Weather radar technology improvements in chronological order

[image shows sharp benefit increases beginning with weather radar reflectivity technology in 1957, another sharp rise with implementation in Doppler technology during the 1990s, and another projected rise in this decade with the advent of dual polarization techniques.]

Benefits (on relative scale) from advancements in radar technology. Vertical lines indicate introduction of the technology into the NWS. Benefits prior to introduction are due to better understanding of phenomena, and increase in benefits after introduction is caused by improvements.
