MTP-5HE

MTP5HE


microwave radiometer

MTP 5-HE (Extended range) was developed for locations where the urban / industrial area lies in a valley or close to mountains and inversions up to 1000 m can cause problems.


In order to measure to 1000 m a more sensitive and narrower bandwidth design of receiver is used and the frequency is slightly shifted to see further in the atmosphere.


Typically, temperature inversions that cause bad air quality events occur well below 600m, if they are higher than this there is not normally a problem. However, in a valley or close to mountains, higher inversions can trap pollutants over the urban or industrial area.

MTP 5-HE is the extended range version of the MTP-5H and has similar design and features. However, it measures up to 1000 m by using a more sensitive and narrower bandwidth design of receiver with the frequency slightly shifted to see further into the atmosphere. A consequence of this is that the altitude and temperature accuracies are not quite as good as the MTP-5H and there is some further reduction of accuracy in heavy rain or fog.
