Hello , a fellow undergrad here! When i plot the temp trend over the 1940 to 1969 i see a spike of heating in the lower stratosphere. Something between +1.5 to +2K per 30yrs. I’m trying to understand if the data is not that reliable (since we talking about a pre-satellite era, with nearly non existent measurements for the upper atmosphere) or maybe the volcanic eruption of 1963 shifts my polyfit higher. Any suggestions ?
