| Abstract : | Differential rotation in the Sun is a pivotal topic of investigation due to its significance in understanding the Solar Dynamo and Solar cycle models. While our comprehension of the photospheric and internal differential rotation within the Sun has matured, the rotational behavior of the solar atmosphere above the photosphere remains a subject of ongoing debate, largely due to conflicting findings across various studies. In this study, we capitalize on the wealth of multi-wavelength data obtained from the Solar Dynamics Observatory's Atmospheric Imaging Assembly (SDO/AIA), enabling us to explore the solar atmosphere's rotation profile across a range of temperatures (height). To achieve this, we developed a new method based on image processing to measure the rotation profile of the solar atmosphere using the high-resolution SDO/AIA multi-wavelength data for 2010-22. Our preliminary findings indicate a trend of increasing equatorial rotation rates with rising temperature (height) and a reduction in the differential nature of rotation in higher atmospheric layers. Additionally, we also notice a trend in the yearly variation of the rotation rates of different layers of the Solar atmosphere. |
