Within vascular plants, the partitioning of hydraulic resistance along the soil-to-leaf continuum affects transpiration and its response to environmental conditions. In trees, the fractional contribut...
对流层大气位涡的源汇位于地表。2023年来，越来越多的研究发现地表位涡强迫对大气环流异常的重要贡献。之前，国际上关于地表位涡强迫的研究多聚焦在阿尔卑斯山地区，中国科学院大气物理研究所LASG实验室吴国雄院士团队经过多年的研究指出青藏高原是大气位涡的重要源汇区，其地表位涡强迫对东亚地区冬季和夏季的极端天气过程均具有重要影响(Wu et al., 2020; He et al., 2022; Ma e...
High in the atmosphere of Venus, a swirl of sulfur-containing clouds blankets the planet. Dark spots in these clouds correspond with areas of high ultraviolet light absorption, but researchers have ye...
双碳战略中温室气体收支的精准测量和核算方面仍然蕴含诸多关键科学问题函待解决，需要高时频、高分辨的有效观测数据予以支撑。无人机由于其成本低、机动性高、悬停稳定等特点，有潜力成为温室气体天空地一体化观测中重要的组成部分。微小型无人机平台技术较新，国内外基于此类无人机探测的研究处于起步阶段，还未形成成熟的观测标准。
