SW Flux Estimated from Synoptic Reports
• Estimate radiation anomalies due to cloud cover anomalies to bridge between synoptic cloud reports and GEBA and ISCCP FD solar radiation data
SW Cloud Cover Radiative Forcing (CCRF) anomaly =(mean SW CRF / mean cloud cover) total cloud cover anomaly )

SW Flux Estimated from Synoptic Reports
correlation = 0.87

SW Flux Estimated from Synoptic Reports
correlation = 0.87
×1.8 to account for the positive correlation between cloud cover and cloud thickness anomalies
