Hurricane Forecasts Rely on Modeling the Past
988 Views0 Comments0 Likes
Improving hurricane forecasts means testing historical storms with today's sophisticated models and supercomputers. NASA and NOAA work together in gathering ground and satellite observations, as well as experimenting with research forecast models. As a result of this collaboration, model resolution has increased, and scientists are discovering more about the processes that occur within these powerful storms. The Global Precipitation Measurement (GPM) Mission is a joint NASA and Japan Aerospace Exploration Agency (JAXA) mission that measures all forms of precipitation around the globe. GPMs Microwave Imager, or GMI, has proven useful in seeing beneath the swirling clouds and into the structure of tropical cyclones. The information gathered by GPM and other missions will be used to improve forecast models.

Wildlife habitats close to airports pose a serious risk to safety at takeoff and landing. A new service lets airports use Earth-observation satellites to identify and manage these areas.
TOPEX/JASON Sees 22-Year Sea Level Rise

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1, and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches. The color range for this visualization is -7 cm to +7 cm (-2.76 inches to +2.76 inches), though measured data extends above and below 7cm(2.76 inches). This particular range was chosen to highlight variations in sea level change. Download the visualization: http://svs.gsfc.nasa.gov/cgi-bin/deta....

Data from Landsat satellites, a joint mission of NASA and the U.S. Geological Survey, have been critical to helping the Jane Goodall Institute in their work to protect chimpanzees and their habitat. In this video, Goodall and JGI scientist Lilian Pintea discuss the transformational role of seeing changing habitats from above.
