CMIP5 Global Averager

The  CMIP5 Global Averager computes weighted spatial averages of selected CMIP5 files.
The weights are determined from the grid cell area associated to each grid point of the field.


1. Selecting files


In order to select files from the CMIP5 dataset archive, the user needs to choose values for each one of the boxes bellow.
.

a) Using Input File Paths parameter

For example, you can paste in the following paths:

/badc/cmip5/data/cmip5/output1/IPSL/IPSL-CM5A-LR/1pctCO2/mon/ocean/Omon/r1i1p1/v20120114/pr/pr_Omon_IPSL-CM5A-LR_1pctCO2_r1i1p1_185001-198912.nc
/badc/cmip5/data/cmip5/output1/IPSL/IPSL-CM5A-LR/1pctCO2/day/atmos/day/r1i1p1/latest/pr/pr_day_IPSL-CM5A-LR_1pctCO2_r1i1p1_18500101-19891231.nc

The use of this parameter requires you to know the exact path of the CMIP5 files you want to use.



b) Using Input Job Id parameter

If you paste in the Job Identifier of a previous completed CMIP5 process then the output files of that process will be used here as input files. If you do not know the exact path of the files you want to use or you do not want to use files outputted by a previous process, then the best way to select files is by using the process called Select CMIP5 Files or the process called Select CMIP5 File Group .



c) Using Select CMIP5 Files and Select CMIP5 File Group processes

These processes allow the user to select CMIP5 files from a set of models and ensemble members for a given experiment, variable and time period.
These processes return a webpage.
Use the link "Send to" to send the selected files to any one of the other CMIP5 processes.



d) Using "With File Selection" named processes.

In these processes the user does the selection of files as in c) above and submit the job in the same webpage.

2. Output


By clicking the "Submit" button (not shown in this image) the WPS will run the SelectCMIP5Files process,
which will eventually return a window similar to the one bellow.

An email with the same information is also sent to the user.


3. Using the selected files with other CMIP5 processes


By clicking the "Send to CMIP5Regridder" or the "Send to CMIP5GlobalAverager" link the user will be directed to the webpages of the Regridder or of the Averager process.
In that webpage, the "FileGroupURL" box will be already filled in with the web address of the file containing the paths of the CMIP5 files selected above.
The user may want to copy this web address and use it with any other CMIP5 process.



a) Using Input File Paths parameter

For example, you can paste in the following paths:

/badc/cmip5/data/cmip5/output1/IPSL/IPSL-CM5A-LR/1pctCO2/mon/ocean/Omon/r1i1p1/v20120114/pr/pr_Omon_IPSL-CM5A-LR_1pctCO2_r1i1p1_185001-198912.nc
/badc/cmip5/data/cmip5/output1/IPSL/IPSL-CM5A-LR/1pctCO2/day/atmos/day/r1i1p1/latest/pr/pr_day_IPSL-CM5A-LR_1pctCO2_r1i1p1_18500101-19891231.nc

The use of this parameter requires you to know the exact path of the CMIP5 files you want to use.



b) Using Input Job Id parameter

If you paste in the Job Identifier of a previous completed CMIP5 process then the output files of that process will be used here as input files. If you do not know the exact path of the files you want to use or you do not want to use files outputted by a previous process, then the best way to select files is by using the process called Select CMIP5 Files or the process called Select CMIP5 File Group .
