  1. EVALUATION OF HIGH RESOLUTION SATELLITE PRODUCTS UNDER COMPLEX PRECIPITATION REGIMES Augusto J. Pereira Filho1 Phillip Arkin2 Joe Turk3 Ricardo Hallak1 Felipe Vemado1 Cesar Beneti4 1DAC/IAG, University of São Paulo, Brazil 2ESSIC, University of Maryland, College Park, USA 3NRL, Marine Meteorology Division, USA 4SIMEPAR, Paraná, Brazil 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  2. Program for the Evaluation of High Resolution Precipitation Products (PEHRPP) coordinated by ESSIC and NRL. Goal is to compare and to validate these high resolution datasets. 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  3. SPWR RAINFALL ESTIMATES X CMORPH, TRMM, PERSIANN and NRL- BLENDED (m) São Paulo, Brazil. 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  4. SPWR DATASETS: 10/2005 TO 03/2006; SATELLITE PRECIPITATION DATA: 0.25 DEGREE X 3-HOUR; SYSTEM TYPES: COLD FRONT, RAIN BANDS, ORDINARY CONVECTION, SQUALL LINES 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  5. EXAMPLES 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  6. COLD FRONT 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  7. RAIN BANDS 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  8. ORDINARY CONVECTION 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  9. OVERALL RESULTS All data sets available 10/05 to 03/06 0,1 mm 0,2 mm 1,0 mm 4,0 mm 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  10. Coordinate discrepancies; Phase and amplitude errors; All four methods yielded poor results; Radar rainfall accumulation higher than satellite ones; Radar data with range effect and other problems; Best performance for low rainfall accumulation: CMORPH; Best performance for higher accumulation: PERSIANN; Fewer data for PERSIANN; All methods are limited; Need for rain gauges and stream gauges verification. CONCLUSION 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia

  11. Work supported by: FAPESP and CNPq (BRAZIL) NCAR and ESSIC (USA) THE END 3rd INTERNATIONAL PRECIPITATION WORKING GROUP WORKSHOP 23-27 October 2006, Melbourne, Australia
