For practical purposes, it could appear very useful to describe the refractivity profile with an analytical expression. Recently, a new equation, developed for radar applications, was successfully used to approximate the refractivity profiles computed by a physical bulk model. In this paper, we extend the analytical formulation to the optical cases dominated by subrefraction situations. Using a ray tracing algorithm and experimental data related to mirage effects, our paper shows that the physical bulk profiles and the fitted analytical ones give very similar results.","PeriodicalId":203781,"journal":{"name":"2018 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133396682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we discuss how GPS signals can be used to estimate the amount of water vapor in the atmosphere. Furthermore, we demonstrate the importance of such precipitable water vapor (PWV) in the atmosphere for the task of rainfall detection. We present a detailed analysis in our dataset of meteorological data of 3 years.
