Soil moisture is a critical land surface variable, affecting a wide variety of climatological, agricultural, and hydrological processes. Determining the current soil moisture status is possible via a variety of methods, including in situ monitoring, remote sensing, and numerical modeling. Although all of these approaches are rapidly evolving, there is no cohesive strategy or framework to integrate these diverse information sources to develop and disseminate coordinated national soil moisture products that will improve our ability to understand climate variability. The National Coordinated Soil Moisture Monitoring Network initiative has developed a national strategy for network coordination with NOAA's National Integrated Drought Information System. The strategy is currently in review within NOAA, and work is underway to implement the initial milestones of the strategy. This update reviews the goals and steps being taken to establish this national-scale coordination for soil moisture monitoring in the United States.

制定国家协调土壤水分监测网络战略

土壤水分是一个关键的地表变量，影响着各种气候、农业和水文过程。可以通过多种方法确定当前的土壤水分状况，包括原位监测、遥感和数值建模。尽管所有这些方法都在迅速发展，但没有统一的战略或框架来整合这些不同的信息来源，以开发和传播协调的国家土壤水分产品，以提高我们了解气候变异的能力。国家协调土壤水分监测网络倡议制定了与 NOAA 的国家综合干旱信息系统进行网络协调的国家战略。该战略目前正在 NOAA 内部进行审查，并且正在努力实施该战略的最初里程碑。本更新回顾了为在美国建立土壤水分监测的国家级协调而采取的目标和步骤。
