Recent advancements in remote sensing technologies, such as lidar and high fidelity imaging spectroscopy, enable researchers to study ecological systems at multiple levels. These tools provide essential information for characterizing landscape dynamics and quantifying ecosystem functions related to biogeochemical cycling.
Researchers at Woods Hole Research Center are using laser remote sensing (lidar) to study biological diversity and predict bird species richness. Lidar data provides unique measurements of vegetation structure, which is linked to habitat complexity and animal species richness.
The U.S. Geological Survey's Coastal and Marine Geology Program investigates the extent and causes of coastal impacts of hurricanes and extreme storms on U.S. coasts. NASA technology provides rapid assessment of coastal conditions, supporting USGS research programs and emergency response agencies.
Researchers have completed the most meticulous survey ever made of the San Andreas Fault, revealing detailed features that were previously unseen. The 'B4' Project used ultra-high-resolution global positioning system (GPS) technology and a radar-like system called lidar to map the fault with 5-centimeter vertical resolution.
Airborne LiDAR technology has been successfully used to monitor and protect rare species such as California spotted owls and Delmarva fox squirrels. The system provides detailed measurements of forest canopy, tree height and biomass, enabling researchers to identify suitable habitats for endangered species.
Scientists used airborne LIDAR to map the dimensions of Mount St. Helens' uplift, creating detailed models to forecast volcanic hazards. The analysis revealed 5.3 million cubic meters of volume change in the area of uplift, confirming photogrammetric measurements.
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.
