3 The Brazilian Space Agency AEB

4 The Brazilian Space Agency AEB is an independent institution linked to the Ministry of Science and Technology with the purpose of developing space activities of national interest

5 The Brazilian Space Activities Program - PNAE

6 The Brazilian Space Activities Program - PNAE is established by the AEB to summarize the space activities with an horizon of ten years and is reviewed each two years

7 The current PNAE covers the period

8 The main themes of the PNAE are: - Earth Observation - Scientific and Technological Missions - Meteorology - Access to Space - Telecommunications - Research and development

9 GPM Brazilian Program GPM-Br

10 The GPM Brazilian Program GPM-Br was established by AEB with the aim at coordinating the actions of Brazilian institutions concerning the GPM and encouraging the use of the available data.

11 GPM Br LANDMARKS 2004, MAY: THE BRAZILIAN SPACE AGENCY (AEB) ESTABLISHED THE GPM-BRAZIL (GPM-Br) PROGRAM 2005: THE PNAE COVERING THE ACTIONS IN METEOROLOGY INCLUDES GPM MISSION 2006, FEBRUARY: AEB REQUESTS THE NATIONAL INSTITUTE FOR SPACE RESEARCH (INPE) FOR GPM-Br SPACECRAFT VIABILITY STUDY 2006, OCTOBER: INPE PRESENTS THE PRELIMINARY SPACECRAFT VIABILITY STUDY FOR GPM-Br PAYLOAD 2007, SEPTEMBER: GPM-Br SPACECRAFT DEVELOPMENT IS INCLUDED IN INPE s BUDGET FOR PERIOD

23 > GROUND BASED OBSERVATIONS VALIDATION THE FOLLOWING FIGURE SHOWS THE UPDATED (AS OF NOVEMBER, 2007) BASIC CONFIGURATION OF THE MAIN VALIDATION SITE AS AGREED UPON BY THE CCO, TO CARRY OUT GROUND & AIRBORNE VALIDATION IN THE STATE OF SÂO PAULO. ADDITIONALY IT IS BEING CONSIDERED THE INCLUSION OF RADAR AND LIGHTNING DETECTOR FROM PARANÁ STATE NETWORK > AIRBORNE OBSERVATIONS A PROMISING POSSIBILITY IS THE DEPLOYMENT OF THE NEW RESEARCH AIRCRAFT HALO (TYPICAL FLIGHT LEVEL 18KM), EQUIPED WITH MICROWAVE RADIOMETERS, AND INSTRUMENTED BALLOONS TO PERFORM DEDICATED OBSERVATIONS FOR GPM VALIDATION, IN BRAZIL (SP). SÃO PAULO STATE OPERATIONAL NETWORK AN AGREEMENT IS BEING SOUGHT FOR COOPERATION BETWEEN GPM-Br AND SIHESP (INTEGRATED HYDROMETOROLOGICAL SYSTEM OF THE STATE OF SÃO PAULO), FOR USE OF THE LATTER IN THE VALIDATION EFFORTS (SIHESP IS AN OPERATIONAL SYSTEM PERFORMING RAINFALL MEASUREMENTS AMONG OTHERS THROUGHOUT THE STATE).

24 Main Ground Validation Site

28 SCIENCE AND ALGORITHMS BASIC & APPLIED RESEARCH: RADIATIVE MODELS (INSIGHT INTO ICE SCATTERING) SURFACE MICROWAVE RADIOMETRY CHARACTERIZATION OF THE PRECIPITATION OVER BRAZIL (INCLUDING DROP SIZE DISTRIBUTIONS, HYDROMETEORS DISTRIBUTIONS ALONG THE VERTICAL) STRATIFICATION OF Tb-z RELATIONSHIPS ALGORITHMS: PRECIPITATION ESTIMATES THROUGH COUPLING OF A RADIATIVE TRANSFER MODEL TO A WEATHER FORECASTING MODEL, WITH EXPLICIT CLOUD MICROPHYSICS. PRECIPITATION ESTIMATES THROUGH Tb-Z RELATIONSHIPS STEMMING FROM COMPARISONS OF SAME PROBABILITY LEVELS FOR BOTH VARIABLES

29 Continental Passive Microwave Based Rainfall Estimation Algorithm: Application to the Amazon Basin USProb: Statistical algorithm to estimate rainfall over the Amazon Basin region using the TRMM Microwave Imager (TMI). Distribution similar to GPROF G but without the bi-modal characteristic observed between mm/h.

30 Continental Passive Microwave Based Rainfall Estimation Algorithm: Application to the Amazon Basin High correlation between USProb rain area and volume estimates and PR rain area and volume estimates. Good agreement with both PR and S-POL S rainfall distributions. Biscaro, T. S. and C. A. Morales Journal of Applied Meteorology and Climatology in final revision

31 Intercomparison of Integrated Water Vapor Estimates from Multisensor in the Amazonian Region GPS AERONET Summary GPS/AERONET/HSB HSB RS80 GPS, CIMEL and HSB overestimated humidity when compared with RS 80. CIMEL overestimated IWV when compared with GPS. HSB presents the largest dispersion GPS errors are due to high solar activity and multi-path effect, Has the RS 80 a dryer BIAS?
