Implementing Dynamic Root Optimization in Noah-MP for Simulating Phreatophytic Root Water Uptake
No full textWidely distributed in arid and semiarid regions, phreatophytic roots extend into the saturated zone and extract water directly from groundwater. In this paper, we implemented a vegetation optimality model of root dynamics (VOM-ROOT) in the Noah land surface model with multiparameterization options (Noah-MP LSM) to model the extraction of groundwater through phreatophytic roots at a riparian site with a hyperarid climate (with precipitation of 35 mm/yr) in northwestern China. VOM-ROOT numerically describes the natural optimization of the root profile in response to changes in subsurface water conditions. The coupled Noah-MP/VOM-ROOT model substantially improves the simulation of surface energy and water fluxes, particularly during the growing season, compared to the prescribed static root profile in the default Noah-MP. In the coupled model, more roots are required to grow into the saturated zone to meet transpiration demand when the groundwater level declines over the growing season. The modeling results indicate that at the study site, the modeled annual transpiration is 472 mm, accounting for 92.3% of the total evapotranspiration. Direct root water uptake from the capillary fringe and groundwater, which is supplied by lateral groundwater flow, accounts for approximately 84% of the total transpiration. This study demonstrates the importance of implementing a dynamic root scheme in a land surface model for adequately simulating phreatophytic root water uptake and the associated latent heat flux.National Natural Science Foundation of China [41671023, 41571029, 41271050]; NSFC-RFBR Program [41811130023, 18-55-53025 GammaPhiEH_a]; China Scholarship Council [201304910063]; NASA MAP Program [80NSSC17K0352]; National Science Foundation for Critical Zone Observatory [NSF-EAR-1331408]; NSF Macrosystem Biology [NSF-EF 1065790]6 month embargo; published online: 20 February 2018This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Samuel Noah Kramer: 10-06-1981
No full textSamuel Noah Kramer was a Sumerian history and language expert and the author of over 25 books and 150 articles on Sumer. He begins the interview by reading a piece of Sumerian literature and continues by discussing what Sumerian literature is about, the time period it was written in, and the types of literature that the Sumerians wrote. He discusses how he got into cuneiform, the system of writing developed by the Sumerians, and talks about coming to the United States as a child. Kramer concludes the interview by discussing how he became an archaeologist.https://digitalcommons.brockport.edu/writers_videos/1020/thumbnail.jp

Under-canopy turbulence and root water uptake of a Tibetan meadow ecosystem modeled by Noah-MP
No full textThe Noah-MP land surface model adopts a multiparameterization framework to accommodate various alternative parameterizations for more than 10 physical processes. In this paper, the parameterizations implemented in Noah-MP associated with under-canopy turbulence and root water uptake are enhanced with: (i) an under-canopy turbulence scheme currently adopted by the Community Land Model (CLM), (ii) two vertical root distribution functions, i.e., an exponential and an asymptotic formulation, and (iii) three soil water stress functions (βt) controlling root water uptake, e.g., a soil water potential (ψ)-based function, a nonlinear soil moisture (θ)-based power function and an empirical threshold approach considering preferential uptake from the moist part of the soil column. A comprehensive data set of in situ micrometeorological observations and profile soil moisture/temperature measurements collected from an alpine meadow site in the northeastern Tibetan Plateau is utilized to assess the impact of the augmentations on the Noah-MP performance. The results indicate that (i) implementation of the CLM under-canopy turbulence scheme greatly resolves the overestimation of sensible heat flux and underestimation of soil temperature across the profile, (ii) both exponential and asymptotic vertical root distribution functions better represent the Tibetan conditions enabling a better representation of the measured soil moisture dynamics, and (iii) the ψ-based βt functions overestimate surface soil moisture, the default linear θ-based βt function underestimates latent heat flux during the dry-down, while both the nonlinear power function and empirical threshold approach simultaneously simulate well soil moisture, and latent and sensible heat fluxes. Additionally, the parameter uncertainty associated with soil water stress function and hydraulic parameterization is addressed
