Earth’s Future, 2024

• The first application of GEDI in agricultural disaster assessment
• GEDI footprints can well reveal changes in maize height caused by typhoons
• LSWI provides a robust wall-to-wall mapping of crop lodging

European Journal of Agronomy, 2024

• LSWI is the prior indicator for assessing typhoon disturbance in maize
• Week-long lagging impacts of typhoons on maize growth lasted until the end of the growing season
• Spatial-temporal compensation mitigates typhoon impacts on maize in the entire region

Journal of Virology, 2024

• The 2020 outbreak of the H5N8 G1 genotype instead of the G0 genotype produced reassortment opportunities and led to the emergence of a new H5N1 virus with G1’s HA and MP genes
• The spatial-temporal coincidence between the outbreak of the H5N8 G1 virus and the bird autumn migration may have expanded the H5 viral spread
