get_sounding(wmo_id, yy, mm, dd, hh, metadata = FALSE)

Source

http://weather.uwyo.edu/upperair/sounding.html

Arguments

wmo_id

international WMO station code (e.g. 11035 for Vienna)

yy

year - single number (e.g. 2010)

mm

month - single number (e.g. 5)

dd

day - single number (e.g. 23)

hour - single number (e.g. 0)

metadata

- logical, whether to return metadata of downloaded sounding; default FALSE

Value

Returns two lists with values described at: weather.uwyo.edu ; The first list contains:

1. pressure - pressure [hPa]

2. altitude - altitude [meters]

3. temp - temperature [degree Celsius]

4. dpt - dew point temperature [degree Celsius]

5. wd - wind direction [azimuth in degrees]

6. ws - wind speed [knots]

If metadata = TRUE then retrieved data is wrapped into a second list containing available metadata
