2.2 USA National Integrated <strong>Drought</strong> Information System 5<br />
The US National Integrated <strong>Drought</strong> Information System (NIDIS) is <strong>the</strong> national drought<br />
early warning system for <strong>the</strong> US. It employs three key tools: 1) <strong>the</strong> US <strong>Drought</strong> Monitor 6 (; 2)<br />
<strong>the</strong> <strong>Drought</strong> Impact Reporter 7 ; and 3) <strong>the</strong> US <strong>Drought</strong> Outlook , and hundreds of supplemental<br />
indicators, services, forecasts, and tools, to provide a snapshot of current drought conditions,<br />
how those conditions are affecting local populations, and whe<strong>the</strong>r <strong>the</strong> drought will continue.<br />
2.2.1.1 USA NIDIS Portal Drill-Down Capability<br />
One interesting feature of <strong>the</strong> NIDIS map server is that one begins with a national map of<br />
drought conditions within <strong>the</strong> USA and <strong>the</strong>n “drills down” to <strong>the</strong> region level and <strong>the</strong>n to <strong>the</strong><br />
basin level.<br />
The first drop down tab is “<strong>Drought</strong> monitor date,” while <strong>the</strong> second is “Zoom to area.” The<br />
third drop down tab is “Zoom to basin,” which currently includes <strong>the</strong> Upper Colorado River<br />
Basin and <strong>the</strong> Lower Colorado River Basin.<br />
Such a “drill down” system—used by both <strong>the</strong> European <strong>Drought</strong> Observatory and <strong>the</strong><br />
USA National Integrated <strong>Drought</strong> Information System portal—can integrate <strong>the</strong> basin scale<br />
drought maps, national scale, continental scale, and global scale and, correspondingly, was<br />
selected for implementation within <strong>the</strong> <strong>Global</strong> <strong>Drought</strong> <strong>Monitoring</strong> Portal.<br />
2.2.1.2 Soil Moisture <strong>Monitoring</strong> for Agricultural <strong>Drought</strong><br />
As in <strong>the</strong> case of EDO, <strong>the</strong> USA National Integrated <strong>Drought</strong> Information System<br />
(NIDIS) contains soil moisture and soil moisture anomaly maps. 8<br />
