Abstract:
|
Multiple decades of remote sensing data records have provided unprecedented spatial and temporal coverage in monitoring numerous components of the Earth system. The constellation of Earth-observing satellites is continually changing, and the processes being observed are changing as well. The remote sensing data record provides substantial opportunities for quantifying climate change, but these objectives often require the combined information from multiple remote sensing observing systems and understanding their operating characteristics over time. In addition, climate-relevant products from remote-sensing data result from multiple levels of data processing, including a retrieval step that involves inferring geophysical quantities from satellite spectra. This presentation will highlight uncertainty quantification approaches for Earth science data records from remote sensing and will emphasize specific challenges when working with multiple instruments. These challenges will be discussed in the context of the existing remote sensing record for atmospheric trace gases and for NASA's planned next-generation Earth System Observatory.
