Impact/Purpose:
Our research objectives are to: (a) develop new methods using satellite remote sensor data for the rapid characterization of LC condition and change at regional to national scales; (b) evaluate the utility of the new NASA-EOS MODIS (Moderate Resolution Imaging Spectrometer) leaf area index (LAI) measurements for regional scale application with landscape process models (e.g., biogenic emissions and atmospheric deposition); (c) provide remote sensor derived measurement data to advance the development of the next generation of distributed landscape process-based models to provide a predictive modeling capability for important ecosystem processes (e.g., nutrients, sedimentation, pathogens, etc.); and (d) integrate in situ monitoring measurement networks with UAV and satellite based remote sensor data to provide a continuous environmental monitoring capability.
Description:
Remote sensing technologies are a class of instrument and sensor systems that include laser imageries, imaging spectrometers, and visible to thermal infrared cameras. These systems have been successfully used for gas phase chemical compound identification in a variety of field environments. Remote sensing and imaging technologies provide a tool to quickly identify the source of high leaking components by allowing the user to rapidly detect emissions, in some cases in real time. These capabilities allow an investigator to quickly scan large areas containing tens to hundreds of potential leaks. Imaging spectrometers and cameras can be deployed on fixed wing or helicopter platforms, which allows for emission monitoring over large areas. Some are very portable and can lend themselves to more detailed ground investigations of smaller areas.
