Abstract ATM-9809460 Schwartz, Mark University of Wisconsin Title: Connecting Spring Phenology with Lower Atmospheric Energy-Mass Exchange The objectives of the proposed research are to gain further understanding of the progression and intra-annual variability of the first appearance of spring foliage--the green wave-within North American biomes and selected other mid-latitude regions; and to develop a prototype technique (utilizing new high temporal resolution remote sensing data in concert with surface phenological data and models) to monitor annual and long-term variability of the mid-latitude green wave. The work is important because it will enhance theoretical understanding of the atmosphere and biosphere by integrating data on a variety of spatial scales (global to local) thereby clarifying the relative importance of different physical processes for modeling at all scales.

摘要ATM-9809460 Schwartz，Mark威斯康星州大学标题：连接春季物候与低层大气能量-质量交换 拟议研究的目的是进一步了解北美生物群落和其他中纬度地区春季树叶首次出现-绿色波-的进展和年内变化;并开发出一种原型技术（利用新的高时间分辨率遥感数据与表面物候数据和模型相结合）来监测年度和长期中纬度绿色波的项变率。这项工作很重要，因为它将通过整合各种空间尺度（全球到地方）的数据，从而澄清不同物理过程对所有尺度建模的相对重要性，从而加强对大气和生物圈的理论理解。
