Advanced Science, EarlyView.Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Machine Learning of Temperature‐Dependent Chemical Kinetics Using Parallel Droplet Microreactors
Advanced Science, EarlyView.An integrated droplet microfluidics and machine learning framework enables high‐throughput characterization of temperature‐dependent reaction kinetics. Time‐resolved measurements from thousands of droplets train Neural ODE models that accurately predict nonlinear reaction dynamics across diverse thermal environments, bridging large‐scale ...

Toward unification of the multiscale modeling of the atmosphere [PDF]
Atmospheric Chemistry and Physics, 2011 As far as the representation of deep moist convection is concerned, only two kinds of model physics are used at present: highly parameterized as in the conventional general circulation models (GCMs) and explicitly simulated as in the cloud-resolving ...

Growth of Spread in Convection-Allowing and Convection-Parameterizing Ensembles
Weather and Forecasting, 2010 Abstract During the 2007 NOAA Hazardous Weather Testbed Spring Experiment, a 10-member 4-km grid-spacing Storm-Scale Ensemble Forecast (SSEF) system was run in real time to provide experimental severe weather forecasting guidance. Five SSEF system members used perturbed initial and lateral boundary conditions (ICs and LBCs) and mixed ...

Dependence of MJO Predictability on Convective Parameterizations [PDF]
Journal of Climate, 2020 AbstractThis study revisits MJO predictability based on the “perfect model” approach with a contemporary model. Experiments are performed to address the reasons for substantial uncertainties in current estimates of MJO predictability, with a focus on the influence of atmospheric convection parameterization.

Finite Element Analysis for Li Batteries at the Mesoscale
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...

Importance of convective parameterization in ENSO predictions [PDF]
Geophysical Research Letters, 2017 AbstractThis letter explored the influence of atmospheric convection scheme on El Niño–Southern Oscillation (ENSO) predictions using a set of hindcast experiments. Specifically, a low‐resolution version of the Climate Forecast System version 2 is used for 12 month hindcasts starting from each April during 1982–2011.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A steady‐state numerical model is established for a continuous‐flow pH‐TRC for low‐grade waste heat recovery. Based on carbonate and bicarbonate electrolytes, the influences of operating conditions and electrode structure on pH‐driven power generation are clarified.
