Temperature reference sensor(MTR-08) is sonde with a fine tungsten wire (10 um diameter) for temperature measurement.
The response is 5/1000sec on surface and 40/1000sec at around 30km altitude. The response is 40times faster than conventional radiosonde.
The fine wire has the aluminum coating and the heating by solar radiation at 30km altitude is less than 0.5k. A reliable temperature data can be acquired.
Features
Temperature sensor with world’s fastest response time for Upper-air observation.
MTR is suitable for researches of a fine structure in boundary layer, turbulence, and observation in stratosphere, where a response of operational radiosonde is slow.
High response and aluminum coating decrease the influence by solar radiation. It enables to acquire reliable data.
To avoid error by self-contamination from the sonde package, it has the long sensor probe and the independent sensor rig.
