Query: On the potential for reconstructing the moisture field using commercial
  microwave network data   The atmospheric greenhouse effect and the hydrological cycle of Earth are key
components enabling the planet to support life. Water vapor is a central
element in both of these, accounting for approximately half of the present day
greenhouse effect, and comprising the most important gaseous source of
atmospheric infrared opacity. Specifically, it functions as the fuel for the
development of convective storm clouds. This parameter, however, is considered
one of the least studied due to the limitations of conventional monitoring
instruments. The current predominate monitoring tools are humidity gauges and
satellites which suffer from a lack of spatial representativeness and
difficulties in measuring at ground level altitudes, respectively. This study
demonstrates for the first time the potential to reconstruct the 2-Dimensional
humidity field using commercial microwave links which form the infrastructure
for data transmission in cellular networks. Water vapor attenuates the waves
transmitted by the system and thus these microwave links can potentially form
as a virtual network for monitoring the humidity field. The results show a
correlation of between 0.6 and 0.92 with root mean square differences ranging
from 1.9 to 4.15 gr/m^3 between conventional humidity gauges and the humidity
estimates calculated for the same points in space by the proposed technology.
The results obtained are the first to point out the improved performance of
humidity measurements when using data from multiple microwave links. These
results indicate the tremendous potential of this novel approach for improving
the initialization of meteorological forecasting models thus potentially
improving the ability to cope with the dangers associated with extreme weather.
