Residential Energy Demand Temperature Index (REDTI)

This index is based on population-weighted heating- and cooling-degree days. The REDTI tool is valuable for explaining year-to-year fluctuations in energy demand for residential heating and cooling.

Ultraviolet Index Forecast Bulletin and Map

NOAA's Climate Prediction Center provides daily forecast maps of Ultraviolet (UV) Index for 58 U.S. cities, colored coded to their anticipated level of exposure. According to the World Health Organization, prolonged exposure to the sun's UV radiation may result in acute and chronic health effects on our skin, eyes, and immune system.

U.S. Hazards Outlooks

A summary of forecast and hazards—including extreme heat & cold, flood & drought, winds and severe weather—for 3-7 days as well as 8-14 days into the future.

National and Local Weather Hazards

The National Weather Service provides weather, water, and climate data, forecasts and warnings for the protection of life and property and enhancement of the national economy. These products include forecast and warnings of environmental events that can impact human health, such as excessive heat, flooding, severe cold, and more.

U.S. Snow Climatology

Here you can access snowfall and snow depth statistics for several thousand non-airport stations in the National Weather Service (NWS) Cooperative (COOP) Network across the contiguous U.S. and Alaska. Data are available for daily, monthly, and seasonal snowfall and snow depth totals, which are useful in economic and engineering decision-making, and provide the Federal Emergency Management Agency (FEMA) with an objective basis for declaring federal snow disasters.

U.S. Drought Monitor

Drought is one of the most costly natural disasters affecting the United States. The National Integrated Drought Information System (NIDIS) helps the nation and North America understand and proactively prepare for drought by providing data and information about the extent and potential impacts of drought and associated risks. The system provides a variety of decision support tools to help people prepare for and mitigate the effects of drought.

Atlantic Hurricanes and Climate

This document, developed by numerous NOAA researchers, presents the state of the science regarding the links between Atlantic hurricane activity and climate variability and change.

Aerosols and Climate

Improving our understanding of the impacts of aerosols on Earth's climate is essential for providing accurate climate forecasts and the information needed to cope with (adaptation) and reduce (mitigation) climate change. 

Ocean Acidification

Ocean acidification will have long-term implications for the global carbon cycle and climate, as well as coastal and marine ecosystems. 

Drought

Droughts are a common feature of U.S. climate and are among the most damaging of all natural hazards, with annual economic losses for the U.S. often in the billions of dollars.
