Combining tower mixing ratio and community model data to estimate regional-scale net ecosystem carbon exchange by boundary layer inversion over 4 flux towers in the U.S.A. [PDF]
, 2011 We evaluated an idealized boundary layer (BL) model with simple parameterizations using vertical transport information from community model outputs (NCAR/NCEP Reanalysis and ECMWF Interim Analysis) to estimate regional-scale net CO2 fluxes from 2002 to ...

Land surface model performance using cosmic-ray and point-scale soil moisture measurements for calibration [PDF]
Hydrology and Earth System Sciences, 2017 At very high resolution scale (i.e. grid cells of 1 km2), land surface model parameters can be calibrated with eddy-covariance flux data and point-scale soil moisture data.

Fluid flow dynamics under location uncertainty [PDF]
, 2013 We present a derivation of a stochastic model of Navier Stokes equations that relies on a decomposition of the velocity fields into a differentiable drift component and a time uncorrelated uncertainty random term.

JCPP Advances, EarlyView.This paper details the protocol for the My Emotions and Me Over Time (MEMO) study, a longitudinal study exploring why ADHD and/or autism traits place adolescents at greater risk for depression. This study will explore two potential mediating factors in pathways to depression: emotional regulation deficits; and emotional burden.

Towards a consistent eddy-covariance processing: an intercomparison of EddyPro and TK3 [PDF]
Atmospheric Measurement Techniques, 2014 A comparison of two popular eddy-covariance software packages is presented, namely, EddyPro and TK3. Two approximately 1-month long test data sets were processed, representing typical instrumental setups (i.e., CSAT3/LI-7500 above grassland and Solent R3/

Land Degradation &Development, EarlyView.ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.

Eddy Covariance: A Scientometric Review (1981-2018)
, 2022 The history of eddy covariance (EC) measuring system could be dated back to 100 years ago, but it was not until the recent decades that EC gains popularity and being widely used in global change ecological studies, with explosion of related work published in papers from various journals.
