WISENSE MNET: A Low Cost Platform for Microscale Measurements of Atmospheric Variables

Micrometeorology refers to atmospheric processes that have spatial scales on the order of few hundred meters to a kilometer and temporal scales of under 24 hours.  Important phenomena include frontal passages, thunderstorms and pollution dispersion. Measurements of atmospheric variables such as pressure, temperature, humidity and winds when combined with soil characteristics or chemical composition of air can yield important information on conditions in a localized area. It is desirable to have a dense network of measurements to collect real time information that can be analyzed for making useful decisions. Applications for such a dense network of microscale measurements are numerous and we will present a series of case studies in upcoming blog posts.

In a recent article in the bulletin of the American Meteorological Society, Shapiro et al. (2009) describe an observing network deployed by the university of Oklahoma. The primary aim of this network is to provide a hands on experience to students in working with a micormeteorological data network.  The network consists of 28 temperature/humidity loggers spaced about 30 m apart. The data are stored onboard dataloggers at 5 minute intervals. Data retrieval must be performed manually and is reported to take about 3 hours every 6-10 weeks.

The WISENSE MNET platform offers significant improvements to the type of network described above. The wireless MNET is low-cost, easy to deploy and most importantly eliminates manual data transfer. As such, the measurements can be made at much higher temporal resolution and are truly real time and can be immediately analyzed and visualized. Our MNET module can replace the manual data loggers or we can supply integrated measurement systems that contain both the weather/chemical sensor and the wireless platform. Furthermore, adding more sensor stations is a breeze and does not add to the data retrieval effort! The WISENSE MNET can also immediately report malfunctioning stations for quick maintenance.
