measurement. L2P confidence data are required to:<br />
48 WP2-051 1. Derive a quantitative ‘confidence value’ for each SST measurement that is used to identify reduced quality data. NASR<br />
48 WP2-052 2. Derive and interpret of SSES values assigned to each SST measurement. NASR<br />
48 WP2-053 3. Force parameterisations that estimate diurnal variability. NASR<br />
48 WP2-054 Using confidence data, Sensor Specific Error Statistics (SSES) are assigned to each SST measurement based on analysis<br />
L2P.0050<br />
of the GHRSST-PP Match-up <strong>Data</strong>base (MDB) system described in WP-ID3.<br />
48 WP2-055 A L2P data file is generated (format described in Appendix A1.4) which contains the original SST data together with pixel<br />
L2P.0060<br />
confidence data. L2P data files are formatted as GDS netCDF files (WP-ID1.2.3) that are fully described in Appendix A1.<br />
48 WP2-056 For each L2P data file a MMR_FR metadata record (described in Appendix A6) is generated and registered at the MMR<br />
ING.0030<br />
under the appropriate MMR_DSD.<br />
48 WP2-057 L2P data files and pixel confidence data are identical in format for all input SST data streams with differs between the IR<br />
L2P.0060<br />
and MW SST data exist. Using a single data format for all SST data files greatly facilitates SST inter-comparison and<br />
merging activities within the GHRSST-PP.<br />
48 WP-ID2.1 Pre-processing and merging of auxiliary data.<br />
48 WP2-058 This work-package describes in detail common pre-processing operations performed on each IR and MW SST data file.<br />
MRG.0020<br />
Figure 5.2.1 provides a functional breakdown diagram that identifies each common pre-processing pixel based operation.<br />
These are:<br />
48 WP2-059 Check that the SST value lies within acceptable limits, if not then reject the data file QLC.0070<br />
48 WP2-060 Compute the pixel measurement time ING.0070<br />
48 WP2-061 Assign a fractional sea ice value if required MRG.0030<br />
48 WP2-062 Assign a wind speed value MRG.0040<br />
48 WP2-063 Assign a surface solar irradiance (SSI) value MRG.0050<br />
