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

browse graphicPreview graphic
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.

Purpose 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. Anticipated Benefits: In combination with scientific analysis of the resulting datasets, research will apply SPLASH observations and the resulting enhanced process-understanding to evaluate and improve NOAA's latest suite of modeling tools, including the Unified Forecast System, Rapid Refresh Forecast System, and National Water Model. The ultimate goal of this project will be improved prediction of weather and water in the Colorado mountains and beyond to inform societal preparedness and response.
