    • Abstract
  • This paper presentes a new series of high-resolution earth's gravity field models DQM2000 computed by the method of regional integral correct ion with frequency weight and their accuracy comparison.Based on the OSU91A and EGM96 models and the regional mean gravity anomalies of 20'×20',15'×15',10'×10' and 5'×5'in China,the improved models DQM2000A,DQM2000B,DQM2000C and DQM2000D,whose complete degrees and orders are up to 540,720,1 080 and 2 160 respectively,are developed.
