Description Data Sources A note about NCDF data The meteo family of functions
rnoaa is an R interface to NOAA climate data.
Many functions in this package interact with the National Climatic Data
Center application programming interface (API) at
https://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
cpc_prcp
- rainfall data from the NOAA Climate
Prediction Center (CPC)
arc2
- rainfall data from Africa Rainfall Climatology
version 2
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.
meteo
family of functionsThe 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()
)
