Current institute names:

My suggestion would be to unify them like this:

 hgf_centers:
-    - "KIT"
+    - Karlsruhe Institute of Technology (KIT)
 
 hgf_centers:
-    - Helmholtz Centre For Ocean Research (GEOMAR)
+    - Helmholtz Centre for Ocean Research Kiel (GEOMAR)

 hgf_centers:
-    - "GFZ, AWI, DLR"
+    - Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences
+    - Alfred Wegener Institute for Polar and Marine Research (AWI)
+    - German Aerospace Center (DLR)

 hgf_centers:
-    - AWI Bremerhaven
+    - Alfred Wegener Institute for Polar and Marine Research (AWI)

 hgf_centers:
-    - GFZ Potsdam
+    - Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences

 hgf_centers:
-    - AWI Bremerhaven
+    - Alfred Wegener Institute for Polar and Marine Research (AWI)

 hgf_centers:
-    - HZDR
+    - Helmholtz-Zentrum Dresden-Rossendorf (HZDR)
