![]() ![]() In commercial or industrial weather station applications, wind, temperature, humidity, or other measurements are only one input to management decisions. Consequently, selecting a high-end instruments that provide 0.02 degree resolution may be misguided if this is the principle requirement. Wind is reported using 2 min or 10 min averages and presented in 10 degree increments. If comparative measurements are used, can installation and equipment differences be controlled and are differences understood?įor example, aviation applications do not make flight changes if there is a 1 degree or 2 degree change in the wind direction.Are comparative measurements between stations involved?.What measurement change will affect actionable decisions?.The principle questions affecting the need for precision and accuracy are determined by the application. In contrast, I worked with several professionals that used low-end equipment because they understood where and how a good image was created and the variables involved. These, typically German, cameras claimed exotic capabilities or precision construction and were always owned by amateurs. ![]() Occasionally, we would be asked to repair or comment on an “exclusive” camera. More decimal places does not make better data.Ī number of years ago I worked as a camera repair technician. Research weather stations can produce junk measurements just as effectively as a grocery store instrument. Weather station equipment, like any instrument, is only as good as the installation. So, what is a “Professional Weather Station?” Anyone that does the job it is intended to do. It isn’t hard to find consumer-grade equipment with the “Professional” moniker. Compact cars and 4×4 trucks are optimized for their intended application and within their own unique design constraints.Ī plastic, $40 weather instrument may be just as effective for a specific application as one that costs $25,000. ![]() Engineers must balance design priorities such as precision, cost, ease-of-use, application needs, material characteristics, operating environment, manufacturability, serviceability, and so forth. All tools are designed with particular constraints in mind. ![]()
