The US Pentagon is using cutting-edge sensors and software tests to protect against airborne hazards, including chemical and biological attacks. The system includes a multiscale weather forecast model, lidars, and other sensors to monitor air flow and turbulence around the building.
Researchers found that polar mesospheric clouds at the South Pole are on average 2 miles higher than those in the North, attributed to increased solar radiation. The clouds have brightened by 15% over the last twenty years, indicating a cooling of the mesosphere and potentially linked to long-term global climate change.
The Ohio State team is contributing to NASA's ICESat mission, which aims to map the Earth's ice sheets using a radar-like system. The team has developed lidar mapping software that will help calibrate the satellite's lidar system and create accurate maps of ice sheet extent.
Scientists have made groundbreaking measurements of upper atmosphere temperatures over the South Pole, revealing a significant discrepancy with global circulation model predictions. The findings suggest that wintertime warming due to sinking air masses is weaker than assumed, leading to extreme cooling in the lower stratosphere.
