Meteorology - Predicting the Unpredictable
Weather and Climate Research Systems
Campbell Scientific Inc. weather stations are based around a programmable datalogger that measures the sensors, then processes, stores, and transmits the data. Our dataloggers have wide operating temperature ranges, on-board instructions, programmable execution intervals, and ample input channels for commonly used sensors. Wind vector, wet bulb, histogram, and sample on maxima or minima are standard in the datalogger instruction sets. Most sensors can be measured directly—without external signal conditioning.
Data are typically viewed and stored in the units of your choice (e.g., wind speed in mph, m/s, knots). Measurement rates and data recording intervals are independently programmable, allowing calculation of 15-minute, hourly, and daily data values from 1-minute or 1-second measurements, for example. Conditional outputs, such as rainfall intensity and wind gusts, can also be recorded. The program can be modified at any time to accommodate different sensor configurations or new data processing requirements. If needed, channel capacity can be expanded using multiplexers, including a model designed specifically for thermocouples.
Typical sensors used on our stations include, but are not limited to:
1. Wind speed and direction
2. Solar radiation
3. Temperature (air, water, soil)
4. Relative humidity
6. Snow depth
7. Barometric pressure
8. Soil moisture
Data Loggers and Data Acquisition System
Dataloggers, which may also be referred to as Measurement and Control Units (Systems) or Microloggers, are the heart of a data acquisition system. They measure sensors at a specific scan rate, process data, store the data, and initiate telecommunication. Our dataloggers also have control capabilities allowing them to respond to specific site conditions by opening flood gates, turning fans off/on, etc.
We offer wide range of sensors which are generally designed for long-term installation under adverse environmental conditions. Sensors used in industrial applications such as strain gages, accelerometers, hydraulic pressure transducers, are also available. We have a long chain of sensors for example: Air Temperature Sensors, Air Temperature & Relative Humidity, Barometric Pressure Sensors, Basic Weather Conductivity Sensors,Digital Camera, Dissolved Oxygen Sensors, Distance Sensors, Duff Moisture Sensors, Electric Field Sensors, ph, Dissolve oxygen, precipitation etc.
Automatic Weather Stations
Onset’s research-grade data-logging weather stations are known for performing reliably in the field year after year. These systems offer rugged, weatherproof protection from the elements, and are available in both USB and web-based versions. HOBO weather stations can be configured with any combination of plug-and-play Smart Sensors for measuring air temperature, relative humidity, dew point, rainfall, soil moisture, solar radiation, wind speed and direction, barometric pressure, and more.
Eddy Covariance Stations
The eddy-covariance (EC) technique is widely used to quantify the exchange of heat, carbon dioxide, water vapor, and other trace gases between Earth’s surface and the atmosphere. These data provide the information required to analyze carbon storage properties of various ecosystems, create accurate gas exchange budgets, and compare emissions characteristics between various land use such as agricultural lands, forestlands, sagebrush steppe, or urban plots and landfills.
The EC technique requires the measurement of vertical wind speed and a scalar of interest, such as CO2 or H2O. Ideally these measurements would have low noise and high frequency response, and they would be colocated and synchronized. Wind velocity is typically measured with a three-dimensional ultrasonic anemometer
We offer is a turn-key, closed-path eddy-covariance (EC) flux system for long-term monitoring of atmosphere-biosphere exchanges of carbon dioxide, water vapor, heat, and momentum. A complete system consists of a closed-path gas analyzer (EC155), sonic anemometer (CSAT3A), datalogger (CR3000), and sample pump.
Glacier Monitoring Stations
Glacier Monitoring stations are being acquired by the PRAA as part of the project’s goal to generate knowledge about glacial retreat and high mountain hydrology. The main objective of the station installations is to monitor the behavior of glaciers through radiation and temperature data to determine how much life is left in them. It is hoped that this will allow better water resource management in basins that depend mainly on the melting of glaciers as support for their economy.
Considering the uncertainties of climate change, it is difficult to calculate models of the glaciers’ life span by just watching them. So the need arose to install meteorological stations on the glaciers themselves, in an area that would best represent the glaciers’ behavior and condition.
Solar Monitoring Stations
A solar monitoring station includes a set of instruments to measure the different components of solar radiation that are of importance to solar energy production; global horizontal irradiance (GHI), direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI).
Good quality, reliable radiation data is extremely important for all activities in the solar energy sector. Real-time accurately measured irradiance helps to monitor the system performance. A solar monitoring station is often deployed to evaluate a possible site location for investors to verify the bankability of the installation. It provides input for technology research, quality control, system type selection, maintenance scheduling, operating efficiency monitoring and output forecasting.
Wind monitoring Stations
We offer typically extra ordinary wind monitoring stations because Home weather stations are just not good enough because they record average wind speed. As wind turbines generate power according to the CUBE of the wind speed, short periods of high wind will generate much more power than long periods of low wind - even though both may show the same AVERAGE wind speed.
Agriculture Research Systems
We provide professional- and research-grade measurement systems for many applications within agriculture and plant-related markets. Our systems measure environmental parameters related to evapotranspiration, plant growth and development, and disease modeling. This data is useful for scheduling planting, irrigation, and harvesting; supporting automated weather alerts; and timing for pesticide applications.
Micrometeorologists study surface-atmosphere exchange at time scales ranging from fractions of seconds through inter-annual and spatial scales on the order of 100-1000’s of meters. it focuses on the transfers of greenhouse gases, water and heat driven by near-surface turbulent exchange from a variety of natural and human-influenced ecosystems.
Meatech Solutions offers a best range of micrometeological sensors and systems for measuring greenhouse gas and energy fluxes.
Meatech Solutions builds systems for unattended, long-term monitoring of water quality in many natural and industrial environments, including streams, watersheds, wells, caves, water/wastewater treatment plants, aquaculture operations, landfills, and processing plants. Our systems include Campbell dataloggers, and a huge variety of sensors and communication peripherals, customized for each application.

They are used in many environments, including wells, dams, streams, weirs, storm-water systems, and water or waste-water treatment plants. They are reliable regardless of salinity level, pollution level, or other harsh environmental conditions.
Campbell systems can communicate on licensed-frequency radio, IP cell modems, spread-spectrum radio, GPRS modem and other methods.
Disaster early warning systems today are either not available or extremely ineffective. The Disaster warning system is for protecting lives and property from the damaging effects of both natural and manmade disasters. It provides real time early warning alerts in advance of the impact of disasters and hazards such as tornadoes, lightning storms, tsunami, floods, wild fires and earthquakes. It can also be given for industrial, chemical, and biological accidents, as well as intentional terrorist actions. Most potential threats to human life and property will be included in the system.
We offer a variety of systems in Disaster Warning
• Flood Warning (ALERT)
• Tsunami Warning
