From 1878 to 1906, Hildebrand-Hildebrandsson was the director of the observatory at the University of Uppsala and a professor at the university. His main works dealt with atmospheric general circulation and the interrelationship of individual centers of action.
Hildebrand-Hildebrandsson carried out cloud observations to study air currents at different altitudes. Together with L. Teis-serenc de Bort, he organized studies of the upper layers of the atmosphere by means of sounding balloons in Denmark and Sweden. Hildebrand-Hildebrandsson was one of the compilers of the International Cloud Atlas (1896), which was the first work of its kind.
