Improved Technique for Retrieval of Temperature and Humidity from Neutral Atmospheric Refractivity Profiles

This paper discusses some improvements to a technique for retrieving temperature and humidity from neutral atmospheric refractivities. A technique previously developed used auxiliary information in the form of surface temperature and pressure along with neutral atmospheric refractivity profiles in the troposphere to retrieve temperature and humidity profiles. The height at which water vapor is presumed to be negligible was based on criteria that most of the times it was around ~ 10 km altitude. A new set of criteria are developed wherein it is shown that it is possible to bring this height further down whenever troposphere is dry at altitudes below&nbsp
