CU Boulder researchers, >500 international colleagues launch yearlong journey to study Arctic climate.

NASA estimated extreme rainfall over eastern Texas from the remnants of Tropical Depression Imelda, using an algorithm that incorporates data from satellites and observations.

Observational data from radiosondes deployed in Antarctica improve the forecasting accuracy for severe Antarctic cyclones, according to a Japanese research team led by the Kitami Institute of Technology, Hokkaido, Japan.

During the week of Sept. 23, the U.S. Geological Survey Cascades Volcano Observatory, in cooperation with the U.S. Forest Service and Mount Hood National Forest, will install three new volcano monitoring stations on the flanks of Mount Hood.

Every year, the United States experiences dozens, if not hundreds, of natural hazard events that vary in size and impact from the incredibly large (like a hurricane or wide-spread flood) to the rather localized (like a sinkhole in a backyard)

In early October 2016, a tropical storm named Nicole formed in the middle of the Atlantic Ocean.

Tropical Storm Tapah formed quickly in the northwestern Pacific Ocean and as it was strengthening from a depression to a tropical storm, the Global Precipitation Measurement mission or GPM core satellite passed overhead from its orbit in space and measured rainfall rates throughout the storm.

NASA-NOAA’s Suomi NPP satellite imagery revealed Tropical Storm Mario appeared to be losing its rounded shape in the Eastern Pacific Ocean.

NASA has the unique capability of peering under the clouds in storms and measuring the rate in which rain is falling. 

NASA’s Aqua Satellite provided data on Major Hurricane Humberto that revealed its structure was changing as it was moving through the North Atlantic Ocean and past Bermuda.
