2018

July

  • Our paddy rice SiF manuscript has been accepted for publication in Remote Sensing of Environment!!!! This is the outcome from a remarkable collaborations with multiple groups.

Yang, K.Ryu, Y.*Dechant, B., Berry, J.A., Hwang, Y.Jiang, C., Kang, M., Kim, J.Kimm, H., Kornfeld, A., & Yang, X. (2018). Sun-induced chlorophyll fluorescence is more strongly related to absorbed light than to photosynthesis at half-hourly resolution in a rice paddy. Remote Sensing of Environment, In press

June

  • The joint workshop proposal with Yongguang Zhang at Nanjing Univ has been funded by NRF. We will organize one week SiF workshop between two groups with other people in Oct. It will be an important and exciting workshop!
  • Congratulations Yunah’s birthday!

  • Youngryel attended AOGS meeting in Hawaii and gave a talk on the coupled remote sensing of global radiation/energy/carbon fluxes. He met Kazu, Wei, Xiaolin, Forrest, Trevor, Haemi, etc etc.
  • Jongmin visited U Motreal hosted by Oliver Sonnentag. He stayed one month and installed our low-cost in-situ SiF sensor in Mer Bleue and Scotty Creek sites. He also gave a talk for his sensor in an annual meeting of Mer Bleue site. He met Taifeng Dong of Agriculture and Agri-Food Canada in Mer Bleue site.

  • In our paddy rice site, we manually planted rice near the flux tower, but it turned out that they did not grow as much as surrounding canopy because of the lack of fertilizer. The farmer added the fertilizer near the tower again. See the spatial heterogeneity in the canopy, and this highlights the necessity in measuring bi-hemispheric reflectance to cover larger footprint. Typically, vegetation density around the tower is low because of safety issue.

May

  • Kaige gave a finishing talk for her master thesis. She is going to start a new job in the blockchain company in Shenzen from this summer. Congratulations and our best wishes for your next career!

  • Juwon and Yan have been collecting spectral reflectance across the rice paddy landscape to evaluate image fusion products.

  • Jongmin is developing a low cost SiF system by combining Raspberry, Arduino, photodiode, and very narrow band pass filter.

April

  • Rice transplantation was done. As the farmer didn’t transplant around the flux tower, our lab folks manually transplanted!

  • Yorum and Jongmin got married! Big congratulations and this is the first couple-to-marriage in the lab history!

 

March

  • Ben and Jongmin visit Cherwon rice paddy site. Homogeneous now, but it will be soon very heterogeneous with different timings in irrigation and transplantation across the landscape.resize_kakaotalk_20180323_092446255
  • Graham Farquhar visited Carnegie institute. Youngryel discussed with Graham about two-leaf model structure and kinetic parameters in Rusbisco. He gave a lecture on history of his modeling works. Below photo includes his metal for Kyoto Prize.

  • Yan’s BESS-Rice has been accepted for publication in Agricultural and Forest Meteorology! This is the first paper from Cherwon flux tower site where our group has been investing extraordinary efforts. Very exciting and big congratulations to Yan-
  • Jongmin’s 4S manuscript has been submitted to Agricultural and Forest Meteorology. Fingers crossed!
  • Ben established our lab web page in ResearchGate. Visit HERE 

February

  • Jane and Soyoun graduated and they earned the master degree! Big congratulations!! Soyoun will work at Research Institute for Agriculture and Life Sciences at SNU, and Jane will return to Zimbabwe to have some break to start the next career.

  • Youngryel was invited to join Editorial Board Member in Remote Sensing, and accepted. Wish to contribute to remote sensing community through both journals, Remote Sensing of Environment (Associate Editor) and Remote Sensing.
  • Kaige’s SiF manuscript has been submitted to RSE. This is the product from collective efforts across multiple groups over multiple years.
  • Trevor Keenan, Josh Fisher, Remi Luo visited Carnegie and we had a project meeting with Anna and Joe. Towards a better global photosynthesis estimate!
  • Youngryel attended Berkeley Atmospheric Science Center (BASC) sympoisum held at Berkeley. He joined the beer with Trevor’s folks– first met Remi and Cecilia.
  • Lab members had a farewell party for Soyoun and Jane who will earn Master degree this Feb, and for Jung-Eun who conducted internship over two consecutive breaks in summer and winter.

January

  • Steve Running visited Carnegie and Berry lab group had discussion about global RS and photosynthesis with him.
  • Kaige visits UIUC for SiF collaboration with Kaiyu Guan’s group. Yelu Zeng from Carnegie Institution for Science also joins this meeting. We are going to combine three in-situ SiF datasets with Yelu’s SiF canopy RT model.
