82 WP4-032 a HR-DDS MMR_FR prepared and submitted to the HR-DDS MMR system (WP-ID4.7). NASR<br />
82 WP4-033 There are several schemes that have been developed by operational agencies and research establishments (e.g.,<br />
Reynolds and Smith) that could be used but in each case, the specific method must be adapted to the high resolution<br />
L4A.0080<br />
L4A.0095<br />
space scales that the GHRSST-PP is attempting to resolve<br />
82 WP4-034 it is expected that L4 data products will evolve as RDAC gain more experience with high resolution SST measurements. L4A.0090<br />
WP-ID4.1 Collation of Available L2P <strong>Data</strong><br />
83 WP4-035 all L2P data eligible for analysis must first be collated. L4A.0030<br />
83 WP4-036 L2P data must then be mapped into the analysis grid. L4A.0050<br />
84 WP4-037 L2P data must first be re-sampled onto the L4FND standard output grid which is defined in Appendix A1.1. NASR<br />
84 WP4-038 A number of input sensors (infrared imagers) have finer spatial resolution than the output grid specification, as shown in<br />
L4A.0060<br />
Figure 4.1.1. For these cases the rule will be to average the values of all pixels which overlap the product cell entirely and<br />
which have a L2P confidence record Proximity_Confidence value equal to the highest encountered within the cell, to<br />
produce a single value<br />
84 Rule 4.1a WP4-039 In the case of a smaller L2P input pixel than the L2FND grid cell size, L4FND data product cell values are derived from an<br />
L4A.0060<br />
average of the L2P pixel which completely overlap the product cell and which have a L2P confidence record<br />
Proximity_Confidence value equal to the highest encountered within the cell, to produce a single value.<br />
84 Rule 4.1b WP4-040 For input pixels that straddle the boundary between output grid cells, a weighting function may be applied to the input<br />
L4A.0060<br />
values according to the degree of coverage of the output grid cell and according to the SSES.<br />
84 Rule 4.1c WP4-041 The SSES value for a re-gridded data set will take the value associated with the Proximity_Confidence value assigned by<br />
L4A.0060<br />
Rule 4.1a.<br />
84 WP4-042 When pixels in the input data stream are much larger than those of the SSTFND output grid (e.g., microwave instruments),<br />
L4A.0060<br />
as illustrated in Figure 4.1.2, the output grid cell takes the value and confidence data record of the input pixel in which it<br />
