Integration of nitrogen dynamics into the Noah-MP land surface model v1.1 for climate and environmental predictions
Climate and terrestrial biosphere models consider nitrogen an important factor in limiting plant carbon uptake, while operational environmental models view nitrogen as the leading pollutant causing eutrophication in water bodies. The community Noah land surface model with multiparameterization options (Noah-MP) is unique in that it is the next-generation land surface model for the Weather Resea...
متن کاملNitrogen cycling and feedbacks in a global dynamic land model
Global anthropogenic changes in carbon (C) and nitrogen (N) cycles call for modeling tools that are able to address and quantify essential interactions between N, C, and climate in terrestrial ecosystems. Here, we introduce a prognostic N cycle within the Princeton-GFDL LM3V land model. The model captures mechanisms essential for N cycling and their feedbacks on C cycling: N limitation of plant...
متن کاملMechanisms of plant species impacts on ecosystem nitrogen cycling
J. M. H. Knops,* K. L. Bradley and D. A. Wedin School of Biological Sciences, School of Natural Resource Sciences, University of Nebraska, 348 Manter Hall, Lincoln, NE 68588, USA. *Correspondence: E-mail: [email protected] Abstract Plant species are hypothesized to impact ecosystem nitrogen cycling in two distinctly different ways. First, differences in nitrogen use efficiency can lead to positiv...
متن کاملارزیابی مدل برف طرحواره سطح NOAH-MP جفت‌شده با مدل منطقه‌ای WRF در بارش‌های سنگین برف در شمال و غرب ایران
کسر پوشش برف، به دلیل افت‌وخیزهای شدید زمانی و مکانی، ضریب آلبیدوی بالا و رسانایی حرارتی بسیار کم نقش مهمی را در پارامترهسازی برف در طرحوارههای سطح بر عهده دارد. این تحقیق به ارزیابی مدل برف طرحواره سطح NOAH-MP جفت‌شده با مدل WRF با فاکتور ذوب برف پیشفرض مدل میپردازد. منطقه مورد مطالعه نواحی شمالی (استانهای اردبیل، گیلان و مازندران) و غربی ایران (استانهای کردستان و همدان) است که به پنج نا...
متن کاملThe Role of Litter Quality Feedbacks in Terrestrial Nitrogen and Phosphorus Cycling
Many studies in ecosystem ecology argue for strong control of litter quality over nitrogen (N) cycling. We developed a model for temperate grasslands to test the importance of litter quality in decomposition for N and phosphorus (P) cycling based on the following premises. First, terrestrial N and P cycling differ fundamentally because N is a structural component of the soil organic matter (SOM...
