  1. Synthesis of work on Budget of Water Vapor and Trace gases in Amazonia Transport and Impacts of Moisture, Aerosols and Trace Gases into and out of the Amazon Region

  2. Budgets CO CO2 CH4 Aerosol Water vapor ... BARCA will also focus on those...

  3. Atmospheric vertical advection Transports by clouds Horizontal advection storage Transports in the Planetary Boundary Layer Surface emission, deposition, absorption

  4. Trace Gas and Aerosol Budgets • Status • 2002 RACC and SMOCC campaigns done but • New features: • Plume rise super parameterization (3 cloud types) • Aerosol deposition • Finish by April 2005

  5. CATT-BRAMS Convective Transport of CO 24-25 Sep 2002 Freitas, Longo et al... 2005 Conv + Resolved Precipitation 40 km resolution GOES Precipitation 4 km resolution mm

  6. CATT-BRAMS Convective Transport of CO21Z 24 Sep 2002 Freitas, Longo et al... 2005 vertical level 11.5 km Vertical section at lat 10S CO (ppb)

  7. CATT-BRAMS Plume of CO (ppb)1100 m sigma-z00Z 27 Aug 2002 40 km grid resolution 200 km grid resolution South America and Africa

  8. Heat and Water Budget:need new LBA regional reanalysis

  9. 850 mb Anomaly Moisture Flux

  10. 15 deg S Vertical Cross section of Meridional Moisture Flux Andes Andes

  11. 17th SSC Recomendation #6 • The SSC recommends that a daily climatology data set (gridded reanalysis) for the Amazon region should be organized by LBA specialists in the meteorology of South America, expressly for the purpose of input to land surface simulation models over the period starting in 2000 to the present (minus ca. 6 months). Required daily variables include mean, minimum and maximum air surface temperature, precipitation amount, mean solar radiation flux (downward shortwave), mean relative humidity, mean wind speed. The spatial resolution of the data set should be the highest possible under current observational and computational constraints.

  12. Regional Reanalysis 2000/2004 Settings: Regional Physical Statisttical Assimilation Systema RPSAS, v. 2003; Regional ETA model, 40 km, 38 levels, Boundary conditions from Global NCEP (6 hrs) , weekly SST • Products: • Reanalysis of state variables (lat, lon, p, T, RU, u,v,w) 40km, 19 levels every 6 hr. • 3 hourly outputs, up to 36 hours for 00Z e 12Z and up tp 12 hours for 06Z and 18Z;

  13. - Linux Server: Pentium IV dual core 3.2 GHz, 1 Gb Ram, 1Tb de disco ; • Supercomputer NEC SX6: 10 proc. , 20 Gb RAM • CPTEC Data Assimilation Group (Aravéquia and Herdies plus 5 technicians) • Processing time : • 17 minutes / Analysis • 10 minutes / Forecast (36hrs) Regional Reanalysis 2000/2004 Storage Analysis : 135 Gb; Boundary conditions : 155 Gb; Regional reanalysis (post-processed) : 110 Gb / year = 550 Gb (2000-2004); Observations : 78 Gb (Source GMAO/NASA: GTS, ATOVS, QuikScat, TPW)

  14. Regional Reanalysis 2000/2004 • Procedure: • Separate periods of 1 year each • 1 month redundancy for continuity • Status: • Running for 2000, 2001, 2002, 2003 e 2004:

  15. Observation Status: • Assimilating between 2500 and 7500 obs/observ. time Upper Air Data: radiosson and satellite

  16. Regional Reanalysis 2000/2004 • Version 1 – operational data • Version 2 – add experimental data
