wind_rose_catalog.Rd

Lists the pre-built global wind roses available for download with download_wind_rose(). Currently these are built from 10 m CFSR wind for 1979-2010, at CFSR's native resolution (about 0.31 degrees), with trans = 1.

  • year, month: the year and month the file covers, or NA where it spans several.

  • first, last: the first and last year-months covered.

  • n_steps: the number of hourly time steps summarized.

  • trans: the wind speed transformation the rose was built with (see wind_rose()).

  • file, bytes, md5: file name, size in bytes, and MD5 checksum.
