Environmental Awareness and Happiness [PDF]

open access: yes, 2005
The focus of this paper is on the relationship between an individual's environmental attitudes (or awareness) and well-being. We use an ordered probit model to examine the relationship between individual measures of subjective well-being and environmental attitudes regarding ozone pollution and species extinction.

Analysis of the correlation between horizontal wind and 11-year solar activity over Langfang, China

open access: yesEarth and Planetary Physics, 2021
In this study, long term observations of medium frequency (MF) radar at Langfang site (39.4°N, 116.7°E) from 2009 to 2020 have been used to analyze the dependence of the 11-year solar cycle on horizontal winds in the local mesosphere and lower ...

Atmospheric Gravity Wave Potential Energy Observed by Rayleigh Lidar above Jiuquan (40° N, 95° E), China

open access: yesAtmosphere, 2022
Two years of observational data from the 532 nm Rayleigh lidar were used to study the vertical profile characteristics of atmospheric gravity wave potential energy density (GWPED) between 40–80 km above Jiuquan (40° N, 95° E) for the first time.

Impacts of CMEs on Earth Based on Logistic Regression and Recommendation Algorithm

open access: yesSpace: Science & Technology, 2022
Coronal mass ejections (CMEs) are one of the major disturbance sources of space weather. Therefore, it is of great significance to determine whether CMEs will reach the earth.

Energy-Based Adversarial Example Detection for SAR Images

open access: yesRemote Sensing, 2022
Adversarial examples (AEs) bring increasing concern on the security of deep-learning-based synthetic aperture radar (SAR) target recognition systems. SAR AEs with perturbation constrained to the vicinity of the target have been recently in the spotlight ...

A selective up-sampling method applied upon unbalanced data for flare prediction: potential to improve model performance

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The Spaceweather HMI Active Region Patch (SHARP) parameters have been widely used to develop flare prediction models. The relatively small number of strong-flare events leads to an unbalanced dataset that prediction models can be sensitive to the ...

Initial Results of Meteor Wind with Langfang Medium Frequency Radar

open access: yesAtmosphere, 2020
We conducted meteor observations during the Leonid meteor shower on 16 November 2017 and 17 November 2018 with Langfang medium frequency (MF) radar (116° E, 40° N). This was the first nighttime meteor observation by MF radar in mid-latitude China.
