These experimental images are intended to be used as short-term and long-term drought assessment tools for the Arkansas-Red basin.
The Historical Climate Trends Tool, from the Southern Climate Impacts Planning Program, displays precipitation and temperature trends for the period of the instrumental record, 1895-Present. Users can view the long term average, 5-year moving average, and yearly average by state, climate division and season for any state in the United States. The data, which are provided by the National Climatic Data Center, are displayed via a graph and a mouse-over function allows the user to view yearly values.
The Southern U.S. Drought Tool, from the Southern Climate Impacts Planning Program, displays information on drought severity and the amount of precipitation needed to get out of drought. The tool is useful for someone who is interested in understanding precipitation deficits, or lack thereof, over a relatively short period of time (365 days or less). Users can view precipitation statistics (e.g., rainfall total, departure from normal, % of normal, and standard precipitation index) by climate division for any state in the SCIPP region. Users can also select an end date and the time period (30, 60, 90, 180, 365 days) for which they would like to view the information. Data are provided in table and map formats, and “Normal” is based on 1971-2000 averages.
VegDRI maps are produced every two weeks and provide regional to sub-county scale information about drought’s effects on vegetation. The VegDRI calculations integrate satellite-based observations of vegetation conditions, climate data, and other biophysical information such as land cover/land use type, soil characteristics, and ecological setting. The National Drought Mitigation Center produces VegDRI in collaboration with the US Geological Survey, and the High Plains Regional Climate Center, with sponsorship from the US Department of Agriculture.
The National Weather Service, part of the National Oceanic and Atmospheric Administration, provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters, and ocean areas.
The U.S. Drought Portal provides current drought information, impacts, forecasts, and reports by state or region, along with supplemental tools to aid in education, planning, recovery, and research.
ForWarn is a satellite-based forest disturbance monitoring system for the conterminous United States. It delivers new forest change products every eight days and provides tools for attributing abnormalities to insects, disease, wildfire, storms, human development or unusual weather. Archived data provide disturbance tracking across all lands since 2000.
