IRI Analyses NOAA NCEP CPC GOB V0px NMME_drought monthly NMME_deg1p0 correl_diff NMME_MME_prcp hind_obs_OptPersist SPI12: 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.

IRI Analyses NOAA NCEP CPC GOB V0px NMME_drought monthly NMME_deg1p0 resampled seasonality_retained SPIcorrel: In this dataset the Start Time designates the latest month with real observations, NOT a forecast start time at 0000 1 Jan, for example. So, for SPI3, with a Jan start time and lead of 1, the forecast is for Feb, and there are 2 months of overlap (Dec and Jan) between SPI3 and SPI2. For SPI3 with a Jan start time and a lead of 2, the forecast is for Mar, and there is 1 month of overlap (Jan) between SPI3 and SPI1
