[gradsusr] GFS hourly clouds output (Ivan Toman)

Tue Oct 4 16:24:48 EDT 2016

Hello All,
I need help to calculate lag correlation. I have two monthly time series. I
want to plot lag-lead correlation lag-30 to lead-30. Would you please help
me to calculate lag-lead correlation. I want to plot similar to the plot
which I have attached here with.
