Stratospheric Cooling Threatens Global Climate, Satellite Data Reveals
Scientists developed a method to combine different climate data records by using measurements from high-resolution limb sounders. They applied this method to global stratospheric temperature data from two different instruments, SSU and AMSU, extending the SSU record to the present. The data sets were connected using measurements from MIPAS. The extended SSU data set matches well with temperatures from MLS on the Aura satellite, showing a cooling trend in the upper stratosphere. It also aligns with climate model simulations, capturing variations in cooling trends over different time periods.
