The GHRSST-PP Diagnostic Data Set (HR-DDS): Essential Ocean Tools
Accurate knowledge of SST across the Earth is essential for GHRSST-PP applications including weather prediction, ocean forecasting and climate change monitoring. Through careful analysis , verification and vlaidation of the differences between SST datasets GHRSST-PP teams can improve the quality of all measurements.
Every day satllite instruments make millions of measurments of (SST) across the entire planet. Some sensors can see through cloud but are less accurate, some observe only a small area but wth near perfect accracy and some see the same region of ocean every 15 minutes. In order use these different SST observations we must understand and quantify the differences between them. This is the aim of the HR-DDS system.
High Resolution Diagnostic Data Sets (HR-DDS) are small subsets of Sea Surface Temperature data from many different sources.These subsets are extracted for specified sites distributed across the World's oceans. Their locations are chosen to facilitate intercomparison of SST in a wide variety of conditions.
The National Oceanography Centre, Southampton (NOCS) hosts this service for European Space Agency (ESA) DUE project Medspiration as a contribution to the GODAE High Resolution Sea Surface Temperature Pilot Project (GHRSST). Satellite data are provided by the Medspiration Project, the National Centre for Ocean Forecasting (NCOF) in the UK and the GHRSST Global Data Assembly Centre (GDAC). The analysis software is a contribution to the EU MERSEA Project.
