Southern California Water Temperature Index, Monthly, v1.0
Listed in Spray Underwater Glider data from Instrument Development Group, Scripps Institute of Oceanography, University of California, San Diego
The Southern California Temperature Index (SCTI) is derived from the sea water temperature records of the California Underwater Glider Network (CUGN), a collection of over 15 years of Spray underwater glider measurements.
Description
The CUGN data provides climatologies and the interannual anomaly of the sea water temperature near the California Coast which are used to generate the SCTI. The Southern California Temperature Index represents a smoothed temperature anomaly variability near the coast of California, similar to the Oceanic Nino Index (ONI), using local in-situ data to provide a regional index.
The Socal Index is calculated using a subset of the CUGN Line 90 glider climatology data. The index is created using water temperature data at 50-m depth for the nearhsore 200-km section of all Line 90 data extending back to 2006. These data are averaged over the 200-km section to provide a time-series of the average temperature for this area at 50-m depth.

The glider data is then averaged at a 3-month (90-day) interval. This aligns the time signature of the index with the ONI and allows for comparison of the two data products. The SCTI data are updated monthly after the monthly NOAA Nino 3.4 data are released.
An Oceanic Niño Index variable is included with the SCTI. This variable is calculated using the Niño 3.4 index, and applying a 3-month average to it. The Niño 3.4 index is obtained from the NOAA Climate Prediction Center.
