Outgoing Longwave Radiation (OLR)

The weekly OLR maps are now being updated on a daily basis using the latest 7 days of OLR data available. The OLR hovmoller plots are also being updated daily and are a 7-day running mean of the latest daily data. However, the last three data points on the hovmollers are 6-day, 5-day and 4-day means.

The OLR anomaly plots are now being provided in both PSL's standard shading and an alternate shading scheme.
