Estimating the availability of sunshine using data mining techniques

The daily temperature values of a city or place acts as data for prediction of rainfall, energy calculation etc. There are weather stations available which records the weather of almost all the region in the earth. The weather data acquired in these stations are raw data and found in abundance. The data mining techniques can be applied to these raw data to acquire meaningful patterns out of it, which can be used to predict rainfall, solar energy availability etc. This paper deals with estimating the temperature values of four cities in Tamil Nadu, South India namely Chennai, Coimbatore, Madurai and Kanyakumari. The paper also illustrates the use of data mining technique- Clustering algorithms Simple k-Means and Expectation Maximization algorithm to compare the availability of sun shine in the above mentioned cities, this facilitates for estimation of solar energy to be acquired in these cities.
