Atmospheric Surface Flux Station #30 measurements (level 1 Raw), Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology (SPLASH), September 2021-July 2023

Raw (Level 1) measurements from the Atmospheric Surface Flux Station #30 (ASFS-30) deployed at the Kettle Ponds Annex site (38°56.3686' N, 106°58.1781' W) during the Study of Precipitation, the Lower Atmosphere, and Surface for Hydrometeorology (SPLASH) campaign near Gothic, Colorado, from September 2021 through July 2023. The ASFS measured variables comprising the surface energy budget, surface momentum flux, near-surface meteorology, and soil properties. These measurements are included in three netCDF files per day. The "slow" files are for 1-minute averages of the measured variables, including near-surface meteorology, surface height change (due to accumulating/ablating snow), and upwelling and downwelling shortwave and longwave radiative fluxes. The "fast" files are for data at 20 Hz resolution including 3-dimensional wind, temperature, and gas concentrations of water vapor and carbon dioxide. These data are raw measurements with technical corrections applied but no quality assurance. A detailed documentation of the measurement will be provided in a forthcoming publication. For scientific purposes, we recommend using the Level 2 data files when they are available, as these will include full quality control as well as higher-order derived products.本数据集为2021年9月至2023年7月期间，部署于科罗拉多州哥特镇附近壶塘附属观测点（北纬38°56.3686'，西经106°58.1781'）的大气地表通量站30号（ASFS-30）在“水文气象学降水、低层大气与地表研究计划（SPLASH）”科考项目中获取的原始（Level 1）观测数据。该观测站的观测变量涵盖地表能量收支、地表动量通量、近地表气象要素以及土壤特性。每日的观测数据存储于3个网络通用数据格式（netCDF）文件中。“慢速”文件存储观测变量的1分钟平均值，涵盖近地表气象要素、地表高度变化（由积雪累积/消融导致）以及上行、下行短波与长波辐射通量。“快速”文件存储20 Hz分辨率的观测数据，涵盖三维风场、气温以及水汽与二氧化碳的气体浓度。本数据集为经过技术校正的原始观测数据，但未经过质量控制流程。该观测项目的详细文档将在后续发表的论文中公开。出于科学研究目的，建议在可用时使用二级（Level 2）数据文件，此类文件已完成完整的质量控制，并包含高阶衍生产品。
