NASA Workshop for Remote Sensing of Coastal and Inland Waters

EOS meeting report article (PDF)

Coastal and inland water bodies have great value for recreation, food supply, commerce, transportation, and human health and have been experiencing external pressure from direct human activities and climate change. Given their societal and economic value, understanding issues of water quality, water quantity and the impact of environmental change on the ecological and biogeochemical functioning of these water bodies is of interest to a broad range of communities. Remote sensing offers one of the most spatial and temporally comprehensive tools for observing these waters. While there have been some success with remotely observing these water bodies, there still remains many challenges within this system that include algorithm performance, atmospheric correction, the relationships between optical properties and biogeochemical parameters, sufficient spatial and spectral resolution, and a lack of uncertainty estimates over the wide range of environmental conditions encountered across these coastal and inland water bodies.

The workshop will focus on the remote sensing aspects that pertain to environmental change in optically complex coastal and inland lake waters. The scope will be limited to products that can be derived from visible spectral reflectance (i.e. aquatic color) and infrared emissivity (i.e. surface temperature) and the science considerations surrounding these products. The workshop aims to summarize the current state of remote sensing in these complex waters, identify gaps in knowledge and data needs, identify priorities and provide a framework for near- and long-term science goals for remote sensing relevant to the quantification of environmental change in near coastal and inland water bodies. These topics will be reviewed in the context of both U.S. and international science activities. In short, the goals are to:

The workshop will cover topics including, products that are currently able to be retrieved, algorithm refinement and development for improved and desired products, spectral/spatial/temporal limitations and needs, relationships between optical and biogeochemical properties, atmospheric correction, uncertainty considerations, in situ data availability and needs, planning for full utilization of forthcoming sensors with improved spatial, spectral and temporal resolution. Specifically the workshop will aim to address the following research questions:
