rnoaa

Project Status: Active – The project has reached a stable, usable state and is being actively developed. cran checks R-check codecov.io rstudio mirror downloads cran version

rnoaa is an R interface to many NOAA data sources. We don't cover all of them, but we include many commonly used sources, and add we are always adding new sources. We focus on easy to use interfaces for getting NOAA data, and giving back data in easy to use formats downstream. We currently don't do much in the way of plots or analysis. To get started see: https://docs.ropensci.org/rnoaa/articles/rnoaa.html

Data sources in rnoaa

Help/Getting Started

Documentation is at https://docs.ropensci.org/rnoaa/, and there are many vignettes in the package itself, available in your R session, or on CRAN (https://cran.r-project.org/package=rnoaa). The tutorials:

  • Getting started - start here
  • NOAA Buoy vignette
  • NOAA National Climatic Data Center (NCDC) vignette (examples)
  • NOAA NCDC attributes vignette
  • NOAA NCDC workflow vignette
  • Sea ice vignette
  • Severe Weather Data Inventory (SWDI) vignette
  • Historical Observing Metadata Repository (HOMR) vignette
  • Complementing air quality data (ropenaq (https://github.com/ropensci/ropenaq)) with weather data using rnoaa

netcdf data

Some functions use netcdf files, including:

  • ersst
  • buoy
  • bsw
  • argo

You'll need the ncdf4 package for those functions, and those only. ncdf4 is in Suggests in this package, meaning you only need ncdf4 if you are using any of the functions listed above. You'll get an informative error telling you to install ncdf4 if you don't have it and you try to use the those functions. Installation of ncdf4 should be straightforward on any system. See https://cran.r-project.org/package=ncdf4

NOAA NCDC Datasets

There are many NOAA NCDC datasets. All data sources work, except NEXRAD2 and NEXRAD3, for an unknown reason. This relates to ncdc_*() functions only.

NOAA NCDC Attributes

Each NOAA dataset has a different set of attributes that you can potentially get back in your search. See https://www.ncdc.noaa.gov/cdo-web/datasets for detailed info on each dataset. We provide some information on the attributes in this package; see the vignette for attributes (https://docs.ropensci.org/rnoaa/articles/ncdc_attributes.html) to find out more
