      In this paper, TRMM Precipitation Radar (PR) products are evaluated by means of simultaneous comparisons with data from the high-altitude ER-2 Doppler Radar (EDOP), as well as ground-based radars. The comparison is aimed primarily at the vertical reflectivity structure, which is of key importance in TRMM rain type classification and latent ...

      In 1993, the DMN achieved the installation of four other Doppler radar and the upgrade of the first Radar installed in 1986. Thus, the national network of Doppler weather radar was achieved. The following figure (figure2) shows the location of the five Radar sites while the following table (table1) shows technical characteristics of each radar.

      A good rule of thumb is that they should be updated once per PRI in a low PRF radar or once per coherent dwell in a pulsed-Doppler radar. The above implementation is feasible if the radar has a digital computer fast enough to compute , and , and apply it via Equation (17). With modern radars that use DSP this may be a feasible approach.

      Petersen et al. (2003) used the Brown’s C-band Doppler radar observations to study the convective structure in the northeast Pacific ITCZ as a function of 3-5 day easterly wave phase. Their work expanded upon more limited radar studies of easterly waves during GATE and TEPPS (e.g., Thompson et al. 1979 and Serra and Houze 2002).
