refactor using 1981-2010 as the reference climatology.

2

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...

NFFD doesn't match ClimateNA

NFFD not matching between climr and ClimateNA. at an annual level, it seems to be related to longitude  on a monthly level it is confined to latitudinal regions...

evaluate climr::lapse_rate() against terra::focalReg()

terra::focalReg() can also be used to calculate a lapse rate. if it provides equal or better results, we would be better to use terra, as then we don't need our...

Tmax speckling in northern canada
