R95PTOT- Total annual rainfall on heavy rain days • Identify the ‘heavy’ rainfall days in the future • Sum the rainfall that falls on those days to give average per year. 12.7 mm 2070 2100
Calculating Indices with CDO To calculate some of these indices with CDO for whole model fields we can either use CDO defined extremes operators, or our own. For the percentage of warm days: cdo eca_tg90p ifile1 ifile2 ofile cdo timsum –gt ifile1 ifile2 ofile cdo mulc,100 –divc,[days] ofile ofile.percent Some of the CDO extremes operators are not always robust with PRECIS data, but we can calculate them by using other CDO operators together.
