Histogram of an outlier quality test.

This Quality Measurement Experiment (QME) compares the retrieved water vapor and temperature profiles from the VAP MWRPROF with radiosonde profiles. The experiment is designed to help evaluate the skill of the retrieval algorithm used in the VAP MWRPROF. In addition to the retrieval algorithm, this QME provides a check on the measurements made by the ground-based sensors used as input to the retrieval algorithm. This QME also helps to assess the ability of the radiosondes to measure the moisture and temperature in the atmosphere.
