One in South Pasadena seemed to be the best WiMax spots back when it was still in deployment. I doubt they're all weather stations, seeing as I don't see the use of having such a dense sensor distribution for tracking weather. I can only guess it'd be for seismic activity (they are working on adding sensors to the seismic detector network), or the possibility they're antennas for some sort of urban wireless network. Whatever they are, they're definitely growing in number. Good to know I'm not the only one to notice them. </p>

<div><div>I was curious too. I looked both at the Weather Underground and NOAA station locator websites and could not find anything listed at those cross streets.<br></div>

<div>Some questions that might lead to more answers:<br></div>
<div>* Is pole on private or public property?<br></div>
<div>* Do you see a control box on the ground? I am guessing the control and communication equipment is mounted above the radiation shield.<br></div>
<div>* Is there a wire going from the station into the pole?</div>
<div> </div>
<div>Maybe its a station for a local school.</div>

<div>They could be monitoring for other stuff. Air pollution but
then they usually need easy access to a particulate filter

There are two of these things mounted on poles one block
apart on Mission and Fair Oaks in South Pasadena. <br></div>
<div> </div>
<div>
What are they? Is the city running some kind of weather
station?<br></div>
