TRMM-LBA/Brazil Instrumentation

A series of three maps are shown below. The first map is a road map with geographical features in the Rondonia area of Brazil for reference. The approximate locations of the radars, profiler, rain gauge networks, and direction finder (DF) are indicated (S=S-pol. radar, T=TOGA radar, #1=Profiler/gauge network 1, black boxes = gauge networks, * = DF). For more information on the rain gauge network, refer to the TRMM-LBA Implementation plan at the NASA Ames Project Office, or an original draft of the rain gauge plan on this site.

MAP #1)

The next map (MAP #2) is an illustration of the instrument layout relative to cities seen on MAP #1. The locations of each platform are indicated according to the legend following MAP #2. In addition to the information given in MAP #1, we have highlighted range rings at 50 and 100 km from each respective radar. Also, the dual-Doppler lobes (as defined by a 30 degree beam crossing angle) are shown.

A more complete table is available.

The last map (Map#3) is based on a Landsat image originally published in Calvet et al. (1995). It shows the location of primary instrument platforms including the dual-Doppler lobes and an approximate triangle over which heat and moisture budgets may be computed using rawinsonde data.
