Description
rnoaa is an R interface to NOAA climate data.
Data Sources
Many functions in this package interact with the National Climatic Data
Center application programming interface (API) at
http://www.ncdc.noaa.gov/cdo-web/webservices/v2, all of
which functions start with ncdc_
. An access token, or API key, is required to use all
the ncdc_
functions. The key is required by NOAA, not us. Go to the link given above
to get an API key. More NOAA data sources are being added through time. Data sources and their
function prefixes are:
-
buoy_*
- NOAA Buoy data from the National Buoy Data Center
-
gefs_*
- GEFS forecast ensemble data
-
ghcnd_*
- GHCND daily data from NOAA
-
isd_*
- ISD/ISH data from NOAA
-
homr_*
- Historical Observing Metadata Repository (HOMR) vignette
-
ncdc_*
- NOAA National Climatic Data Center (NCDC) vignette (examples)
-
seaice
- Sea ice vignette
-
storm_
- Storms (IBTrACS) vignette
-
swdi
- Severe Weather Data Inventory (SWDI) vignette
-
tornadoes
- From the NOAA Storm Prediction Center
-
argo_*
- Argo buoys
-
coops_search
- NOAA CO-OPS - tides and currents data
A note about NCDF data
Functions to work with buoy data use netcdf files. 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 the buoy
functions. You'll get an informative error telling you to install ncdf4
if you don't have it and you try to use the buoy functions.The <code>meteo</code> family of functions
The meteo
family of functions are prefixed with meteo_
and provide
a set of helper functions to:
- Identify candidate stations from a latitude/longitude pair
- Retrieve complete data for one or more stations (
meteo_coverage()
)
