All measurements are volumetric soil moisture. Surface soil moisture is the daily average of measurements at 0-5 cm depth,
and root zone soil moisture (RZSM) is the daily average of measurements at 0-100 cm depth. The shaded area around the line
in the graph represents the range of daily volumetric soil moisture. The data shown represent either the value of a point
location or the mean value within a particular 9km grid cell.
