<br>
New research suggests mobile 3G masts offer a cheap
and accurate <br>
weather monitoring network.<br>
<br>
The data, published today in the journal Science, was collected by
an <br>
Israeli team headed by University of Tel-Aviv professor Hagit <br>
Messer-Yaron.<br>
<br>
Rain, snow, humidity, and other atmospheric conditions affect the <br>
strength of electromagnetic signals. Mobile phone operators
already <br>
collect such data and use the knowledge to boost the network when <br>
things turn nasty.<br>
<br>
The team collated mast strength numbers with recorded
precipitation <br>
levels. They found that the variation in reception was a better <br>
real-time indicator of conditions than current radar techniques.<br>
<br>
Thanks to the near-ubiquity of cellular networks, mobile mast <br>
monitoring is also more widely available, and cheaper than
expensive <br>
surface rain gauges, they say.<br>
<br>
The plan now is to up the accuracy even further by taking the
affect <br>
of users' usage of the network on the signal into account.</span></font><font
