Contours are not rendered during times of limited data coverage
(i.e. soil moisture fields during winter). Shaded contours,
when available, provide a regional perspective, but may not
accurately reflect conditions in areas separated from USCRN
stations by distance and/or topography (elevation/land cover).
Figures update hourly and represent most recent conditions
(three-hours-ago due to timing of satellite transmissions). If
communications are down figures may not update. Coordinated
Universal Time (UTC) is used for consistency.
