In support of Lake Mendocino Forecast Informed Reservoir Operations (FIRO), CW3E has partnered with USACE, NOAA, Sonoma Water, and local landowners to add six meteorological stations to the Lake Mendocino watershed in the upper Russian River watershed in northern California. Additions in support of Yuba-Feather FIRO, in partnership with the Yuba Water Agency, CA Department of Water Resources, USACE, the Feather River College, and other local landowners, are currently ongoing. These stations measure temperature, relative humidity, pressure, precipitation, and soil moisture and temperature at six levels. Data are collected every two minutes. The plots here represent raw data from the stations and have not undergone any quality control. Plots are updated once per hour. Please direct any questions and requests for past and/or QC’d data to firstname.lastname@example.org.
Email alerts for extreme precipitation within the Yuba and Feather River watersheds are available for the CW3E deployed stations. For more information and to sign up for these alerts click here.
Plot description: Surface meteorological and soil data observed at the location highlighted in the map. Top panel shows temperature (°F; blue line) and relative humidity (percentage; red line), second panel shows surface pressure (hPa; black line) and solar radiation (W/m2; green line), third panel shows wind speed (line; m/s) and direction (vectors), fourth panel shows hourly precipitation (inches; blue bars) and accumulated precipitation during the period shown (inches; red line), fifth panel shows the soil moisture (fraction) at various depths (color denoted by legend on right), and the bottom panel shows the soil temperature (°F) at the same depths as soil moisture. For an archive of raw data and images use FTP to connect to sioftp.ucsd.edu and navigate to /CW3E_DataShare/CW3E_SurfaceMetObs for data and /CW3E_DataShare/CW3E_SurfaceMetImages for images.
Plot description: Accumulated precipitation (mm on left axis, inches on right axis) measured at the above the locations during the current water year (1 October – current day).
Plot description: The following images show data from vertically pointing MicroRain Radars (MRRs) deployed by CW3E. Each plot shows color shading of reflectivity, in the top panel, and vertical velocity in the bottom panel. MRR data are processed using an algorithm based on Maahn and Kollias 2012 but modified to improve the representation of heavy rain. Black circles represent the freezing level indicated by a radar bright band when bright band precipitation is present. The bar at the bottom of each chart shows the precipitation type (bright band, hybrid, or non-bright band) using an algorithm modified from White et al. 2003. Each plot shows the current day’s data, updated once per hour, with time moving from left to right. Time is in UTC. For more information on these radars click here.

Plot description: The plots below shows data collected from a disdrometer deployed by CW3E at the location highlighted on the map. The top panel shows a scatter plot of rain intensity (mm/h) and the middle panel shows the radar reflectivity (dBZ). For the top two panels, the points are shaded according to the precipitation class determined by the disdrometer (see legend). The bottom panel shows the drop size distribution: the volume equivalent diameter (mm) is on the vertical axis, while each bin is shaded by the drop size frequency, which is expressed as a spectral number density (log scale). Measurements are recorded every 10 seconds. Each plot shows the current day’s data, updated once per hour, with time moving from left to right. Time is in UTC.
