NPOL constitutes a unique and valuable resource for both NASA Earth
Sciences and external communities. The new antenna system provides
better than 1 deg beam width and electrical performance consistent with the
collection of research-quality polarimetric data. In addition to the
antenna system upgrade, the radar signal processor has also been
upgraded to the SIGMET/Vaisala RVP-900 from its original SIGMET RVP-7
technology. The new processor provides a more robust means to collect
and process raw I/Q and moment data in both conventional alternating
(full covariance matrix) and simultaneous transmit/receive modes.
Importantly, the NPOL radar will function as one of only two deployable,
research-grade S-band dual-polarimetric radars in the world. As the
centerpiece of a robust Precipitation Science program, NASA should be
leading the way in innovative and pioneering uses of such a platform
because research grade radars provide the link between what satellites
see and precipitation hitting the ground.
