AreaClimateIndicator: Read daily station data of the Norwegian Meteorological...

In metno/esd: Climate analysis and empirical-statistical downscaling (ESD) package for monthly and daily data

Read daily station data of the Norwegian Meteorological Institute from thredds netCDF using OpenDAP

Description

AreaClimateIndicator returns area-based climate indicators provided through the Met Norway thredds server, some of which are described in Benestad et al (2022) "Global hydro-climatological indicators and changes in the global hydrological cycle and rainfall patterns", PLOS Climate, PCLM-D-21-00079R1, DOI: 10.1371/journal.pclm.0000029, and an extension of those to temperature and other thresholds.

Usage

AreaClimateIndicator(
  param = "precip",
  is = "Global",
  it = "annual",
  FUN = "mean",
  threshold = 1,
  plot = TRUE,
  verbose = FALSE,
  url = "https://thredds.met.no/thredds/dodsC/metusers/rasmusb/"
)

Arguments

param	The element to read c('t2m','tmax','tmin','precip')
is	the area or index space to select domain c('Global','50S-50N','Arctic')
it	Index time to select times scale c('as.annual','as.4seasons','as.monthly','day')
FUN	is the function used in aggregation
threshold	select area of precipitation exceeding 1 mm/day or temperature above 0C (the freezing point)

Examples

## Get the daily minimum temperature for Oslo-Blindern (station ID 18700)
## Not run: 
x <- AreaClimateIndicator()
y <- AreaClimateIndicator(param='t2m',is='Arctic',threshold=0)
z <- AreaClimateIndicator(param='precip',is='50S-50N',it='day',threshold=1)
w <- AreaClimateIndicator(param='t2m',it='max',threshold=40)

## End(Not run)
