Providing ocean satellite data for the Arctic and Antarctic

Mapping Projected Datasets in R

Submitted by pwadmin on Wed, 02/03/2021 - 13:17
This example demonstrates accessing and working with sea ice data served by ERDDAP in polar projected coordinates. Find and preview data in ERDDAP, create URL requests to download projected data from ERDDAP, use the latitude/longitude grids associated with a projected dataset, make maps of projected data with ggplot.

Scripts for converting projected coordinates added

Two new R scripts that demonstrate converting to and from polar projections are now available in the PolarWatch Code Gallery. Thank you to Doug Kinsey and Randy Cutter from NOAA SWFSC for contributing and sharing their code samples. These scripts access satellite and in-situ data from the PolarWatch ERDDAP and demonstrate transforming the coordinates using R spatial dataframes.
