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 microwave radiometer is used and the frequency is slightly shifted to `see` further in the atmosphere. A consequence of this is that the altitude resolution and the temperature accuracy are not quite as good as the MTP-5H and there is some reduction in accuracy in heavy rain or fog.

MTP 5-PE (Polar Extended range) uses a similar microwave radiometer to the MTP-5HE. However, it is designed to provide much improved altitude resolution, down to 10 m in the first 100 m range. This is important for measurements over snow and ice, where temperature gradients can be very steep over small height increments. Similar effects can be observed over desert surfaces.
