Get Arctic Oscillation (AO) data

Source: R/get_ao.R

get_ao Downloads AO data returning a data.frame

get_ao()

Value

data.frame

Note

From https://www.ncdc.noaa.gov/teleconnections/ao/: AO index is obtained by projecting the AO loading pattern to the daily anomaly 1000 millibar height field over 20N-90N latitude. The AO loading pattern has been chosen as the first mode of EOF analysis using monthly mean 1000 millibar height anomaly data from 1979 to 2000 over 20N-90N.
