Objectives: In this paper, tuple time-stamping temporal model is proposed for the retrieval of meteorological data. Methods/ Statistical Analysis: This paper accentuate upon the retrieval of temporal database by extending the functionality of Postgres database system. The tuple time-stamping approach is used to query the time-varying data. Conventional databases are not capable of managing temporal data as it is a series of snapshot relations. Findings: We proposed and implemented a temporal model for the retrieval of temporal data using the meteorological dataset of a particular location in the National Capital Region of Delhi for the year 2014.The results may be used for the analysis of climate trends. Applications/Improvement: Various temporal models have been proposed and implemented by the researchers but fewer efforts have been put in the real world problems.
