Note that the baseline climate is computed using 1986-2015 data from the same reanalysis product. In addition, the displayed surface temperature anomaly fields were smoothed in longitude and latitude using a boxcar filter.
NetCDF.jl to pre-process the NetCDF data into surface temperature anomalies JSON outputs.
surface-nets to compute the contours levels.
