Monthly Precipitation Anomaly

This map shows monthly precipitation anomalies for the globe.

This map shows monthly precipitation anomalies in units of mm/month based upon precipitation estimates from the CAMS_OPI dataset. The period used for computing the climatology is 1979-2000. Green areas on the map indicate where precipitation was above the long-term normal for the month, and brown areas on the map indicate where precipitation was below normal. Contours are drawn at increments of +/- 10, 25, 50, 100, ... 500 mm/month.

These data are from the NOAA Climate Prediction Center's CAMS_OPI data set. "CAMS" is an acronym for the "Climate Anomaly Monitoring System" in use at the Climate Prediction Center (CPC) at the U.S. National Centers for Environmental Prediction (NCEP). "OPI" stands for "Outgoing longwave radiation Precipitation Index" (the satellite precipitation estimates are based on emitted longwave radiation observed by polar-orbiting satellite.)
