NOAA Center for Tsunami Research Page provides current environmental measurements, used to as input into models that provide accurate forecasts to better prepare everyone for the hazards of tsunamis. It provides assessments for parts of the U.S. most vulnerable to tsunamis, including Hawaii, California, Alaska, Oregon, and Washington. http://nctr.pmel.noaa.gov/

NOAA's National Severe Storms Laboratory serves the nation by working to improve the leadtime and accuracy of severe weather warnings and forecasts in order to save lives and reduce property damage. Current projects include work on the Polarimetric Doppler Radar (or dual polarization radar), which will greatly improve hazardous weather forecasts and warnings. http://www.nssl.noaa.gov/

Geophysical Fluid Dynamics Laboratory (The Shrinking Arctic Ice Cap) focuses on the development of climate models and computer simulations in order to improve understanding the behavior of the atmosphere, oceans, and the global climate system. The Web site hosts an image gallery on the arctic ice cap to show the shrinkage of the ice over the years and the average amount of ice lost in a three month period. http://www.gfdl.noaa.gov/the-shrinking-arctic-ice-cap-ar4

NOAA's Great Lakes Environmental Research Laboratory conducts research on ecosystem forecasting. This type of forecasting predicts the effects of chemical, physical, biological and human-induced changes on ecosystems. Although based in the Great Lakes Basin, this laboratory does research for other parts of the United States, such as Vermont, Louisiana and Idaho — and even in Canada. http://www.glerl.noaa.gov/
