Relationship Between CO2 Flux, Photosynthetically Active Radiation and Meteorological Factors in Evergreen Broad-leaved Forest in the Phoenix Mountain Area of Zhuhai

open access: yesGaoyuan qixiang, 2023
In order to explore the relationship between CO2 flux and photosynthetically active radiation (PAR) in evergreen broad-leaved forest in the Phoenix Mountain, Zhuhai, and improve the ability of simulating CO2 flux by using PAR and meteorological factors ...

An Improved Parameterization for Retrieving Clear-Sky Downward Longwave Radiation from Satellite Thermal Infrared Data

open access: yesRemote Sensing, 2019
Surface downward longwave radiation (DLR) is a crucial component in Earth’s surface energy balance. Yu et al. (2013) developed a parameterization for retrieving clear-sky DLR at high spatial resolution by combined use of satellite thermal infrared (

Adaptive robot climbing with magnetic feet in unknown slippery structure

open access: yesFrontiers in Robotics and AI, 2022
Firm foot contact is the top priority of climbing robots to avoid catastrophic events, especially when working at height. This study proposes a robust planning and control framework for climbing robots that provides robustness to slippage in unknown ...

A Stochastic Framework for Modeling the Population Dynamics of Convective Clouds

open access: yesJournal of Advances in Modeling Earth Systems, 2018
A stochastic prognostic framework for modeling the population dynamics of convective clouds and representing them in climate models is proposed. The framework follows the nonequilibrium statistical mechanical approach to constructing a master equation ...

Multiple‐Instance Superparameterization: 2. The Effects of Stochastic Convection on the Simulated Climate

open access: yesJournal of Advances in Modeling Earth Systems, 2019
The cloud‐permitting model (CPM) of the superparameterized Community Atmosphere Model (SP‐CAM) is a stochastic parameterization. As reported in a companion paper, we have created a variant of SP‐CAM, called MP‐CAM, that uses the averaged feedback of 10 ...

A Parameterization of Local and Remote Tidal Mixing

open access: yesJournal of Advances in Modeling Earth Systems, 2020
Vertical mixing is often regarded as the Achilles' heel of ocean models. In particular, few models include a comprehensive and energy‐constrained parameterization of mixing by internal ocean tides.

A Parameterization of Models for Unit Root Processes: Structure Theory and Hypothesis Testing

open access: yesEconometrics, 2020
We develop and discuss a parameterization of vector autoregressive moving average processes with arbitrary unit roots and (co)integration orders. The detailed analysis of the topological properties of the parameterization—based on the state space ...
