Identification of Non-precipitating Clouds using PWV Analysis

摘要

Background: The objective of this paper is to identify non-precipitating cirrus, cirrostratus, and cirrocumulus clouds by measuring the precipitable water vapor (PWV). Method: PWV is a measure of the liquid water that obtained if all the water vapor in the atmospheric column is condensed and precipitated which calculated from the water vapor channel data obtained from geostationary satellites. In this paper, places with particular non-precipitating clouds are selected and PWV value is calculated. The study is conducted over a period from 1 st January to 31 st December of 2014. Results: The range of PWV values measured is used to identify the high level, non-precipitating clouds. Application: PWV values obtained can be used along with more climatic data for cloud classification
