USA National Phenology Network Observational Data Documentation

The goals of the USA National Phenology Network (USA-NPN) are to advance science, inform decisions, and communicate and connect with the public regarding phenology and species’ responses to environmental variation and climate change. The USA-NPN seeks to advance the science of phenology and facilitate ecosystem stewardship by providing phenological information freely and openly. To accomplish these goals, the USA-NPN National Coordinating Office (NCO) delivers observational data on plant and animal phenology in several formats, including minimally processed status and intensity datasets and derived phenometrics for individual plants, sites, and regions. This document describes the suite of observational data products delivered by the USA National Phenology Network, covering the period 2009–present for the United States and accessible via the Phenology Observation Portal and via an Application Programming Interface. The data described here have been used in diverse research and management applications, including over 30 publications in fields such as remote sensing, plant evolution, and resource management.<br><br><br><i>For all inquiries regarding this dataset, please contact the USA-NPN.

美国国家物候网络（USA National Phenology Network，USA-NPN）的目标是推进科学研究、为决策提供依据，并就物候学（phenology）及物种对环境变异与气候变化的响应与公众开展沟通和联系。USA-NPN旨在通过自由开放地提供物候信息，推动物候学学科发展并促进生态系统管理。为实现这些目标，USA-NPN国家协调办公室（National Coordinating Office，NCO）以多种格式提供动植物物候观测数据，包括经最小化处理的状态与强度数据集，以及针对单个植物、站点和区域的衍生物候指标（phenometrics）。本文档介绍了USA-NPN提供的观测数据产品套件，其覆盖2009年至今美国境内的数据，可通过物候观测门户（Phenology Observation Portal）及应用程序接口（Application Programming Interface）访问。本文所述数据已应用于各类研究与管理场景，包括在遥感、植物进化及资源管理等领域发表的30余篇学术论文。
