demodata: foehnix Demo Data Set

In retostauffer/Rfoehnix: Objective Foehn Diagnosis

foehnix Demo Data Set

Description

The foehnix package comes with two sets of meteorological observations: one for Tyrol, Austria, and one for Southern California, USA. Both data sets come with observations from two stations, one valley station (or target station) and one station further upstream of the main foehn wind direction (crest station) used to filter the data (see foehnix_filter). For Tyrol, observations for station Ellbögen (valley) and station Sattelberg (crest) are included, the Californian data set consists of the crest station 'Lucky Five Ranch' and the valley station 'Viejas Casino and Resort'. More details are provided in the 'Details' section.

Usage

demodata(
  which = c("tyrol", "ellboegen", "sattelberg", "california", "viejas", "luckyfive")
)

Arguments

which

which = "tyrol" returns the combined Tyrolean data set (A) and which = "california" the combined Californian data set (USA), a time series object which contains measurements from both stations (valley/crest). Else, the data for a specific site will be returned (see 'Examples'/'Usage').

Details

The Tyrolean data set consists of station Elbögen located in the Wipp valley, an area well known for south foehn events. The second station called Sattelberg is located 18km (11.5mi) south of Ellbögen close to the main alpine ridge and is used as upstream crest station.

• Ellbögen: 11.42889 E/47.18694 N, 1080 meters above mean sea level

• Sattelberg: 11.47889 E/47.01083 N, 2107 meters above mean sea level

Hourly time series objects (class 'zoo'; UTC) including the following variables:

• dd: wind direction in degrees, meteorological format (0/360 correspond to 'wind from north', 90 to 'wind from east', 180 'wind from south', and 270 'wind from west')

• ff: wind speed in meters per second

• p: station pressure in hectopascal

• rh: relative humidity in percent

• t: dry air temperature in degrees Celsius

The Californian data sets consist of two stations located in the southern part of the state. Station 'Viejas' is installed next to the Viejas Casino and Resort located in Alpine, CA (valley station), the station 'Lucky Five Ranch' is located 22km (14mi) northwest of the Viejas Casino close to the main ridge of the Sierra Nevada mountain range and is used as the upstream crest station.

• Viejas Casino and Resort: -116.70437 E/32.84559 N, 715 meters above mean sea level

• Lucky Five Ranch: -116.528 E/32.9331 N, 1445 meters above mean sea level

Hourly time series objects (class 'zoo'; UTC) including the following variables:

• air_temp: dry air temperature in degrees Celsius

• relative_humidity: relative humidity in percent

• wind_speed: wind speed in meters per second

• wind_direction: wind direction in degrees, meteorological format (0/360 correspond to 'wind from north', 90 to 'wind from east', 180 'wind from south', and 270 'wind from west')

• wind_gust: wind gust speed in meters per second
