摘要
•We describe the first attempt to measure Jupiter's zonal winds with Doppler imaging spectroscopy in the visible domain•Observations were performed with a new concept of imaging spectrograph dedicated to measuring atmospheric dynamics•Zonal wind profiles of Jupiter, obtained in 2015 and 2016, are compared with wind profiles from cloud-tacking observations•Both profiles are compatible with the cloud-tracking, except in a small band at the north of the equatorial belt•We show that Doppler velocities can be measured with sufficient precision to put in evidence the zonal winds on Jupiter
