Thread-topic: anomalies in time series

Ferret users,

I have a time series of annual global temperature anomalies. I would like to determine all the anomalies above/below a given threshold (say 1 degree) and then determine the year of the anomaly. This seems like it should be straightforward but I am not sure how to do it. Thank you.
