A data frame containing the Goddard Institute for Space Studies (GISS) time series called LOTI (Land-Ocean Temperature Index) of surface temperature anomaly.
data(giss)This is data frame with columns named year for decimal year
(sampled monthly and represented here at mid-month, i.e. the first sample in
any given year is at year+1/24) and index for the temperature anomaly.
The resolution of the latter is 0.01C. The details of the original data
processing are provided in [1] and [2], and the site of the (Land-Ocean
Temperature Index. Anyone using the present dataset is advised very strongly
to read the NASA documents on changes to the processing of the data [3].
