Functions for Reading, Visualising and Analysing Ocean Data Derived from Satellites for Oceanographic Applications
Visualisation and Analysis of Ocean Data Derived from Satellites
Description: With ‘satin’ functions, visualisation, data extraction and further analysis like producing climatologies from several images, and anomalies of satellite derived ocean data can be easily done. Reading functions can import a user defined geographical extent of data stored in netCDF files. Currently supported ocean data sources include NASA’s Oceancolor web page https://oceancolor.gsfc.nasa.gov, sensors VIIRS-SNPP; MODIS-Terra; MODIS-Aqua; and SeaWiFS. Available variables from this source includes chlorophyll concentration, sea surface temperature (SST), and several others. Data sources specific for SST that can be imported too includes Pathfinder AVHRR https://www.ncei.noaa.gov/products/avhrr-pathfinder-sst and GHRSST https://www.ghrsst.org. In addition, ocean productivity data produced by Oregon State University http://sites.science.oregonstate.edu/ocean.productivity can also be handled previous conversion from HDF4 to HDF5 format. Many other ocean variables can be processed by importing netCDF data files from two European Union’s Copernicus Marine Service databases https://marine.copernicus.eu, namely Global Ocean Physical Reanalysis and Global Ocean Biogeochemistry Hindcast.
