From single research stations to large networks, Campbell Scientific monitoring systems have become a world-wide standard in cold regions research. Our systems are widely deployed in both high latitude and high altitude applications, anywhere conditions are considered cold, frigid, or uninhabitable. Our stations have measured conditions in the Arctic, sub-Arctic and Antarctic, on continental and alpine glaciers, on the world's great mountain peaks, and in high-altititude airplane and balloon flights.
Long-term, unattended station operation is achieved with low-power use, batteries and solar panels, wireless data retrieval, and large on-board data storage capacity. For example, stations installed in the summer at high latitudes or at high elevations have the capability to monitor conditions while “overwintering.” For all this capability, our dataloggers can be quite small, making them easily transportable in the corner of a backpack.
Cold Regions Research System Benefits
Accurate measurements, durability, low power use, proven reliability, and the ability to customize each station make our equipment ideal for a variety of applications including:
Our monitoring stations are based around a programmable datalogger (typically a CR1000 or CR3000) that measures the sensors, then stores and transmits the data. We designed our dataloggers to provide a high level of station customization. They have programmable execution intervals, operating temperature ranges down to -55°C, on-board instructions for commonly used sensors, and adequate input channels to accommodate many different sensor configurations.
If needed, channel capacity can be expanded using multiplexers, including a model designed specifically for thermocouples. Our dataloggers interface directly to most sensors, eliminating external signal conditioning. Powerful on-board instruction sets allow unattended control decisions based on time or conditional events. For example, peripherals such as heaters or specialized sensors can be actuated based on temperature, wind speed, solar radiation, or some other measured parameter or event. These instruction sets contain programmed algorithms that process measurements and output results in the desired units of measure. Wind vector, wet bulb, histogram, and sample on maxima or minima are all standard to the datalogger instruction sets.
Measurement processing and data storage are programmable, but measurements are typically processed and stored at hourly and daily intervals (e.g., maxima, minima, averages). True averages can be calculated and stored by the dataloggers. Conditional outputs can also be processed and stored. For example, data can be stored at faster intervals based on events such as increased wind speeds or subnormal temperatures.
Almost any sensor can be measured by our dataloggers, allowing stations to be customized for each site. Typical sensors used with our stations include, but are not limited to: relative humidity, solar radiation, wind speed and direction, temperature (air, water, soil), precipitation, snow depth, barometric pressure, soil moisture, and water quality, as well as strain gages, accelerometers, pressure transducers, GPS receivers, linear potentiometers, and many more.
We offer multiple communications options for data retrieval, allowing stations to meet exact needs. Telecommunication options include radio frequency, satellite (Argos, GOES, Inmarsat-C), telephone (landline, voice-synthesized, cellular), short-haul, and multidrop. On-site options include storage module, laptop computer, and datalogger keyboard/display. Robust error-checking and low-power use ensure your data arrives uncorrupted and as scheduled. We can even help you post your data to the Internet.
Our Windows-based software simplifies datalogger programming, data retrieval, and report generation. The datalogger program can be modified at any time to accommodate different sensor configurations or new data processing requirements.
