  • Meteorological normalisation and non-parametric smoothing for quality assessment and trend analysis of tropospheric ozone data

    Despite extensive efforts to ensure that sampling and installation and maintenance of instruments are as efficient as possible when monitoring air pollution data, there is still an indisputable need for statistical post processing (quality assessment). We examined data on tropospheric ozone and found that meteorological normalisation can reveal (i) errors that have not been eliminated by ...

  • Table of Statistical Corrections According to Feller for the BioCapt® Microbial Impactor in Microbial Air Sampling

    Abstract This application note uses the principle that, as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. The values within Tables 1 and 2 are shown at flow rates of 25–50 LPM and 100 LPM. BioCapt microbial impactors are used on all Particle ...

  • Air Flow Meters to Measure Air Velocity and Air Pressure

    Air flow meters are used to measure air velocity and air pressure. Depending on the type of application, air flow meters are made as hot-wire air flow meters or pocket weather flow meters, both of which can measure air velocity and air pressure. The results of measuring the air velocity can be stored in the memory of the device depending on the model. There are even data loggers for air velocity ...
