Currently the reference climatology is nominally 1961-1990. However, the PRISM and climr mosaic are 1981-2010. this introduces errors into the reference climatology during translation to 1961-1990. once the climr mosaic is ready, we would ideally change the reference climatology to 1981-2010, with functionality to calculate normals for other periods.
However, that's not a small task since it will require recalculating and re-uploading all GCM anomalies. an alternative is to maintain the 1961-1990 reference period and document the errors.
