Satellite_Observed Changes in Forest Cover over Northern China from 1996_2020
<p>This dataset is associated with a research article entitled "Satellite_Observed Changes in Forest Cover over Northern China from 1996_2020".</p> <p>As an important part of the land surface, forest is an important factor affecting global carbon, water cycle and climate change; Fractional Forest Cover (FFC) represents the proportion of forest canopy cover area to the whole pixel observed from the vertical direction. It is an important parameter for monitoring forest resources and is related to forest structure or attributes, such as forest area or forest distribution density. It is a variable representing forest cover on a continuous scale.</p> <p>Based on the remote sensing images of Gaofen-2 and Landsat-8, a model for estimating the FFC in the three-north regions of China is constructed based on the ensemble machine learning method. From 1996 to 2020, the annual FFC products with a resolution of 30 meters covering the three northern regions of China with long time series have been generated. The data values contained in the FFC range from 0 to 100, the "Nodata" value is set to -99, and the data file is provided in Geo-Tiff format.</p>
Effect of Vertical Shear in the Zonal Wind on Equatorial Electrojet Sidebands: An Observational Perspective Using Swarm and ICON Data
<p>This data set consists of outputs from the EEJ model by Richmond (1973). The data provided is used in the manuscript titled 'Effect of Vertical Shear in the Zonal Wind on Equatorial Electrojet Sidebands: An Observational Perspective Using Swarm and ICON Data' by J. Sreelakshmi et al.</p> <p>Abstract of the manuscript:</p> <p>The wind dynamo in the ionosphere leads to differential motion of ions and electrons, which in turn sets up electric fields and currents. Observations show that daytime lower thermospheric horizontal winds have large vertical gradients. Numerical modelling conducted approximately 50 years ago demonstrated that the zonal wind shears in the ~130-180km altitude range can generate off-equatorial relative minima (dips) in the daytime height-integrated eastward current density, appearing as westward sidebands north and south of the equatorial electrojet (EEJ). This study observationally confirms this connection for the first time by combining Ionospheric CONnection explorer zonal wind profiles and Swarm latitudinal zonal currents. We demonstrate observationally that the magnitude of the EEJ sideband current is proportional to the strength of westward turning winds with altitude in the Pedersen conductivity dominated region. Additional numerical experiments explain the importance of wind shear in different altitude regions in generating the sideband current. This study contributes to the better understanding of the neutral wind effect on local current generation.</p>

Figs 7, 8 in Field observations on Milichia patrizii ant-mugging flies (Diptera: Milichiidae: Milichiinae) in KwaZulu-Natal, South Africa
Figs 7, 8. (7) Food exchange ends when the fly retracts its mouthparts. The ant briefly sits motionless following the interaction; (8) Trophallaxis food-sharing behaviour between two Crematogaster castanea tricolor nestmates.
