sst: Sea surface temperature data from remote-sensing products

In eeholmes/SardineForecast: Indian Oil Sardine Data, Code and References for Papers on Forecasting

Description

The SST satellite data were downloaded from the NOAA ERDDAP server using Roy Mendelssohn's rerddapXtracto R package which uses the ropenscirerddap R package available on CRAN. The R code used to download the data is in the extdata/get_satelite_data folder. See examples for how to find the file. Units are degree Celsius.

Usage

sst

Format

A data frame with:

Year

The year

Month

The month

SST.1 to SST.13

Average monthly SST averaged over boxes 1 to 13. Units are degree Celcius.

SSTICOAD.1 to SSTICOAD.13

Average monthly SST averaged over boxes 1 to 13. Units are degree Celcius.

Details

There are two SST data sets: AVHRR and ICOADS.

AVHRR The SST differential upwelling indices were computed from the SST Daily Optimum Interpolation (OI), AVHRR Only, Version 2.1, Final 0.25 degree grid, Global data downloaded from the NOAA ERDDAP server. These are daily data. They daily data were averaged over all days in each month to produce monthly averages. The SST estimates use the Advanced Very-High Resolution Radiometer (AVHRR) instruments. AVHRR is accurate for close to the coast and thus could be used for our SST differential upwelling index.

The SST data were downloaded from the NOAA ERDDAP server. See https://coastwatch.pfeg.noaa.gov/erddap/info/ncdcOisst21Agg/index.html.

ICOADS The SST was extracted from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) collection of surface marine data Data from 1960 onward were used, which are on a 1°x1° grid.

The ICOADS SST data were downloaded from the NOAA ERDDAP server. https://coastwatch.pfeg.noaa.gov/erddap/info/esrlIcoads1ge/index.html More information on the ICOADS data are available at https://coastwatch.pfeg.noaa.gov/erddap/info/esrlIcoads1ge/index.html The R code used to download the data is in the extdata/get_satelite_data folder. See examples for how to find and view the files. The SST values were averaged across thirteen 1 degree by 1 degree boxes which roughly parallel the bathymetry.
