Abstract
The sea surface temperature (SST) data were provided by the United Kingdom Meteorological Service (UKMO), and correspond to the Sea Surface Temperature and Sea Ice Analysis System (OSTIA), which is part of the data set of the GHRSST project -PP (GODAE High Resolution Sea Surface Temperature Pilot Project). The OSTIA system uses data from a combination of infrared and microwave satellites, as well as in-situ data to allow effective skew correction. The estimated RMS error is 0.6K in high resolution, in quasi-real time (Stark et al., 2007).
The Oceanographic Institute of the Ecuadorian Navy post-processes these daily data (L4), at a resolution of 4km, and generates, as an INOCAR oceanographic product, the SST and SST anomaly charts averaged over 7 days in the Southeast Pacific domain. considering a week of analysis from Monday to Sunday. For the anomaly fields, the Levitus climatology from the 2005 Marine Oceanic Atlas (WOA05, Locarnini et al., 2006) was used.
The anomaly chart shows the difference between the current sea temperature and the expected value for the date based on historical records (Levitus climatology). Values above the average are known as a positive anomaly, and those below the average are known as a negative anomaly.
