Title: Measuring Rainfall
Authors: Balasubramanian, K.V.
Issue Date: Jul-2010
Publisher: CSIR
Abstract: Measuring rainfall forms a very important input for the economic planning of the country. But there is a whole lot of scientific work and periodic maintenance that goes into making this activity a reality. When the first showers of the monsoon give respite from the sweltering heat, the first thing you do is smell the earthy flavour wafting through to your nose. You might also want to catch a few drops on your palm or perhaps get drenched in the pouring rain. But why would someone want to measure the rainfall? Is it important? Well, the oceans hold 97% of the earth’s water (which is saline), while 2% is available frozen in ice caps.  Deep ground water accounts for 0.31%.  The remaining 0.69% of water is only available for the humanity.  The main source of this small amount of water is precipitation in the form of rain or snow. So, measurement of this precipitation (rainfall/snowfall) becomes absolutely necessary since it forms a very important input for the economic planning of a country.
