Soil Climate Analysis Network (SCAN)

The Soil Climate Analysis Network (SCAN) was developed to provide near real-time soil-climate information for natural resource planning, drought assessment, and water resource management. Remotely located stations collect atmospheric measurements along with soil moisture and soil temperature. All stations have full soil survey characterization information, as well. This unique network utilizes meteor burst communications technology to provide data in near real-time. Hourly data from this network is quickly made available to the public via the Internet. Currently the network has 111 stations located in 39 states. Most stations have been installed since 1999, following the completion of a 10-year soil moisture/soil temperature pilot project. Station data includes monthly soil moisture, soil temperature, and atmospheric measurements.土壤气候分析网络（Soil Climate Analysis Network，SCAN）专为自然资源规划、干旱评估及水资源管理场景提供近实时的土壤气候信息。部署于偏远区域的观测站点可采集大气观测数据，同步获取土壤湿度与土壤温度数据。所有站点均附带完整的土壤调查特征信息。该独特网络采用流星突发通信技术，能够实现近实时的数据回传。其每小时生成的观测数据可通过互联网快速向公众开放获取。目前该网络在全美39个州共设有111个站点。在一项为期10年的土壤湿度/土壤温度试点项目完成后，多数站点自1999年起陆续建成投用。站点观测数据涵盖月度土壤湿度、土壤温度及大气观测数据。
