I am currently conducting my thesis research on corals in the Galapagos Islands, and understanding El Niño events is critical to my analysis. Specifically, I am looking for El Niño-related indices (e.g., El Niño 1+2 SST Index, MEI, or similar) with a weekly temporal resolution. Datasets I have encountered, such as those from the NOAA Physical Science Lab, provide monthly data (https://psl.noaa.gov/data/timeseries/month/).
The only weekly dataset I’ve been able to find is NASA’s Sea Surface Level data (ENSO Index - Sea Level; https://sealevel.jpl.nasa.gov/data/vital-signs/el-nino/), but it would be ideal to find indices more directly tied to the Tropical Eastern Pacific where the Galapagos are located.
Does anyone know of other sources, institutions (from the US, Ecuador, Perú, etc), or repositories that provide weekly El Niño indices with this temporal resolution needed? Any help or direction would be greatly appreciated!
I would simply compute monthly means of your data to compare to the monthly mean ENSO indices. The ENSO indices represent climate (roughly, month to month variations and longer) rather than weather (roughly, day to weeks) related variations. I cannot grasp why you would need weekly ENSO indices. Alternatively, you could simply interpolate from the monthly mean data to weekly. In this case you would have weekly data but effectively, however, you would not have increased the temporal resolution of your data.
