PACE Applications to Case II Waters: Quantifying the Uncertainty in Inherent Optical and Water Constituent Properties and the Impact On Remotely Sensed Ocean Color

PI: Steven Ackleson - Naval Research Laboratory
In response to solicitation NNH13ZDA001N-PACEST, Pre-Aerosol, Clouds, and Ocean Ecosystem (PACE) Science Team, we propose to investigate uncertainties in Case II inherent optical properties (IOPs) and associated water constituent properties (e.g., concentration, composition, and morphology) and to examine the impact of uncertainties on recommended PACE data products for coastal ocean, estuarine, and inland waters. These objectives strongly address ocean color science needs articulated within the PACE Mission Science Definition Team Report (October 2012) pertaining to marine biogeochemical cycles associated with land-ocean interactions in response to climate change. As a collaborative member of the IOP working group (ST/IOP), we will utilize existing in situ and remotely sensed data sets as well as new observations to be collected during the period of performance through existing and planned field campaigns. Uncertainties will be estimated through direct comparisons of optical and water constituent properties measured or derived through independent means, comparisons of functional relationships between associated parameters with relationships that have been published and vetted by the research community, and through tests of optical closure. In addition to the proposed research and collaborations with other members of the ST/IOP, the PI, Dr. Steven Ackleson, proposes to be the overall PACE Science Team leader. Working closely with NASA-appointed representatives, Dr. Ackleson will be responsible for organizing, planning, and chairing team meetings, coordinating focused working groups, integrating results, building consensus on PACE science objectives and requirements, representing science team activities at professional meetings and symposia, and preparing progress reports and consensus statements as directed by NASA.
