    Absolute gravimeters have significant application in many researches,in order to verify and evaluate the measurement function and performance of cold atom interferometry absolute gravimeter in field scenarios. This paper constructs a test scheme of complex field environments with multiple areas and conditions,focusing on analyzing the influence of temperature,humidity,and elevation changes on the gravimeter’s measurement precision. The experimental results show that the evaluated gravimeter exhibits high measurement accuracy in typical special environments such as high temperature,low temperature,high humidity,and high altitude. The deviation from the reference value is better than 20 μGal,and the mean square error is better than 11 μGal,which can meet the current requirements of most field measurement and mapping. It provides an experimental method for carrying out the gravimeters’ evaluation in field scene,an idea for the further development of atom interferometry gravimeters,and the support for its practical application.
