ATTEX - Model MTP-5PE -Similar Microwave Radiometer
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.
To achieve this improved resolution a much narrower field-of view of 1° C is required, and the scanner moves in smaller angular steps. A larger capture area is needed in order to maintain the signal-to-noise performance. Therefore, the scanner assembly is larger than for the other models. The radiometer and electronics have additional stabilisation and modifications for operation in typical Polar conditions down to -80° C, as encountered in the Arctic and Antarctic.
