Temperature trends in the upper stratosphere, particularly above &#8764;&#8201;45&#8201;km, are difficult to quantify due to a lack of observational data with high vertical resolution in this region that span multiple decades. The recent v7.3 upper-stratospheric (35&#8211;60&#8201;km) temperature data product from the Optical Spectrograph and InfraRed Imager System (OSIRIS) includes over 22&#160;years of observations that can be used to estimate temperature trends. The trends in OSIRIS temperatures over 2005&#8211;2021 are compared to those from two other satellite limb instruments: Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) and Microwave Limb Sounder (MLS). We find that the upper stratosphere cooled by &#8764;&#8201;0.5 to 1&#8201;K per decade during this period. Results from the three instruments are generally in agreement. By merging the OSIRIS observations with those from channel&#160;3 of the Stratospheric Sounding Unit (SSU), we find that the stratosphere cooled at a rate of approximately &#8722;0.6&#8201;K per decade between 1979 and 2021 near 45&#8201;km, in agreement with earlier results based on SSU and MLS. The similarity between OSIRIS temperature trends and those from other records improves confidence in observed upper-stratospheric temperature changes over the last several decades.
