The built environment and the frequency of cycling trips by urban elderly : Insights from Zhongshan, China

As a form of active transport, cycling provides significant health benefits to the elderly. Among voluminous active transport-related literature, few studies have investigated the correlates of the cycling activity of urban elderly. This study explored the effects of individual, household, and built environment attributes on the frequency of cycling trips by urban elderly, with data collected from

Hydrologic evaluation of TRMM and GPM IMERG satellite-based precipitation in a humid basin of China

Tropical Rainfall Measurement Mission (TRMM) is one of the most popular global high resolution satellite-based precipitation products with a goal of measuring precipitation over the oceans and tropics. However, in recent years, the TRMM mission has come to an end. Its successor, Global Precipitation Measurement (GPM) mission was launched to measure the earth's precipitation structure, with an aim

Spatial distribution of Diurnal rainfall variation in summer over China

Diurnal rainfall variation plays an important role in the characterization of regional climate. Most existing research used predefined region boundaries to study the spatial differences of diurnal rainfall variation, which depends on experiential knowledge and is somewhat subjective. In this study, the k-means clustering algorithm was used to mine the spatial distribution of diurnal rainfall varia

The rise of China's new energy vehicle lithium-ion battery industry : The coevolution of battery technological innovation systems and policies

In recent decades, the technological innovation systems (TIS) framework has been applied to the study of technology development and diffusion. While policy is considered a key element of TIS analysis, less attention has been paid to the influence of TIS dynamics on policymaking. To better understand the coevolution between TIS and policies, this paper develop an analytical framework to highlight t

Modeling China's terrestrial ecosystem gross primary productivity with BEPS model : Parameter sensitivity analysis and model calibration

Terrestrial ecosystems are the largest sink for carbon, and their ecosystem gross primary productivity (GPP) regulates variations in atmospheric carbon dioxide (CO2) concentrations. Current process-based ecosystem models used for estimating GPP are subject to large uncertainties due to poorly constrained parameter values. In this study, we implemented a global sensitivity analysis (GSA) on paramet

Quaternary rainfall variability is governed by insolation in northern China and ice-sheet forcing in the South

Quaternary Asian low-latitude hydroclimate cyclicity has long been attributed to insolation forcing, in contrast to the dominant ice-sheet and CO2 controls identified in mid-high-latitude regions. However, debates exist regarding these rainfall variations and forcings due to inconsistent reconstructions and simulations. Here, by combining rainfall proxy records with multi-model simulations, domina
