Dr.-Ing. Roelof Rietbroek

Roelof Rietbroek is researching sea level change by making use of several satellite techniques. These include radar altimetry, which measure the sea surface height and GRACE gravimetry which measure the gravity field of the field. Roelof also blogs on his personal website and can be found on
