Improving CLM5.0 Biomass and Carbon Exchange across the Western US Using a Data Assimilation System

Biomass enables the transition to a carbon-negative power system across western North America

Sustainable biomass can play a transformative role in the transition to a decarbonized economy, with potential applications in electricity, heat, chemicals and transportation fuels1–3. Deploying bioenergy with carbon capture and sequestration (BECCS) results in a net reduction in atmospheric carbon. BECCS may be one of the few cost-e ective carbon-negative opportunities available should anthrop...

Biomass Burning Observations, Modeling, and Data Assimilation

Carbon Assimilation, Biomass Partitioning and Productivity in Grasses

Plant growth correlates with net carbon gain on a whole plant basis. Over the last several decades, the driving factors shaping plant morphology and performance have become increasingly clear. This review seeks to explore the importance of these factors for grass performance. Briefly, these fall into factors influencing photosynthetic rates directly, competition between plants in a canopy, and ...

a comparative pragmatic analysis of the speech act of “disagreement” across english and persian

the speech act of disagreement has been one of the speech acts that has received the least attention in the field of pragmatics. this study investigates the ways power relations, social distance, formality of the context, gender, and language proficiency (for efl learners) influence disagreement and politeness strategies. the participants of the study were 200 male and female native persian s...

SPECIAL FEATURE: DATA ASSIMILATION Improving the quantification of terrestrial ecosystem carbon dynamics over the United States using an adjoint method

We used an adjoint version of the process-based Terrestrial Ecosystem Model (TEM) to optimize the model parameters in a spatially explicit manner by assimilating satellite-based estimates of gross primary production (GPP) in the conterminous United States. Traditionally, terrestrial ecosystem model parameterization is conducted at site-level for various plant functional types (PFTs). The optima...
