Fortaleza Campaign
Main Target Study: Warm Clouds and MCSs organized by Easterly Waves
From 21 March to 29 April 2011 – The GPM Planning Meeting and the CEOS –
PC will be held during this period in Fortaleza
Additional Data: Aircraft for microphysical measurements (if the airplane will be OK) and S
and X Band radar.
Belem Campaign
Main Target Study: Tropical Squall Lines and Local Convection
From 30 May to 9 July 2011
Additional Data: S Band Radar
Controlled Meteorological balloons are small
altitude-controlled platforms with bi-directional satellite
communication and long-duration flight capability _ Voss and Fitzgerald collaboration
Belem Squall Lines Climatology : 2000 to 2006
Classification : CCL: Costal Convective Line ( Propagation < 170 km) SL1: Squall Line Type 1 ( 170 Km < Propagation < 400 km) SL2: Squall Line Type 2 ( Propagation > 400 km) SL2 – STM – Moved around Santarem = 56%
São Luiz do Paraitinga Campaign
Main Target Study: Warm Clouds, Cold Fronts, MCSs, SACZ and Local
Convection
From 31 October to 22 December 2011
Additional Data: S Band Radar and “Lightning Mapping Array” (LMA) – NOAA and NASA
– Steve Goodman
LMA - Lightning Mapping Array
o The LMA system:
o locates the peak source of impulsive VHF radio
signals from lightning
o uses unused television channel by measuring the
time-of-arrival of the magnetic peak signals at
different receiving stations in successive 80 ms
intervals
o hundreds of sources per flash can be detected in
space and time (GPS), allowing a three-
dimensional (3-D) lightning map to be constructed
Foz do Iguaçu Campaign
Main Target Study: MCC and Cold Fronts
From 9 November to 13 January 2012
Additional Data: La Plata Basin Campaign
Goal: Measure MCCs to accomplish the GPM and La Plata Basin Regional Hydroclimate
Project (LPB) goals.
Foz do Iguaçu is located on the border of three countries: Brazil, Argentina and Paraguay, where MCSs
produce a large impact. More than the 80% of the precipitation is explained by those systems
Brazil
Argentina
Paraguay
Foz do Iguaçu Campaign
Percentage of surface rain from 2A25 explained by MCSs over La Plata Basin
This experiment will focus on these set of questions:
What are the main surface and boundary layer processes in the formation and maintenance of large and long live MCS?
How cloud microphysics and electrification processes evolves during the cloud life cycle?
What is the contribution of the aerosol in the process of formation of MCC precipitation?
How to improve both space and time precipitation estimation of rainfall over the continent for the GPM constellation over
the region?
How to improve quantitative precipitation forecast over MCS?
How models do represents the evolution of the PBL and the microphysics of these complex convective systems?
The deployment of a dual frequency and
polarization radar like NASA's N-Pol would
contribute with other observations to better
understand the microphysics processes and
their evolution associated with MCS. Also
airplane measurements will be facilitate by
the geographical position.

Cloud-Aerosol-Precipitation Interactions
Aerosol effects on scattered cumulus clouds, especially the
aerosol radiative effect and with a special focus on the impact
of biomass burning aerosols;
Aerosol effects on deep convective clouds, precipitation, and
lightning under different aerosol and synoptic regimes,
including the roles of aerosols in changing regional climate and
atmospheric circulation; and
Improvement on parameterizations of aerosol-cloud
interactions in the climate models
