I would like to calculate summary statistics of rainfall based on year and month. I have the data in a text file (although could put in any format if it helps) extending over approx 40 years: YEAR MONTH MeanRain 1972 Jan 12.7083199 1972 Feb 14.17007142 1972 Mar 14.5659302 1972 Apr 1.508517302 1972 May 2.780009889 1972 Jun 1.609619287 1972 Jul 0.138150181 1972 Aug 0.214346148 1972 Sep 1.322102228
I would like to be able to calculate the total rain annually: YEAR Annualrainfall 1972 400 1973 300 1974 350 .... 2011 400 and also the monthly mean rainfall for all years: YEAR MonthlyMeanRain Jan 13 Feb 15 Mar 8 ..... Dec 13 Is this something I can easily do? I have started by simply importing the text file but data is not represented as time so that is probably my first problem and then I am not sure how to group them by month/year. textfile=r"textfile.txt" f=np.genfromtxt(textfile,skip_header=1) Any feedback will be greatly appreciated.
