Weather variables such as wind speed and direction, air temperature, humidity and rainfall are important factors in determining the course of a wide range of events. For example, agriculture has always been heavily dependent on the weather and weather forecasts, both for its control on the quality and quantity of a harvest and its effect on the farmer’s ability to work the land or to graze his stock.
Water resources generally depend critically not just upon rainfall, but also other weather phenomenon that together drive plant growth, photosynthesis and evaporation. Just as pollen and seed dispersal in the atmosphere are driven almost entirely by the weather, so too is the direction and distance of travel of atmospheric pollution.
Weather monitoring is also important not just in defining present climate, but also for detecting climate change and providing the data to input into models which enable us to predict future changes in our environment.
Because of the wide variety of uses for the information, there are a large number of environmental variables which are of interest to different groups of people. These include solar radiation, wind speed, wind direction, barometric pressure, air temperature, humidity and net radiation.
The demand for these data, usually on an hourly or more frequent timescale, has increasingly been met by the development and widespread deployment of automatic weather stations (AWS’s) over the past 30 years or so.
Automatic Weather Station
EE-WMS-01, the automatic weather station developed by India-based Engineering and Environmental Solutions is a highly sophisticated monitoring & logging of intrinsic weather conditions like temperature, barometric pressure, wind direction, wind speed, wind chill and other optional parameters according to your requirements.
Application areas include agriculture, hydrology, ecology and meteorology. For any sort of customized application, Engineering and Environmental Solutions can give assistance to select the best blend of sensors, data logger and accessories accordingly.
- Field proven in severe weather conditions.
- Unattended weather recording at remote and exposed sites.
- Wide choice of sensors and accessories.
- GSM Modem communication.
Flexibility and Customization
The DL-W’s analog inputs can be fully customized. Each channel can have its own input type and recording parameters. Software gives the user control over reading frequency, thresholds and units, and provides recording options for average, min and max, plus specialized wind options including wind rose, gusts and wind averaging Users can add their own custom sensor types to the sensor library, exploiting the DL-W’s detailed configuration options.
The DL-W provides 4 input ranges down to microvolt resolution with adaptive auto-ranging, excellent analog accuracy, and configurable sensor excitation enabling it to support nearly all analog sensors. Calculations based on the measurements from several input channels can be recorded and displayed as additional virtual channels (calculated measurements).
