Sevilleta Field Station Meteorological Network (SevMET): High frequency measurements from the Sevilleta Field Station Meteorological Station (FSTN), Sevilleta National Wildlife Refuge, NM, USA, 2024-ongoing.

The Sevilleta Field Station Meteorological Network (SevMET) is a spatially distributed, long-term climate monitoring network established to enhance and expand climate monitoring across a variety of dryland ecosystems (e.g., grasslands, shrublands, woodlands) within the Sevilleta National Wildlife Refuge in central New Mexico. Ecosystem processes in drylands are strongly regulated by climatic drivers that are highly variable in space and time, both within and among years. Therefore, accurate measurement of environmental variables at high spatial and temporal resolution is fundamental to understanding biophysical processes in these ecosystems. SevMET consists of fifteen standardized research-grade weather stations located across multiple dryland ecosystem types (e.g., grasslands, shrublands, woodlands) representative of the southwestern US. Stations continuously measure a standard suite of meteorological variables at five-minute intervals, including air temperature, relative humidity, precipitation, photosynthetically active radiation, incoming shortwave radiation, wind speed and direction, dew point, vapor pressure, and, at a subset of stations, barometric pressure. Stations also measure a suite of soil parameters (bulk electrical conductivity, dielectric permittivity, temperature, and volumetric water content) at six depths (5, 10, 20, 30, 40, and 50 cm) below the ground surface using 1-2 integrated soil profilers. Additionally, phenocams at each station capture images at thirty-minute intervals during daylight hours. This data package contains high-frequency meteorological measurements from the Sevilleta Field Station Meteorological Station (FSTN). Phenocam images can be accessed through the PhenoCam Network at: https://phenocam.nau.edu/webcam/sites/sevmetfstn/. These data complement and extend meteorological data recorded by an adjacent station (Met01), accessible at: https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-sev&identifier=1.塞维列塔野外站气象网络（Sevilleta Field Station Meteorological Network，简称SevMET）是一套空间分布式长期气候监测网络，旨在强化并拓展新墨西哥州中部塞维列塔国家野生动物保护区内各类旱地生态系统（如草原、灌丛、林地）的气候监测工作。旱地生态系统的过程受气候驱动因子强烈调控，而这些驱动因子在年际与年内的空间和时间维度上均存在高度变异性。因此，以高空间与时间分辨率精准测定环境变量，是理解此类生态系统生物物理过程的核心基础。 该气象网络由15座标准化科研级气象站组成，分布于代表美国西南部的多种旱地生态系统类型（如草原、灌丛、林地）中。各站点以5分钟为间隔持续采集一套标准气象变量数据，涵盖气温、相对湿度、降水量、光合有效辐射、入射短波辐射、风速与风向、露点温度、水汽压，部分站点还可测量气压。此外，各站点通过1~2台集成式土壤剖面仪，在地表以下6个深度（5、10、20、30、40、50厘米）处采集一系列土壤参数，包括体积电导率、介电常数、土壤温度与体积含水量。每个站点均配备物候相机（phenocam），可在日间以30分钟为间隔拍摄图像。 本数据包包含来自塞维列塔野外站气象站（Sevilleta Field Station Meteorological Station，简称FSTN）的高频气象监测数据。物候相机图像可通过物候相机网络（PhenoCam Network）获取，访问链接为：https://phenocam.nau.edu/webcam/sites/sevmetfstn/。本数据集可补充并拓展相邻站点Met01所记录的气象数据，该站点数据的访问链接为：https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-sev&identifier=1。
