AimMost of the world's food crops are dependent on pollinators. However, there is a great deal of uncertainty in the strength of this relationship, especially regarding the relative contributions of the honey bee (often a managed species) and wild insects to crop yields on a global scale. Previous data syntheses have likewise reached differing conclusions on whether pollinator species diversity, or

Correcting land surface temperature from thermal imager by considering heterogeneous emissivity Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-04-12 Wenjie Yan, Jiawei Jiang, Lanwu He, Wenli Zhao, Richard Nair, Xu Wang, Yujiu Xiong
It is fundamental to obtain accurate land surface temperature (LST) to study surface energy process. Infrared thermal imagers are commonly used for deriving LST on the basis of radiance measurements. However, when deriving LST from brightness temperature of a blackbody in thermal imagers, thermal imagers only allow setting a fixed land surface emissivity (LSE). This causes uncertainty in retrieving

Using shortest path routing to assess cycling networks J. Transp. Geogr. (IF 5.899) Pub Date : 2024-04-12 Reid Passmore, Kari Watkins, Randall Guensler
The lack of cycling infrastructure is a major deterrent to cycling for transportation in the U.S., yet planners and engineers may lack the tools to assess and communicate the potential network impacts of proposed cycling infrastructure. Without these tools, cycling infrastructure may be built ad hoc or where it is politically convenient, instead of where it would be most effective at improving mobility

MCDNet: Multilevel cloud detection network for remote sensing images based on dual-perspective change-guided and multi-scale feature fusion Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-04-11 Junwu Dong, Yanhui Wang, Yang Yang, Mengqin Yang, Jun Chen
Cloud detection plays a crucial role in the preprocessing of optical remote sensing images. While extensive deep learning-based methods have shown strong performance in detecting thick clouds, their ability to identify thin and broken clouds is often inadequate due to their sparse distribution, semi-transparency, and similarity to background regions. To address this limitation, we introduce a multilevel

Annotating remote sensing images (RSIs) poses a significant challenge, primarily due to its labor-intensive nature. Semi-supervised object detection (SSOD) methods address this challenge by generating pseudo-labels for unlabeled data, assuming that all classes present in the unlabeled dataset are also represented in the labeled data.

As a commonly used indoor internet-of-things (IoT) positioning method, fingerprinting is frequently carried out through the fusion of inertial and WiFi or magnetic data. Nevertheless, signals like magnetic intensity and WiFi received signal strength tend to fluctuate and cannot always provide high accuracy. Thus, other available data can be introduced to maintain positioning continuity and reliability

In recent decades, port efficiency has been widely studied by evaluating the use of the physical factors related to the endowment of infrastructure. However, ports are service providers, so in the production of port cargo services, the time efficiency in port operations matters. In fact, it is a key factor of port competitiveness, especially when shipping lines come to making port choice decisions

Vegetation Condition Index (VCI), as a widely used drought index for monitoring vegetation drought stress and estimating drought trends, is constructed by normalizing the long-term satellite-based Normalized Difference Vegetation Index (NDVI) data. However, under global greening, vegetation across different regions has shown an increasing trend in greenness, which may cause VCI to inherit the greening

Subduction polarity reversal facilitated by plate coupling during arc-continent collision: Evidence from the Western Kunlun orogenic belt, northwest Tibetan Plateau Geology (IF 5.8) Pub Date : 2024-04-01 Zaili Tao, Jiyuan Yin, Christopher J. Spencer, Min Sun, Wenjiao Xiao, Andrew C. Kerr, Tao Wang, Pengpeng Huangfu, Yunchuan Zeng, Wen Chen
Subduction polarity reversal usually involves the break off or tearing of the downgoing plate (DP) along the continent-ocean transition zone, in order to initiate subduction of the overriding plate (OP) with opposite polarity. We propose that subduction polarity reversal can also be caused by DP-OP coupling and can account for the early Paleozoic geological relationships in the Western Kunlun orogenic

The impact of clear-sky biases of land surface temperature on monthly evapotranspiration estimation Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-04-03 Xin Pan, Zhanchuan Wang, Suyi Liu, Zi Yang, Rufat Guluzade, Yuanbo Liu, Jie Yuan, Yingbao Yang
Remotely sensed land surface temperature (LST) is critical for retrieving evapotranspiration (ET). However, due to cloud contamination, LST is often limited to clear-sky conditions and the differences between clear-sky and all-sky LST will lead to clear-sky biases of LST. Consequently, the accuracy of ET varies drastically under different weather conditions. To evaluate the impact of clear-sky biases

The Sturtian “Snowball Earth” glaciation (ca. 717–661 Ma) is regarded as the most extreme interval of icehouse climate in Earth’s history. The exact trigger and sustention mechanisms for this long-lived global glaciation remain obscure. The most widely debated causes are silicate weathering of the ca. 718 Ma Franklin large igneous province (LIP) and changes in the length and degassing of continental

Mantle flow and olivine fabric transition in the Myanmar continental subduction zone Geology (IF 5.8) Pub Date : 2024-04-01 Enbo Fan, Yinshuang Ai, Stephen S. Gao, Yumei He, Kelly H. Liu, Mingming Jiang, Guangbing Hou, Shun Yang, Chit Thet Mon, Myo Thant, Kyaing Sein
One of the major advances in mineral physics and seismology is the realization that different olivine fabric types are functions of temperature, shear stress, and water content in oceanic subducting systems. The distribution of different olivine fabric types and geodynamic processes in the mantle wedge above a subducting continental slab remain poorly understood. Here, based on splitting analysis of
