The whole country is getting drenched in rainwater including West Bengal. Penguin Tank advises you to measure rainfall at your home simply by yourself. Rainfall is measured using an instrument called rain gauge. It measures rainfall in meters per square meter which is equivalent to mm and can be converted in cm or meter. There are two main steps involved in the process of measuring rainfall.
1. Setting up the gauge : Get a clear cylindrical container made of either glass or plastic and minimum 12 inches tall. Place some pebbles or marbles at the bottom(one inch) of the container to keep it steady. Fill the water to provide it a level starting point for the scale. Inscribe a scale upon the container with the help of a ruler or a measuring tape and a waterproof marker. The scale 0 should be marked just at the water level. Your gauge is ready. Now place it under the open sky on a level ground. Make sure that there are no obstructions such as uneven ground, trees or leaves above the gauge.
2. Measuring Rainfall : Check your gauge every day to determine how much rain has fallen in the last 24 hours. Read the gauge from the bottom, waterline being at the eye level. Mark the amount of rainfall on a graph or a chart. Prepare a chart and mark it on a daily basis. After every recording of the rainfall, empty the rain gauge to get an accurate reading the next day. After recording the data for a month, its time to do the analysis. Sum up the rainfall of all seven days in a week and divide it by 7. You will get the average rainfall for that week. Using the same formula, you can get the rainfall measurement for a week, month or a year.
