nov from IRI Analyses NOAA NCEP CPC GOB V0px NMME_drought monthly NMME_deg1p0 correl_diff NMME_MME_prcp hind_obs_OptPersist SPI3: In this dataset SPI values calculated on merged NMME_MME_prcp hindcast data and observed monthly GOB data over Jan 1982-Dec 2010 are correlated with SPI calculated from GOB alone, and this correlation is compared to the equivalent correlation from the optimal persistence calculation to flag which is larger. This flag will be used to make a skill mask for the MME/Optimal Persistence drought forecast tool. In this dataset the start time corresponds to the last calendar month of observations before forecast data are appended, NOT a 0000 1 Jan forecast start, for example..
