A lot of efforts are usually spent on gas concentration measurements and making sure that the measurements are correct. However, all that is of little value if the resulting data is not available. Here is where the instrument interfaces come in play.

We all know how to calculate the average of a set of values: add the individual values and then divide by the number of them. Right? Yes, almost always right, but if you work with air quality and specifically meteorological data, you must sometimes think a little further.

Stratospheric ozone is a blessing. It prevents most of the sun’s ultraviolet radiation from reaching the surface of the earth, and thereby protects surface-dwelling life from damaging UV rays. At the same time, ground-level ozone is a major air pollutant. Let’s take a closer look at the latter phenomenon.

Do you need a gas monitoring system? Then you know which gases you want to monitor, and you probably have an idea of measurement ranges and accuracy requirements. But which other aspects have to be considered?
