블로그 시작과 플랫폼 선택

📅 Dec 8, 2019 · ☕ 2 min read · ✍️ HoonTaek Lee

블로그를 시작한다. 서평, 논문 리뷰, 생각 등 남겨두고 싶은 것들을 그냥 흘려보내지 않기 위함이 첫째다. 그리고 기록을 함으로써 생각을 구체적으로 정리할 수 있을 것

Paper Review: Bar (2019). Fire. NPH

📅 Dec 7, 2019 · ☕ 1 min read · ✍️ Hoontaek Lee

7 December, 2019 (Bar, NPH, Fire) Bär, A., Michaletz, S.T. and Mayr, S. (2019), Fire effects on tree physiology. New Phytologist, 223: 1728-1741. doi:10.1111/nph.15871 My research group at NIFOS was invited to write a research paper for a special issue of a journal. We decided to write a paper about the lagged browning after the forest fire at April 2019. I wrote about how forest fire affects an individual tree’s physiology, referring majorly to this paper.

Intro 이 책은 좋은 국내 과학 저서를 여러 권 소개해준다는 점에서 가치 있다. 또한 글 쓸 때 고려해볼만한 기본적이면서도 유용한 지침들도 함께 담겨있다. 그냥 지나칠 수 없는

신이 내린 필력은 없지만 잘 쓰고 싶습니다

Intro 나는 여러 권의 글쓰기 관련 책을 읽었다. 그 중 한 권을 추천한다면 영문 도서는 Joshua Schimel의 “Writing Science”를, 한글 도서는 이 책을 추천

Paper Review: Resco de Dios (2019). FMC. AFM

📅 Aug 12, 2019 · ☕ 1 min read · ✍️ Hoontaek Lee

12 August, 2019 (Resco de Dios, AFM, FMC) Resco de Dios, V., Fellows, A.W., Nolan, R.H., Boer, M.M., Bradstock, R.A., Domingo, F. and Goulden, M.L. (2015). A semi-mechanistic model for predicting the moisture content of fine litter. Agricultural and Forest Meteorology, 203, 64-73. I read this paper to get some hints for my fuel moisture research at NIFOS. This paper developed a semi-mechanistic model in which fuel moisture content (FMC) and vapor pressure deficit (VPD) were exponentially related.

Paper Review: Vinodkumar (2019). SMC. AFM

📅 Jun 22, 2019 · ☕ 2 min read · ✍️ Hoontaek Lee

22 June, 2019 (Vinodkumar, AFM, SMC) Vinodkumar and Dharssi (2019). Evaluation and calibration of a high-resolution soil moisture product for wildfire prediction and management. Agricultural and Forest Meteorology, 264, 27-39. This paper can be a good guide for both of my researches at SNU and NIFOS. This paper used the JULES to predict soil moisture deficit (SMD), which is similar to the object of the study at SNU. On the other hand, the purpose of SMD prediction was to imporve a fire danger index, which is the same as my research at NIFOS.

Paper Review: Berry (2019). FWU. PCE

15 June, 2019 (Berry, pce, FWU) Berry, Z.C., Emery, N.C., Gotsch, S.G., Goldsmith, G.R. (2019). Foliar water uptake: Processes, pathways, and integration into plant water budgets. Plant, Cell and Environment, 42, 410-423. As I saw foliar water uptake (FWU) in alert lists sometimes, I became curious about the process. So I read this paper. FWU was observed about 400 years ago (1727), but it seems like relatively new and immatured field.

Paper Review: Hartmann (2018). Mortality. NPH

📅 Jun 8, 2019 · ☕ 1 min read · ✍️ Hoontaek Lee

8 June, 2019 (Hartmann, NPH, Mortality) Hartmann, H., Moura, C.F., Anderegg, W.R.L., Ruehr, N.K., Salmon, Y., Allen, C.D., Arndt, S.K., Breshears, D.D., Davi, H. and Galbraith, D. (2018). Research frontiers for improving our understanding of drought-induced tree and forest mortality. New Phytologist, 218(1), 15-28. This paper suggests some research frontiers (questions) about plant responses to drought. But, rather than the suggestions, I was interested in the topic of Box 1: definition of death for plants.

Paper Review: Li (2018). SIF. GCB

📅 May 26, 2019 · ☕ 2 min read · ✍️ Hoontaek Lee

26 May, 2019 (Li, GCB, SIF) Li, X., Xiao, J., He, B., Altaf Arain, M., Beringer, J., Desai, A.R., Emmel, C., Hollinger, D.Y., Krasnova, A., Mammarella, I., Noe, S.M., Ortiz, P.S., Rey-Sanchez, A.C., Rocha, A.V. and Varlagin, A. (2018). Solar-induced chlorophyll fluorescence is strongly correlated with terrestrial photosynthesis for a wide variety of biomes: First global analysis based on OCO-2 and flux tower observations. Global Change Biology, 24(9), 3990-4008. This paper demonstrates that SIF is a strong proxy of terrestrial GPP using different point of view.

Paper Review: Fisher (2014). TBM. ANN

📅 May 18, 2019 · ☕ 1 min read · ✍️ Hoontaek Lee

18 May, 2019 (Fisher, ANN, TBM) Fisher, J.B., Huntzinger, D.N., Schwalm, C.R. and Sitch, S. (2014). Modeling the terrestrial biosphere. Annual Review of Environment and Resources, 39, 91-123. This paper synthesized in what context the terrestrial biosphere model (TBM) appeared, which processes TBMs included, and what’s next. It was interesting that actually many part of the TBM was studied and developed separately around the world, and the development was accelerated after the parts were incorporated into a type of model.

Paper Review: Zhang (2019). CLM4.5. JGRBG

📅 May 11, 2019 · ☕ 2 min read · ✍️ Hoontaek Lee

11 May, 2019 (Zhang, JGRBG, CLM4.5) Zhang, L., Lei, H., Shen, H., Cong, Z., Yang, D. and Liu, T. (2019). Evaluating the representation of vegetation phenology in the Community Land model 4.5 in a temperate grassland. Journal of Geophysical Research: Biogeosciences 124. This was a key paper for the first revision of my paper. This paper had its focus on improving phenology module in CLM 4.5 by comparing MODIS LAI. Two problem were issued and resolved.

Paper Review: Xu (2016). ED-Hydro. NPH

📅 May 5, 2019 · ☕ 2 min read · ✍️ Hoontaek Lee

5 May, 2019 (Xu, NPH, ED-Hydro) Xu, X., Medvigy, D., Powers, J.S., Becknell, J.M. and Guan, K. (2016). Diversity in plant hydraulic traits explains seasonal and inter‐annual variations of vegetation dynamics in seasonally dry tropical forests. New Phytologist 212(1), 80-95. This paper incoporated hydraulic module into the ED2. This module accounted for hydraulic traits such as tugor loss point (TLP), saturated xylem conductivity, 50% xylem conductivity loss water potential, and area-based A~net~ under sufficient water supply.
