SPLASH Field Study; Ott Disdrometer Raw & Stats Observations at Brush Creek, Colorado, 2021-10-19 to 2023-09-03 (NCEI Accession 0287380)

From fall 2021 through summer 2023, NOAA and research partners conducted a field study (SPLASH - the Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology). This field study established a state-of-the-art observing network in the East River watershed of the Colorado mountains with a goal of advancing weather and water prediction capabilities in areas with complex terrain. The ultimate goal of this project is improved prediction of weather and water in the Colorado mountains and beyond to inform societal preparedness and response. Among the instruments used in this study were disdrometers, which are optical instruments mounted on a tripod that use a laser to measure the size and fall speed of precipitation particles – such as raindrops, snowflakes, or hail – that fall through the laser beam. This archive consists of Disdrometer observations taken at the site at Brush Creek, Colorado. The raw observations and processed (stats) observations are included.

2021年秋季至2023年夏季，美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）及其合作研究机构开展了一项野外研究——SPLASH（水文气象降水、低层大气与地表研究，Study of Precipitation, the Lower Atmosphere and Surface for Hydrometeorology）。该研究在科罗拉多山脉东河流域搭建了一套最先进的观测网络，旨在提升复杂地形区域的天气与水文预报能力。本项目的最终目标是优化科罗拉多山脉及周边区域的天气与水文预报，为社会备灾与应急响应提供决策支撑。本次研究使用的观测仪器包含雨滴谱仪（disdrometer）：该类光学仪器搭载于三脚架之上，通过激光测量穿过激光束的降水粒子（如雨滴、雪花或冰雹）的粒径与下落速度。本数据集存档包含科罗拉多州布拉什克里克站点的雨滴谱仪观测数据，涵盖原始观测数据与经统计（stats）处理后的观测数据。
