  1. GHRSST Applications: Regional ScaleUsing GHRSST datasets to observe the El Niño Southern Oscillation (ENSO) in the Equatorial Pacific Ocean

  2. What is El Niño Southern Oscillation (ENSO)? Neutral La Niña El Niño

  3. GHRSST Datasets for Regional Climate Study Scenario Scenario:Using GHRSST datasets to observe the El Niño Southern Oscillation (ENSO) in the Equatorial Pacific Ocean • Needs: • Long time record (> 10 years) • Gridded • Global • Foundation Temperature • GHRSST dataset that fit these needs: • GHRSST Level 4 AVHRR Optimal Interpolation Global Blended SST Analysis • 1981 – present, 25 km • GHRSST Level 4 MUR Global Foundation SST Analysis • 2002 – present, 1 km

  4. GHRSST observations: ENSOGHRSST L4 AVHRR_OI Global Blended SST Analysis Neutral 1 Jan 1997 El Niño 1 Dec 1997 La Niña 1 Dec 1998 [Images acquired using PO.DAAC’s Live Access Service]

  5. A New Type of El Niño Emerges… El Niño Modoki, Central Pacific (CP)-El Niño, warm-pool El Niño, or dateline El Niño
