Abant Izzet Baysal University, Dept. of Geomatics Engineering, Bolu, Turkey author Yagci, O. Istanbul Technical University (ITU), Turkey author GFZ Data Services publisher ITU_GGC16 is a static global gravity field model up to degree order 280 computed from the combination of ITU_GRACE16 (up to d/o 180) and GO_CONS_GCF_2_TIM_R5 (up to d/o 280) by collaboration of various national institutions (YTU, KOU, NEU, SU) lead by ITU and OSU as the international collaborator with the support of research grant no 113Y155 from the Scientific and Technological Research council of Turkey (TUBITAK). The combination is performed at the normal equation level with variance component estimation. No rate terms were modeled, and no corrections for earthquakes have been applied. For additional details on the background modeling, see the GFZ RL05 processing standards document by Dahle et al. (2013). Complete Akyilmaz, O.
