-We can download a single data file following the instructions as described below:
-
-1. Go to the [CMIP5 search page on the DKRZ ESGF node][cmip5-search]
-2. Perform the following search constraints
-
-    - Model = HadGEM2-ES
-    - Experiment = historical
-    - Time frequency = mon
-    - Ensemble =  r1i1p1
-    - Variable = thetaoga
-
-3. Press search button
-4. On single search result press `List files`
-5. At bottom of page click on `Show All Files`
-6. Find the file which starts with `thetaoga` in the list
-7. Use `HTTP Download` link to download
