lcd: Local Climitalogical Data from NOAA

Description

Local Climitalogical Data from NOAA

Usage

lcd(station, year, ...)
lcd_cleanup(x)

Arguments

station

(character) station code, e.g., "02413099999". we will allow integer/numeric passed here, but station ids can have leading zeros, so it's a good idea to keep stations as character class. required

year

(integer) year, e.g., 2017. required

...

curl options passed on to crul::verb-GET

x

result of a call to lcd(). required

Value

a data.frame, with many columns, and variable rows depending on how frequently data was collected in the given year

a data.frame with many columns. the first 10 are metadata:

• station

• date

• source

• latitude

• longitude

• elevation

• name

• report_type

• call_sign

• quality_control

And the rest should be all data columns. See Note about data joined together.

Other groups of fields under the following:

• wnd: wind

• tmp: air temperature

• aa: LIQUID-PRECIPITATION

• aj: snow depth

• ay: PAST-WEATHER-OBSERVATION

• oc: WIND-GUST-OBSERVATION

• dew: dew point

• slp: sea level pressure

• cig: sky condition

• ka: extreme air temperature

• ma: atmospheric pressure

• md: atmospheric pressure change

• ga: SKY-COVER-LAYER

• ge: SKY-CONDITION-OBSERVATION

• gf: SKY-CONDITION-OBSERVATION

• ia: GROUND-SURFACE-OBSERVATION

• mw: PRESENT-WEATHER-OBSERVATION

• rem: remarks

Details

lcd_cleanup() takes the output of lcd() and parses additional columns that have comma separated strings into separate columns with headings; so lcd_cleanup() adds many additional columns

Examples

# NOT RUN {
lcd(station = "01338099999", year = "2017")
lcd(station = "01338099999", year = "2015")

lcd(station = "02413099999", year = "2009")
lcd(station = "02413099999", year = "2001")

# pass curl options
lcd(station = "02413099999", year = "2002", verbose = TRUE)

# clean up columns
w <- lcd(station = "01338099999", year = "2017")
w
lcd_cleanup(w)
# }
