  1. Happy Birtday Prof Ryu-

  1. It was fantastic day (Sep 8). Blue sky, no clouds, comfortable weather. We could not resist on such wonderful weather so went to the stream next to the building. We enjoyed lunch. Seungjun did not bring camera but bring his sunglass. This year seems very dry as stream water was almost dry.

  1. Happy Birthday for Soyoun! Soyoun started the internship in the lab from this month.

  1. We had a farewell party for Prof Song, Wonseok and Jisu, and welcoming party for Dr Huang and Soyoun. Big changes in lab members. Woseok and Jisu successfully completed summer internship program through analyzing spatial and temporal patterns of NDVI in AVHRR over East Asia. Well done, good jobs.



  1. Yan Huang jointed the lab as postdoctoral fellow. Welcome Yan!!

  2. Farewell party for Junhaeng! He has completed two months internship to investigate how climate extreme events influence on the vegetation activity.



  1. Group lunch at BBQ!

  1. Dr Youngkeun Song was offered the faculty position from Graduate School of Environmental Studies, Seoul National University!! We are all excited to this great news. He is the first faculty member from the lab. Big Congratulations Professor Song!! We enjoyed the dinner for Prof Song.

  1. Congratulations Jina and Chongya’s birthdays! Don’t get confused. Seungjun was not the birthday!

  1. Youngryel, Jongmin and Jane enjoyed the field trip to Council, Alaska funded by KOPRI project. A lot of mosquitoes, and fun. We met bears, salmon, and musk ox. We collected many samples of hyperspectral reflectance, LAI, chlorophyll, and light response curves. We intended to measure A-Ci curve but CO2 catridge was not allowed in the passenger airplane. Good lesson to learn which items have to be shipped in advance to the field trip.



  1. Jongmin and Jane were offered the Master Course programs! Congratulations and welcome to join the lab!

  2. Jisu and Wonseok joined the lab as summer internships. Welcome!



  1. The lab had a group dinner to celebrate Sanghee and Junhaeng. Dr Taekyung Yoon joined the dinner.

  1. Junhaeng Ho joined the lab as a research internship. He is undergraduate student at U Nebraska. Welcome and we hope he can learn a series of biometeorological studies in the lab.

  2. Jane Lee joined the lab as a researcher. She is the assistant researcher in the KOPRI and she will take the lead in the Arctic project. Welcome!

  3. Hyungsuk got married on May 16th. Most lab members attended his wedding at Daegu to celebrate his wedding. Congratulations!

  1. Teacher’s day! Thanks for the great gift, the Globe

  1. Eddy covariance and SiF (Sun induced chlorophyll fluorescence) system have been installed in a rice paddy site at Cheolwon. This is the teamwork with NCAM to monitor rice situations funded by Korea Meteorological Administration.

  1. Dan Fay, Director of Earth and Environment in Microsoft Research, visited the lab to discuss our current research and Azure.

  1. Youngkeun’s manuscript has been accepted for publication in Ecological Research. Congratulations!

  4. Dr Kazu Ichii visited the lab and discussed about carbon cycle research in East Asia


  1. Birthday! Apparently, Jina and Seungjun’s birthday, but actually, Hyungsuk’s birthday 🙂 We needed 29 candles.

  1. Youngryel attended Titta Majasalmi’s PhD defence at University of Helsinki. Youngryel was the pre-examiner in her thesis. Other pre-examiner was Inge Jonckheere, and the opponent of her thesis was Sari Palmroth. Titta’s two advisers, Drs Pauline Stenberg and Miina Rautianien, hosted Youngryel. In Helsinki, Youngryel finally met Dr Tiit Nilson (Tartu Obervatory, Estonia) who contributed two LAI papers in 2010. Also, Youngryel gave the Departmental seminar at U Helsinki on the monitoring of multi-layer canopy phenology in Gwangneung forest.


Lunch with Tiit Nilson, Pauline Stenberg, and Miina Rautiainen.


Dinner party after Titta’s defence. Very formal- dress code was black coat.
