Want data on temperature and irrigated area in the Chennai basin for research on climate change and its impacts on surface water


This mail is for the indiawaterportal team. I am currently researching on climate change and its impacts on surface water resources for Chennai basin that covers the districts of Kancheepuram, Tiruvallur, Vellore and Chennai.

I am urgently in need of the following data : (i) Daily temperature data for 1997-2000, 2011-2012 ; (ii) Irrigated area for crops grown in the basin in the period 1997-2005; (iii) Leaf area index data for crops in basin. Could you please help with any or all of the data.

Thank you

2. Need daily temp data of 2012

I need daily temperature data for the year 2012 for research.

1. Met data tool for daily temperature data

Dear Usha,

For the daily temp data part you can use the Met data tool we have here. Please click on the following link to go to the tool -

You will be able to get district wise data for the various states (for the period between 1901 and 2002).

For the monthly rainfall data, all you have to do is, select the state and district and enter the 'from ' and 'to' years. The data type would be 'precipitation' in your case. Now, when you click on the 'Generate monthly mean for each year' you will get the monthly data for the district for the period mentioned as well as a corresponding graph.
