3. Introduction This project builds on the successful operational implementation of the Blended TPW in March 2009 Two products are to be implemented in FY09: Blended Rain Rate product Adding MIRS products, especially SSMIS products, to the Blended TPW product All products are implemented in DPEAS, which was ported to the IBM system in FY08 3

4. Project Requirements SPSRB #0708-0023, POES-GOES Blended Hydrometeorological Products; SPSRB #9902-19: POES/DMSP Blended Products. Generate operational blended TPW and RR products from POES, MetOP, DMSP, GOES and GPS. Others: (1) NWS AWIPS OB9; (2) NOAA's Hydrometeorological Testbed (HMT); (3) NOAA's Scientific Data Stewardship (SDS) program. User Community NWS WR, NWS SPC, NWS NHC, NWS HPC, NWS WFOs (AWIPS) NESDIS/SAB NOAA Mission Goals Supported Weather and Water, Ecosystems, Climate Commerce and Transportation Goal Wide – Satellite Services; Polar satellites acquisitions Mission Priority: Mission Critical/High- cannot meet operational mission objectives without this requirement. 4

5. Algorithm Review Enhanced Blended TPW product: MIRS retrievals added Surface type added to algorithm to separate land and ocean TPW blending algorithms. 5

7. 7 Enhanced Blended TPW—Close UP 15 Jan 2010 1705 UTC DMSP F16 MIRS DMSP F16 SSMIS TPW successfully blended!

8. Algorithm Review Enhanced Blended TPW product: MIRS retrievals added Surface type added to algorithm to separate land and ocean TPW blending algorithms. Blended Rain Rate product: Blending algorithm developed (see following slides) Test operation implemented at CIRA http://cat.cira.colostate.edu http://cat.cira.colostate.edu Blends RR data from NOAA 15, 16, 17, 18, and MetOp-A (does not use MIRS RR because of lower resolution, does not use NOAA 19 RR because of MHS problems). 8

9. 5-Day Histograms (of raining pixels) OCEAN“LAND” PDF 0.0 1.0 0.0 PDF 0.25 SSM/I AMSU-B MHS 024681002468 Rain Rate (mm/hr) 0.25 mm/hr bins SSM/I shows expected “lognormal” distribution, but AMSU-B and MHS do not Over “land” all PDFs are similar 9

10. Cumulative PDF 0246810 Rain Rate (mm/hr) OCEAN CPDF 0.0 1.0 Input RR Corrected RR Interpolate CPDFs to correct RR 10

11. The RR Blending Algorithm No correction over land (=“not ocean”) No correction for SSM/I For AMSU-B and MHS over ocean No correction for RR > 5 mm/hr Only negative corrections allowed All scan positions treated the same DMSP F13 SSM/I is the “reference satellite” DMSP F13 histograms were captured before its failure Linearly interpolate the CPDFs to get correction 11

12. Before All AMSU-B or MHS Note lack of rain rates below 0.5 mm/hr Too much blue and green 12

13. After AMSU-B or MHS SSM/I AMSU-B and MHS look a lot more like SSM/I than they would have without correction 13

35. Risks and Actions The new DPEAS code has not yet been implemented at OSDPD However, the code runs in real-time at CIRA, and Last year all of DPEAS was ported to OSDPD, this year only a few modules need to be ported, which should be easy. 35
