Calculations of contiguous U.S. mean temperature are provided. Temperatures based on the USCRN network can be compared against national averages computed from other US datasets; an operational and research version of the U.S. Historical Climatology Network (USHCN) and the new US Climate Division dataset (nClimDiv).
This visualization shows a graph of soil moisture changes over time at a selected USCRN station. Five distinct layers on the screen show the volumetric water content (VWC) corresponding to soil depths 5, 10, 20, 50, and 100 cm. Since USCRN stations have three separate holes, the VWC shown is actually the average for the layer between all three holes. The display can be scaled to show relative wetness or dryness, which highlights change over the calendar period displayed, or absolute moisture status. Precipitation events are shown as bars above the soil moisture layers to illustrate the relationship between precipitation and soil moisture infiltration into the surface layer and downward percolation through the subsurface layers.
This visualization shows time series representing the ranges of volumetric water content (VWC) of the soil (as a percentage) at each of five depths. Since three independent measurements of VWC are made at each USCRN station, the time series is given a width which spans from the lowest VWC to the highest at each depth. When all three VWCs are nearly the same, the corresponding line is thin and opaque; when they are rather different, the line is wide and translucent. Both graph axes can be moved (mouse drag) or zoomed (shift-drag).
The National Integrated Drought Information System has created a line graph visualization of USCRN's soil moisture and temperature data, available on the drought.gov portal.
Multigraph line graphs of many other USCRN variables are available on the sensors page for each station (accessible from the observations page).
