coops: Get NOAA co-ops data

Description

Get NOAA co-ops data

Usage

coops_search(
  begin_date = NULL,
  end_date = NULL,
  station_name = NULL,
  product,
  datum = NULL,
  units = "metric",
  time_zone = "gmt",
  application = "rnoaa",
  ...
)

Value

List, of length one or two.

• metadata A list of metadata with slots id, name, lat, lon

• data A data.frame with data

Arguments

begin_date

(numeric) Date in yyyymmdd format. Required

end_date

(numeric) Date in yyyymmdd format. Required

station_name

(numeric) a station name. Required

product

(character) Specify the data type. See below for Details. Required

datum

(character) See below for Details. Required for all water level products.

units

(character) Specify metric or english (imperial) units, one of 'metric', 'english'.

time_zone

(character) Time zone, one of 'gmt', 'lst', 'lst_ldt'. For GMT, we convert time stamps to GMT. For LST, we look up the time zone of the station with its lat/lon values, and assign that time zone. When product="predictions" we don't adjust times at all.

application

(character) If called within an external package, set to the name of your organization. Optional

• air_temperature - Air temperature as measured at the station

• water_temperature - Water temperature as measured at the station

• wind - Wind speed, direction, and gusts as measured at the station

• air_pressure - Barometric pressure as measured at the station

• air_gap - Air Gap (distance between a bridge and the water's surface) at the station

• conductivity - The water's conductivity as measured at the station

• visibility - Visibility from the station's visibility sensor. A measure of atmospheric clarity

• humidity - Relative humidity as measured at the station

• salinity - Salinity and specific gravity data for the station

• one_minute_water_level - One minute water level data for the station

• predictions - 6 minute predictions water level data for the station

• hourly_height - Verified hourly height water level data for the station

• high_low - Verified high/low water level data for the station

• daily_mean - Verified daily mean water level data for the station

• monthly_mean - Verified monthly mean water level data for the station

• datums - datums data for the stations

• currents - Currents data for currents stations
