"A synthesis of multiple indices, outlooks and news accounts, representing a consensus of federal and academic scientists" from USDA, the Department of Commerce, the Department of the Interior and the National Drought Mitigation Center (NDMC).
DOC. National Oceanic and Atmospheric Administration.
Ensures "collaboration between different government agencies on drought-related issues" and gives information on current drought conditions, forecasting, impacts and more.
USDA. Agricultural Research Service.
The Evaporative Stress Index (ESI) describes temporal anomalies in evapotranspiration (ET), highlighting areas with anomalously high or low rates of water use across the land surface.
Earth System Research Laboratory. NOAA.
"The Evaporative Demand Drought Index (EDDI) is an experimental drought monitoring and early warning guidance tool. It examines how anomalous the atmospheric evaporative demand (E0; also known as "the thirst of the atmosphere") is for a given location and across a time period of interest."
DOC. NOAA. National Weather Service.
"Provides new forecast products (including visual displays) depicting the magnitude and uncertainty of occurrence for hydrologic events from hours to days to weeks."
DOC. NOAA. National Environmental Satellite, Data, and Information Service.
Focuses its work toward "drought variability for the last ca. 100 years based on instrumental data, and on the last several centuries and millennia based on paleoclimatic proxy data." Related information can be found through NOAA's Paleoclimate Drought Resources page.
DOI. United States Geological Survey.
A compilation of ''maps and graphs of current water resources conditions'' including daily streamflow condition maps. Daily streamflow condition maps depict streamflow conditions as measured at United States Geological Survey (USGS) gaging stations. Please note that "the real-time data used to produce the maps are provisional and have not been reviewed or edited. The data may be subject to significant change."
USDA. Risk Management Agency.
A clearinghouse of weather information for agriculture.
USDA. Joint Agricultural Weather Facility.
Contains "weekly national agricultural weather summaries, including the weather's effect on crops; summaries and farm progress for 44 states and the New England area. This report includes any corrections to the Crop Progress data released the previous day."
World Meteorological Organization. Global Water Partnership.
"This Handbook of Drought Indicators and is based on available literature and draws findings from relevant works wherever possible. The handbook addresses the needs of practitioners and policymakers and is considered as a resource guide/material for practitioners and not an academic paper. This publication is a ‘living document’ and will be updated based on the experiences of its readers."
