CDO

Greetings all,

I just successfully ran RegCM4.6.1 now i have outputs and want to perform different statistical analysis to it. My main parameter is Precipitation. I have many outputs (monthly data) with different timesteps.
1. I want to merge all the months from July 2016 to June 2017 and also have 1 timestep.
2. I tried using mergetime, yearsum and timsum commands but i feel they is something I am not doing right because i still get a Map with almost no rainfall.

Kindly assit as to how I can approach this. I have attached a png of how my output looks. Basically i used mergetime to merge months from July 2016 to june 2017, then i used splitname to extract precipitation only, then i used timsum and lastly multiplied with a constant 86400 to get mm/day

I am lost as i have been working on data analysis for over a year without any progress.
