Spatial surface soil moisture can be an important indicator of crop conditions on farmland, but its continuous estimation remains challenging due to coarse spatial and temporal resolution of existing remotely-sensed products. Furthermore, while...

Recent measurements found high winter ozone (O3) at several locations in northeastern Utah's Uinta Basin. Similar to Wyoming's Upper Green River Basin, the area has seen recent growth in the gas/oil sector. As a part of a more comprehensive...
