  • Chongya was awarded the “Best Paper Award by Research Institute for Agricultural and Life Sciences in Seoul National University” with his 2016 RSE paper!! Big Congratulations Chongya!!!!
  • Hideki Kobayashi, Kazu Ichii, Yuji Yanagi from JAMSTEC visited us. They are the PI of LAI and GPP/NPP products in the GCOM-C JAXA satellite mission, and decided to use BESS as their global GPP algorithm. We discussed details in BESS. Very excited to see BESS will be embedded in GCOM-C GPP product! They brought their alma mater/current institute symbols (Tokyo Institute of Technology and JAMSTEC).

  • Jongmin has been developing Rotaprism, inspired by Joe Berry. Our system differs from Joe’s one as we use electricity to control rotation of prism. This will be installed in a tall forest SiF system. He is testing and we wish we could control all in Rotaprism.
