Data analysis
Added by Khumo Monaka over 5 years ago
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.

Hi Khumo,
without the data I would guess there is less precipitation. Take a look a the single files to get more information about the data values. If you need more help upload some data

Hi Khumo,
the data values are correct after merging the files using the operator mergetime
cdo -O mergetime Southern_Africa_*.nc STS_merged.nc
I've plotted the variable pr of the file Southern_Africa_STS.2015090100.nc 1st time step and the 32nd time step of the merged file and it looks good to me.
