Satellite Derived Chlorophyll-a anomaly in the central Pacific Ocean



Current ENSO Status:
ENSO Neutral conditions are prevailing in the equatorial Pacific Ocean.

Approach

El Niño Southern Oscillation (ENSO), a global climate phenomenon, occurs in the tropical Pacific Ocean with its impacts on global and regional weather systems across the world.
NRSC conducted a new study, using satellite-measured Chl-a, Sea Surface Temperature (SST) based Oceanic Niño Index (ONI) for the period 2003 to 2023, demonstrating that a marked decline of spring bloom Chl-a as an early indicator compared to ONI for El Nino onset prediction.
This study revealed that Chl-a exhibits a significant inverse relationship with ONI during past El Niño (2004-2005, 2006-2007, 2015-2016, 2019-2020 & 2023-2024) and La Niña (2007–2008, 2011–2012, & 2017–2018) events. Based on this study a new ENSO outlook climate service is developed. Read More..

About

NICES is a multi-institutional venture with participation of ISRO/DOS centres and other Departments and national Institutions under various Ministries which will help to strengthen the information base with contributions (in-situ observational and model outputs) from the participating organisations. NICES has been functioning under the guidance of NICES-Programme Management Council (PMC) with a composition of members from inter and intra-departmental institutions under the Chairmanship of Director, NRSC.

NICES envisages realisation of national level climate database generation, derived from Indian and other Earth Observation satellites from polar and geostationary missions for climate change impact assessment and mitigation.
