GPS velocity field (MIT 2019.0) for the East African Rift System generated by King et al.

This GPS-derived velocity field for East Africa was generated from continuous (cGPS) and survey-mode (sGPS) data acquired between 1994 and December 2018 and is part of a larger regional velocity field determination (Investigators Robert King, Michael Floyd, Robert Reilinger). The data files are in ASCII text format and were created as part of the collaborative project called A Community Velocity Field for East Africa. They are an updated version of the 2016 solutions that are available at http://dx.doi.org/10.1594/IEDA/321764. Also included is documentation describing the data sources and calculations used in generating the updated velocity field. Funding was provided by NSF grants EAR-1551753 and EAR-1551823.本东非GPS衍生速度场（GPS-derived velocity field）由1994年至2018年12月间采集的连续GPS（continuous GPS, cGPS）与测量模式GPS（survey-mode GPS, sGPS）数据生成，属于更大尺度区域速度场解算工作的组成部分（项目负责人为Robert King、Michael Floyd与Robert Reilinger）。该数据集采用ASCII文本格式，是名为"东非社区速度场（A Community Velocity Field for East Africa）"的协作项目的产出成果之一。本数据集为2016年解算结果的更新版本，2016年解算结果可通过链接http://dx.doi.org/10.1594/IEDA/321764获取。数据集还附带用于说明本次更新速度场生成所用数据来源与计算流程的文档。本项目由美国国家科学基金会（National Science Foundation, NSF）的EAR-1551753与EAR-1551823两项基金资助。
