Abstract

Several assimilation-forecast experiments were performed in which aspects of radiosonde processing or usage were changed: 1. Making observation uncertainty a function of radiosonde type, 2. Removing the assimilation of upper-tropospheric radiosonde humidity, 3. Adding/subtracting an artificial 0.5K bias to radiosonde temperatures
