Short summary
We developed a ground-based 110.836 GHz radiometer developed to measure the stratospheric ozone profile over Seoul, South Korea. To ensure precise measurements and correct the atmospheric spectrum, we employed hot–cold calibration along with continuous tipping curve calibration. Prior to the retrieval process, both pointing and frequency offsets were corrected. We provide stratospheric ozone profiles from 2016 to 2021, which are compared with collocated satellite observations.
