering effects on gap fraction estimates was submitted to Agricultural and Forest Meteorology:
Kobayashi, H., Ryu, Y*., Baldocchi, D.D., Welles, J.M., & Norman, J.M. (2012). On the correct estimation of gap fraction: how to remove scattered radiation in the gap fraction measurements? Agricultural and Forest Meteorology, In reivew (* corresponding author)
March
Jeehwan started his master course!
Seungjoon joined the group as a research internship.
Spectral response of LEDs was characterized owing to Professor Jangjoo Kim who runs organic LED research group at SNU.
Youngryel gave a talk at Department of Atmospheric Sciences, Yonsei University. The title was “Integration of near-surface and satellite remote sensing to monitor land-atmosphere interactions from plot to global scales”
