This map shows monthly outgoing longwave radiation anomalies for the globe.
This map shows monthly outgoing longwave radiation (OLR) anomalies in units of Watts/m2. The period used for computing the climatology is 1974-present. Negative anomalies in green on the map imply increased cloudiness and enhanced likelihood of precipitation. Positive anomalies in brown imply decreased cloudiness and precipitation. These relationships work best in tropical regions.
These data are from the NOAA NCEP Climate Prediction Center.
