Climatic influences on changing landcover, water availability and biomass production are components of a dynamic Earth System that can be monitored with satellite earth observation (EO) data. EO land and water monitoring and regional climate modeling are becoming commonplace tools to support government resource, hazard and environmental assessments, and for land/water use and Carbon emissions policy. The increasing reliance on EO data to understand, manage and plan societal interaction with the Environment has resulted in many recent or imminent satellite launches with goals of monitoring global biomass to water extent and levels. A challenge with satellite EO data is converting images into meaningful representations of ground level feature properties and then relating image-based changes to ecosystem processes. My Dynamic Ecosystem Landcover Transitions Assessment (DELTA) program uses multi-scale EO data to examine forest and wetland ecosystem response to perturbations in the climate system along elevation and latitude gradients.

气候对不断变化的土地覆盖、水的供应和生物量生产的影响是动态地球系统的组成部分，可以用卫星地球观测数据进行监测。EO土地和水监测以及区域气候建模正在成为支持政府资源、灾害和环境评估以及土地/水利用和碳排放政策的常用工具。越来越多地依赖EO数据来理解，管理和规划与环境的社会互动，导致最近或即将发射许多卫星，其目标是监测全球生物量到水的范围和水平。卫星地球观测数据的一个挑战是将图像转换成地面特征特性的有意义的表示，然后将基于图像的变化与生态系统过程联系起来。我的动态生态系统土地覆盖过渡评估（DELTA）计划使用多尺度EO数据来检查森林和湿地生态系统对气候系统沿着海拔和纬度梯度扰动的响应。
