Presentation Transcript

  1. Eliminate Bulk SST in IDPS SST EDR

  2. Suggested EDR Modifications • Delete the bulk SST field • Delete the bulk SST quality flags • Add/update metadata • Add a skin-to-bulk offset value • Remove bulk SST items in N_Quality_Summary_Names/Values • Add reference SST field

  3. Current SST EDR Content • Table 5.5.1.2.1-1, VIIRS Sea Surface Temperature EDR Data Content Summary, from CDFCB, Vol. IV

  4. Suggested SST EDR Content *RefSST is the granulated ancillary NCEP skin temperature (spatially and temporally interpolated)

  5. Bulk SST Quality Flags • These quality flags deleted • Bulk SST Quality (bits 2-3 of QF1_VIIRSSSTEDR) • Bulk SST outside of validation range (bit 7 of QF3_VIIRSSSTEDR) • Bulk SST Degraded (bit 1 of QF4_VIIRSSSTEDR)

  6. Metadata (1 of 2) • N_Quality_Summary_Names • Current content: • Bulk Sea Surface Temperature EDR Summary Quality • Bulk Summary Range Check • Degradation Summary - Bulk Sea Surface Temperature • Degradation Summary - Skin Sea Surface Temperature • Exclusion Summary - Bulk Sea Surface Temperature • Exclusion Summary - Skin Sea Surface Temperature • Skin Sea Surface Temperature EDR Summary Quality • Skin Summary Range Check • Updated content: • Degradation Summary - Skin Sea Surface Temperature • Exclusion Summary - Skin Sea Surface Temperature • Skin Sea Surface Temperature EDR Summary Quality • Skin Summary Range Check

  7. Metadata (2 of 2) • N_Quality_Summary_Values • One-to-one correspondence with N_Quality_Summary_Names • Reduced from 8 values to 4 values • New “skin-to-bulk SST offset” • Skin SST + this offset = bulk SST • Value: 0.17 • Location: Product Granule Group (i.e., VIIRS-SST-EDR_Gran_x)

  8. Documentation • SST EDR Algorithm Theoretical Basis Document (ATBD) • SST EDR Operational Algorithm Description (OAD) Document • Common Data Format Control Book (CDFCB) • Vol. IV, Part 3, Section 5.5.1 – SST EDR • Vol. VI, Appendix C – Data Quality Test Table (DQTT) quality flag mapping • JPSS EDR Production Report for NPP • Section 4.4.1 (requirement NPP.EDR.4.10) • Table 8-2 VIIRS Quality Flags • XML • VIIRS_SST_EDR.xml (XML description of “scaled integer” version of SST EDR) • VIIRS_SST_FEDR.xml (XML description of “float” version of SST EDR) • Requirements? • Other?

  9. Software • Code • ProEdrViirsSST.cpp • sst.cpp • ProEdrViirsSst.h • ViirsSstStructs.h • Files • SST Regression Coefficients Table, i.e., the file VIIRS-SST-Coef-LUT • Data Quality Threshold Table (DQTT), i.e., the file VIIRS-SST-EDR-DQTT-Int • Other?
