TECH SAVVY: The weather bulletin on the Tamil Nadu Agriculture University’s website.
COIMBATORE: An agricultural weather bulletin of the Tamil Nadu Agriculture University will now be available on the net. The university has dedicated the web page containing forecast for farmers, Vice-Chancellor C. Ramasamy said, launching the web site here on Friday. Produced by the University’s Agro Climate Research Centre (ACRC), the page can be logged on at http://agmet.tnau.ac.in/acrc/index.html. The centre used the open source weather research and forecasting model’s advanced research weather core for preparing the bulletin. The Meso-scale and Micro-scale Meteorology Division of the National Centre for Atmospheric Research, Boulder, Colorado, U.S., provided the forecast model as an open source to the university. The model was built on two domains with horizontal separate resolutions for the mother domain and a nested domain to improve the accuracy of the forecast. The Global Forecast System of the National Centre for Environment Prediction, in the U.S., was used for developing a four-day forecast cycle on a daily basis. The model was being run on an experimental basis and the results were being verified for accuracy levels. Surface weather parameters such as temperature, wind and relative humidity were available as charts for Tamil Nadu, and updated at 8.30 a.m. and 2.30 p.m. Rain forecast was measured once every 24 hours at 8.30 a.m. Quantitative forecast for all the parameters were provided for the 385 blocks of Tamil Nadu under their districts, with four dates displayed on the charts. A sample forecast would therefore contain the name of the district and the block, central latitude and longitude of the block, maximum and minimum temperature of the day, relative humidity and wind speed at the scheduled timings. The accuracy was expected to improve when it would be possible to use the satellite-linked Automatic Weather Station data to be provided to the university by the Indian Space Research Organisation, and other vegetation data available in the open source from other satellites. This required additional infrastructure and funding over and above what was available from the State Government. The team of R. Jagannathan, Head, ACRC, R. Venkatachalam, Assistant Professor, Information Technology, and K. Seshagiri Rao, Senior Research Fellow, under the leadership of S. Natarajan, Director, Centre for Soil and Crop Management Studies, and the Vice-Chancellor, have brought out the bulletin after a year’s work.
