I am looking to gather the 30 year average data of daily normal weather for counties. I used the following code to check the stations in FIPS and then use a station from the list.
stations <- ncdc_stations(datasetid='NORMAL_DLY', locationid='FIPS:26163') stations$data
out2 <- ncdc(datasetid='NORMAL_DLY', stationid='GHCND:USW00094847', datatypeid='dly-tavg-normal', startdate = '2010-01-01', enddate = '2010-12-31', limit = 365)
Why do we need to provide a range of dates when data is averaged already over 30 years? Is this command uses data averaged over 1981-2010 from link below or older than that?
