Gridded Data Products
• Gridded Data Products (GDPs) are distributed here primarily to make these ferry-based measurements available (disclaimer) to researchers in a convenient and useful format. For example, numerical modelers can use the GDPs to improve fidelity of hydrodynamic simulations used for water quality management purposes.
• The GDPs have been created, from the raw measurements, through a series of processing stages including quality control that removes data not deemed of sufficient quality. For details, see the technical reports. (Download 2007 technical report as PDF.) (Download 2012 technical report as PDF.) [get free Adobe Acrobat Reader, needed to view PDF files]). To obtain data from other processing stages, email dcodiga@uri.edu. • The map below shows where the fixed GDP grid locations, or “virtual stations”, are located (superposed on the 20/40/60/80-meter bathymetric contours). There are 18 grid locations: 17 (named “R01” – “R17”) spanning The Race north to south, and one (named “G01”) in Plum Gut.  • GDPs consist of archived observations, to which additional data are periodically appended as they become available and undergo processing. In its present implementation this website is not intended to serve data in real time. To date, the most recent data in the GDPs are from June 2011. The velocity sampling periods span from late 2002 through 2006 and from April 2010 through early June 2011. The water properties sampling periods span from early summer 2005 to late summer 2006 (temperature, salinity, and Chlorophyll) and from April 2010 through early June 2011 (temperature and salinity, not Chlorophyll).
