Global Vegetation Health Products

The vegetation health  products can be used as proxy data for monitoring vegetation health, drought, soil saturation, moisture and thermal conditions, fire risk, greenness of vegetation cover, vegetation fraction, leave area index, start/end of the growing season, crop and pasture productivity, teleconnection with ENSO, desertification, mosquito-borne diseases, invasive species, ecological resources, land degradation, etc. 

Integrated Surface Database

Compiles global hourly and synoptic observations from numerous sources into a single common ASCII format and common data model.  Station data available worldwide with some data as far back as 1901. Over 11,000 stations are currently "active" and updated daily. Includes many parameters such as wind speed & direction, wind gust, temperature, dew point, cloud data, sea level pressure, altimeter setting, station pressure, present weather, visibility, precipitation amounts for various time periods, snow depth, and more.

Comparative Climatic Data

These data tables of meteorological elements outline the climatic conditions at major weather observing stations in all 50 states, Puerto Rico, and Pacific Islands. The data are from observing sites presently in use or include data from former sites that are comparable in exposure. Stations having less than 3 years of data for the current operating site are omitted from the tables of observed data.

Climatological Data

Monthly editions contain station daily maximum and minimum temperatures and precipitation. Some stations provide daily snowfall, snow depth, evaporation, and soil temperature data. Each issue also contains monthly summaries for heating and cooling degree days (65 degrees Fbase). The July issue also contains monthly heating degree days and snow data for the preceding July through June. The annual issue contains monthly and annual averages of temperature, precipitation, temperature extremes, freeze data, soil temperatures, evaporation, and a recap of monthly cooling degree days.

Local Climatological Data

A monthly summary from major airport weather stations that includes a daily account of temperature extremes, degree days, precipitation and winds. Also included are the hourly precipitation and abbreviated 3-hourly weather observations.

Regional Snowfall Index

NOAA produces the Regional Snowfall Index (RSI) for significant snowstorms that impact the eastern two-thirds of the United States. The RSI ranks snowstorm impacts on a scale from 1 to 5, similar to the Fujita scale for tornadoes or the Saffir-Simpson scale for hurricanes.

 

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.

Tornado Climatology

This online resource examines tornado activity across the United States across temporal and spatial scales. The contiguous United States is the most active tornado region in the world, with an average of 1,253 tornadoes occurring annually. The information and data provided here serves as a baseline for comparing current tornado activity to the past, providing a complete historical perspective.

International Best Track Archive for Climate Stewardship (IBTrACS)

NOAA’s IBTrACS system provides tropical cyclone best-track data in one centralized location to aid understanding of the distribution, frequency, and intensity of tropical cyclones worldwide.

U.S. Heat Stress Index

When both temperature and humidity are high, humans can experience considerable heat stress. In the U.S., extreme heat may have greater impact on human health, especially among the elderly, than any other type of severe weather.
