A new NASA satellite mission, CYGNSS (Cyclone Global Navigation Satellite System), combines the all-weather performance of GNSS bistatic ocean surface scatterometry with the sampling properties of a constellation of satellites. This will result in spatial and temporal sampling properties which are markedly different from conventional imagers.
Data Drives Everything (But the Bridges Need a Lot of Work)
In a world driven by data, finding new ways to share information is critical to progress in all fields. With the Research Data Alliance, Dr. Francine Berman is hoping to change the way data is collected, used, and shared to solve problems around the globe.
A Brief History Of Radio – Echo Sounding Of Ice
The application of radio-echo sounding (RES) to thickness measurements of glacial and sheet ice has been demonstrated since the early 1960s. The concept for this approach can be traced to 1933 at Admiral Byrd’s base, Little America, Antarctica where the first indication that snow and ice are transparent to high frequency radio signal was observed.
How and why does the Sun’s energy change, and how does the Earth respond? We care about these changes, and seek improved understanding of their causes and consequences. We do this because society urgently seeks to quantify anthropogenic and natural causes of climate change, because we are increasingly reliant on the technological benefits of space assets, and because we utilize and explore extensive environmental domains well beyond the surface where we live.
