No, I think you are wrong there.
The boots on the ground are the guys that collaborate the doppler info.
Some come has to verify the technology.
Risky bushiness, but God Bless Them, they have saved thousands.
Eh, I just have little tolerance for the fictions that people tell themselves to feel better.
The idea that storm “chasers” have saved thousands is extraordinarily dubious.
The vast majority of tornado warnings are based on radar, and this is even more true of the few EF3+ tornadoes that cause the overwhelming majority of deaths.
The main role chasers play now is preventing false alarms (i.e. if they don’t see a tornado, then the NWS will be less likely to issue a warning based on radar).
Note I’m distinguishing between chasers and spotters.
I submit that if there were no chasers of any kind for the last 20 years, the combination of radar and spotter networks would have resulted in about the same number of deaths prevented.
Again there are VERY few chasers doing legitimate science; a great many dress themselves up in scientific value because they’re too embarassed to admit (and they shouldn’t be) that they are doing it because they like to see tornadoes.
