Description
Data Source Catalogues Online for Southern Ocean Ecosystem Research.
Description
Obtains lists of files of remote sensing collections for Southern Ocean surface properties. Commonly used data sources of sea surface temperature, sea ice concentration, and altimetry products such as sea surface height and sea surface currents are cached in object storage on the Pawsey Supercomputing Research Centre facility. Functions to retrieve these object storage catalogues are provided. The catalogues include complete collections of datasets Reynolds et al. (2008) "NOAA Optimum Interpolation Sea Surface Temperature (OISST) Analysis, Version 2.1" <doi:10.7289/V5SQ8XB5>, Spreen et al. (2008) "Artist Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) sea ice concentration" <doi:10.1029/2005JC003384>. In future releases helpers will be added to identify particular data collections and target specific dates for earth observation data for reading, as well as helpers to retrieve data set citation and provenance details.

sooty 
The goal of sooty is to provide data of interest to Southern Ocean research.
At the moment we only return lists of files available in object storage, but future versions will provide direct access to the data in these files with helper functions defined here.
To see what files we have in object storage, use
library(sooty)
(files <- tibble::as_tibble(sooty_files()))

These are all directly useable source identifiers that a GDAL-enabled package can read.
In time we will provide helpers to pick specific data sets and open data for a given date.
For now we only have manual handling, such as
library(terra)
#> terra 1.7.83
file <- files$source[which.max(files$date) ]
print(file)
#> [1] "/vsis3/idea-10.7289-v5sq8xb5/www.ncei.noaa.gov/data/sea-surface-temperature-optimum-interpolation/v2.1/access/avhrr/202411/oisst-avhrr-v02r01.20241130_preliminary.nc"
Sys.setenv(AWS_S3_ENDPOINT="projects.pawsey.org.au",
