Overview of the Experiment:

TRMM-LBA was carried out in Amazonia from 1 November 1998 to 28 February 1999. The experiment was a major component of the NASA TRMM ground validation program and focussed on the dynamical, microphysical, electrical and diabatic heating characteristics of tropical convection in the Amazon region. Data collected from TRMM-LBA is being used in part to validate products from the TRMM satellite and numerical cloud models. Observational platforms involved in the experiment included the NCAR S-pol radar, the NASA TOGA radar, atmospheric sounding and tethersonde systems, the NASA ER2 and UND Citation aircraft, a lightning location and detection network, raingauges, disdrometers, and NOAA Aeronomy Laboratory UHF and S-band profilers. TRMM/Brazil was conducted in parallel with the wet season component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia.
