Virtual-Temperature Profile by RASS Observation

Below is a virtual temperature profile obtained through RASS observation. Some problems remain in terms of data processing, but we expect the error to be less than 1° (i.e., approximately 0.5°) when this processing is performed properly. Further, if the observation parameters are specifically selected to suit the given observation conditions, the observable altitude range should also increase.
