Any body knows how to estimte /calculate echo top height from IMD indian S BAND doppler radar data, i tried with modified ETH algorithm proposed by [Lakshmanan et al. (2013)](https://journals.ametsoc.org/view/journals/wefo/28/2/waf-d-12-00084_1.xml) with 5 years of radar data to calculate mean cloud top height vs distribution(counts). Below 10km the cth couts are very low .
