<div dir="ltr">Dear all,<div><br></div><div> I want to calculate the correlation between SST and precipitation. The SST is NetCDF file and the precipitation is TXT file. For example, the precipitation is the annual value of one region: <table border="0" cellpadding="0" cellspacing="0" width="144" style="border-collapse:collapse;width:108pt">
