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).
This visualization shows maps of daily or hourly solar radiation totals at USCRN stations. On the Daily View solar page, brightness
of the icons reflects the daily total at each station as a percent of maximum possible solar radiation for that day. Rolling over a
station symbol reveals the numerical value of the daily solar radiation, and displays a time series graph of hourly totals in the
lower left. Pressing the Hourly View button on the upper left of the map displays symbols representing the amount of solar radiation
received in the last hour, which can be animated forward or backward in time at various speeds using the slide tool.
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).
