NOAA AOML Atlantic 3 Data ProductsEntry ID: AOML_ATL3
Abstract: While ENSO accounts for the largest single contribution to inter-annual climate variability globally, it is not the only source, particularly for the extratropics and the Indian and Atlantic ocean sectors of the tropics. A number of studies have documented climatic anomalies in regions surrounding the tropical Atlantic showing clear relationships between regional climate anomalies and tropical ... basin-scale patterns of Atlantic SST. Many of the observed anomalies are accompanied by extreme precipitations in the tropical Atlantic and several regions of Africa.
The Atlantic 3 (ATL3) region is delimited by 3°N-3°S, 20°W-0°
- Sea Surface Temperature
SST data from different sources are used here. SST data from 1985 to mid-1998 are obtained from the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA polar orbiting satellite.
For more recent years (1998-2002), data obtained from observations made by a radiometer on board the Tropical Rainfall Measuring Mission (TRMM) satellite are used. The TRMM Microwave Imager (TMI) is a well-calibrated radiometer that contains lower frequency channels required for SST retrievals (More info). The TMI data are provided as daily sets, available from December 1997 to the present.
Since May, 2002, data from the Advanced Microwave Scanning Radiometer (AMSR-E) aboard NASA's Aqua spacecraft are available and are also used.
- Sea Height Anomaly
Gridded seven days delay time (DT) data are generally available until six month prior to the current date. We use the inhomogeneous DT data set from AVISO. For more recent dates, we use the near real time (NRT) daily data set
