Abstract: Based on the 2755 days’ (2001-05-15~2008-12-31) density data derived from CHAMP accelerometer, the model errors of JB2008 and MSISE-00 are analyzed. It is found that the two modes both overestimate the atmospheric density, but the JB2008 is better than the MSISE-00, their average bias is 2.2% and 17.6% respectively. To brief classification of space environment, the model characteristics of latitudes and local time are analyzed in each class space environment. It is found that MSISE-00 model has better local time characteristic and JB2008 has good latitude characteristics. This study has certain significance to master model error characteristics and to improve atmospheric density model.
