Inter-Comparison of OLR Products for Tropical Annual Mean Anomaly

Explore the comparison study of various Outgoing Longwave Radiation (OLR) products in the tropics from 1979-2005 through an in-depth analysis. Conducted by Hai-Tien Lee, Arnold Gruber, Robert G. Ellingson, and Istvan Laszlo, this research aims to enhance understanding of OLR anomalies. The paper, presented at the WRF Users’ Workshop in 2007, includes insights on ENSO regional OLR variations and more.
