meteo_ogimet: Scrapping meteorological (Synop) data from the Ogimet webpage

Description

Downloading hourly or daily (meteorological) data from the Synop stations available at https://www.ogimet.com/

Usage

meteo_ogimet(
  interval,
  date = c(Sys.Date() - 30, Sys.Date()),
  coords = FALSE,
  station,
  precip_split = TRUE,
  allow_failure = TRUE
)

Value

A data.frame of measured values with columns describing the meteorological parameters (e.g. air temperature, wind speed, cloudines). Depending on the interval, at a given hour or day. Different parameters are returned for daily and hourly datasets.

1. station_ID - WMO station identifier

2. Lon - longitude

3. Lat - latitude

4. Date - date (and time) of observations

5. TC - air temperature at 2 metres above ground level. Values given in Celsius degrees

6. TdC - dew point temperature at 2 metres above ground level. Values given in Celsius degrees

7. TmaxC - maximum air temperature at 2 metres above ground level. Values given in Celsius degrees

8. TminC - minimum air temperature at 2 metres above ground level. Values given in Celsius degrees

9. ddd - wind direction

10. ffkmh - wind speed in km/h

11. Gustkmh - wind gust in km/h

12. P0hpa - air pressure at elevation of the station in hPa

13. PseahPa - sea level pressure in hPa

14. PTnd - pressure tendency in hPa

15. Nt - total cloud cover

16. Nh - cloud cover by high-level cloud fraction

17. HKm - height of cloud base

18. InsoD1 - insolation in hours

19. Viskm - visibility in kilometres

20. Snowcm - depth of snow cover in centimetres

21. pr6 - precicipitation totals in 6 hours

22. pr12 - precicipitation totals in 12 hours

23. pr24 - precicipitation totals in 24 hours

24. TemperatureCAvg - average air temperature at 2 metres above ground level. Values given in Celsius degrees

25. TemperatureCMax - maximum air temperature at 2 metres above ground level. Values given in Celsius degrees

26. TemperatureCMin - minimum air temperature at 2 metres above ground level. Values given in Celsius degrees

27. TdAvgC - average dew point temperature at 2 metres above ground level. Values given in Celsius degrees

28. HrAvg - average relative humidity. Values given in %

29. WindkmhDir - wind direction

30. WindkmhInt - wind speed in km/h

31. WindkmhGust - wind gust in km/h

32. PresslevHp - Sea level pressure in hPa

33. Precmm - precipitation totals in mm

34. TotClOct - total cloudiness in octants

35. lowClOct - cloudiness by low level clouds in octants

36. SunD1h - sunshine duration in hours

37. PreselevHp - atmospheric pressure measured at altitude of station in hPa

38. SnowDepcm - depth of snow cover in centimetres

Arguments

interval

'daily' or 'hourly' dataset to retrieve - given as character

date

start and finish date (e.g., date = c("2018-05-01", "2018-07-01")) - character or Date class object. If not provided last 30 days are used.

coords

add geographical coordinates of the station (logical value TRUE or FALSE)

station

WMO ID of meteorological station(s). Character or numeric vector

precip_split

whether to split precipitation fields into 6/12/24h

allow_failure

logical - whether to proceed or stop on failure. By default set to TRUE (i.e. don't stop on error). For debugging purposes change to FALSE numeric fields (logical value TRUE (default) or FALSE); valid only for hourly time step

Examples

# \donttest{
  # downloading daily data for New York - La Guardia (last 30 days by default)
  new_york = meteo_ogimet(interval = "daily", 
                          station = 72503, 
                          coords = TRUE)
# }
