Beskrivelse

The International Standard mainly specifies the requirements in order to perform visual range lidar
measurements for the determination of direction-dependent meteorological optical range (MOR). The term
"visual range lidar" is used in this standard to apply to the lidar systems making the visual range
measurement, commonly also named visibility measurements. Due to physical approximations, the
quantitative determination of the meteorological optical range is limited to 30 m < MOR < 2000 m. For this
purpose, the International Standard specifies the performance of visual range lidar systems utilizing the
method of range-integrated visual range measurements on the basis of light extinction.
Based on the direction-dependent meteorological optical range (MOR) the following parameters can be
calculated:
– horizontal visual range
– vertical visual range
– slant visual range
NOTE – The measures for visibility are strongly related to the historical definitions of visibility, which are related to
human observers. The lidar technique extends the definitions to various conditions as day-light and night-time conditions.
In addition, the measurement principle is capable to retrieve cloud base height, boundary layer depth, fog
banks, aerosol profiles due to the signal attenuation by water vapour and/or aerosols. Examples for these
applications are given in the informative Annex B.
This International Standard can be used for the following application areas:
– meteorological stations
– airports
– harbours
– waterways
– roads and motorways
– automotive
– oil platforms
