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. For all inquiries regarding this dataset, please contact the USA-NPN. This data is subject to the USA-NPN's Data Use Policy.

美国国家物候网络（USA National Phenology Network, USA-NPN）的核心目标是推动物候学（phenology）领域的科学发展、为决策提供信息支撑，并面向公众开展物候学及物种对环境变化与气候变化响应相关的科普与交流活动。该网络致力于推进物候学研究，并通过免费开放共享物候相关信息，助力生态系统管护工作。为达成上述目标，美国国家物候网络国家协调办公室（National Coordinating Office, NCO）提供多种格式的动植物物候观测数据，包括经过最小化处理的物候状态与强度数据集，以及针对单株植物、监测站点与区域的衍生物候指标（phenometrics）。本文件详细介绍了美国国家物候网络所发布的整套观测数据产品，其覆盖美国境内2009年至今的观测数据，可通过物候观测门户（Phenology Observation Portal）与应用程序编程接口（Application Programming Interface, API）获取。本文所述数据集已被广泛应用于多类研究与管理场景，涵盖遥感、植物演化、资源管理等领域的30余篇学术出版物。若有关于该数据集的任何咨询事宜，请联系美国国家物候网络。本数据集需遵守美国国家物候网络的数据使用政策。
