Any meteorological (aka SYNOP) station working under the World Meteorological Organizaton (WMO) framework after year 2000 should be accessible. - **meteo_imgw()** - Downloading hourly, daily, and monthly meteorological data from the SYNOP/CLIMATE/PRECIP stations available in the dane.imgw.pl collection. It is a wrapper for `meteo_monthly()`, `meteo_daily()`, and `meteo_hourly()` - **meteo_noaa_hourly()** - Downloading hourly NOAA Integrated Surface Hourly (ISH) meteorological data - Some stations have > 100 years long history of observations - **sounding_wyoming()** - Downloading measurements of the vertical profile of atmosphere (aka rawinsonde data) ### Hydrological data - **hydro_imgw()** - Downloading hourly, daily, and monthly hydrological data from the SYNOP / CLIMATE / PRECIP stations available in the danepubliczne.imgw.pl collection. It is a wrapper for `hydro_annual()`, `hydro_monthly()`, and `hydro_daily()` ### Auxiliary functions and datasets - **stations_ogimet()** - Downloading information about all stations available in the selected country in the Ogimet repository - **nearest_stations_ogimet()** - Downloading information about nearest stations to the selected point available for the selected country in the Ogimet repository - **imgw_meteo_stations** - Built-in metadata from the IMGW-PIB repository for meteorological stations, their geographical coordinates, and ID numbers - **imgw_hydro_stations** - Built-in metadata from the IMGW-PIB repository for hydrological stations, their geographical coordinates, and ID numbers - **imgw_meteo_abbrev** - Dictionary explaining variables available for meteorological stations (from the IMGW-PIB repository) - **imgw_hydro_abbrev** - Dictionary explaining variables available for hydrological stations (from the IMGW-PIB repository) ## Examples Examples shows application of climate package with additional use of tools that help with processing the data to increase legible of downloaded data. - [dplyr](https://CRAN.R-project.org/package=dplyr) - [tidyr](https://CRAN.R-project.org/package=tidyr) ### Example 1 Finding a 50 nearest meteorological stations for a given coordinates in a given country(ies): ``` {r stations , eval=T, fig.width=7,fig.height=7, fig.fullwidth=TRUE} library(climate) ns = nearest_stations_ogimet(country = c("United Kingdom", "France"), point = c(-3, 50), no_of_stations = 50, add_map = TRUE) ``` ``` {r stations-2, eval=T} if (is.data.frame(ns)) { knitr::kable(head(ns, 15)) } ``` ### Example 2 Summary of stations available in Ogimet repository for a selected country: ``` {r stations-3, eval=T, fig.width=7, fig.height=7, fig.fullwidth=T} library(climate) PL = stations_ogimet(country = "Poland", add_map = TRUE) if (is.data.frame(PL)) { knitr::kable(head(PL)) } ``` ### Example 3 Downlading hourly meteorological data from Svalbard (Norway) for year 2016 using NOAA service ```{r noaa_svalbard, include=FALSE} df = readRDS(system.file("extdata/vignettes/svalbard_noaa.rds", package = "climate")) ``` ``` {r windrose,eval=F} # downloading data with NOAA service: df = meteo_noaa_hourly(station = "010080-99999", year = 2016) # You can also download the same (but more granular) data with Ogimet.com (example for year 2016): # df = meteo_ogimet(interval = "hourly", # date = c("2016-01-01", "2016-12-31"), # station = c("01008")) ``` ``` {r noaa-kable,eval=T} knitr::kable(head(df)) ``` ### Example 4 Downloading atmospheric vertical profile (sounding) for Łeba, PL station: ```{r sonda-read, eval=T, include=F, echo=F} library(climate) data("profile_demo") df2 = profile_demo[[1]] colnames(df2)[c(1, 3:4)] = c("PRESS", "TEMP", "DEWPT") # changing column names ``` ```{r sonda, eval=F, include=T} profile_demo <- sounding_wyoming(wmo_id = 12120, yy = 2000, mm = 3, dd = 23, hh = 0) df2 = profile_demo[[1]] colnames(df2)[c(1, 3:4)] = c("PRESS", "TEMP", "DEWPT") # changing column names ``` ```{r sonda2, echo=FALSE} knitr::kable(head(df2, 10), caption = "Exemplary data frame of sounding preprocessing") ``` ### Example 5 Preparing an annual summary of air temperature and precipitation using **dplyr** syntax for 10-years period (1991-2000) ```{r imgw_meteo, include=FALSE} df = readRDS(system.file("extdata/vignettes/leba_monthly.rds", package = "climate")) ``` ```{r imgw_meteo-2, eval=FALSE, include=TRUE} library(climate) df = meteo_imgw(interval = "monthly", rank = "synop", year = 1991:2000, station = "ŁEBA") # please note that sometimes 2 names are used for the same station in different years ``` ```{r imgw_meteo-3, fig.width=7, fig.height=7, fig.fullwidth=TRUE, error=TRUE, eval=TRUE, include=TRUE} suppressMessages(library(dplyr)) df2 = dplyr::select(df, station:t2m_mean_mon, rr_monthly) monthly_summary = df2 %>% dplyr::group_by(mm) %>% dplyr::summarise(tmax = mean(tmax_abs, na.rm = TRUE), tmin = mean(tmin_abs, na.rm = TRUE), tavg = mean(t2m_mean_mon, na.rm = TRUE), precip = sum(rr_monthly) / n_distinct(yy)) monthly_summary = as.data.frame(t(monthly_summary[, c(5, 2, 3, 4)])) monthly_summary = round(monthly_summary, 1) colnames(monthly_summary) = month.abb ``` ```{r imgw_meteo2, echo=FALSE, error=TRUE} knitr::kable(head(monthly_summary), caption = "Exemplary data frame of meteorological preprocessing.") ``` ### Example 6 Calculate the mean maximum value of the flow on the stations in each year with **dplyr**'s `summarise()`, and spread data by year using **tidyr**'s `spread()` to get the annual means of maximum flow in the consecutive columns. ```{r data, eval=TRUE, include=FALSE, echo=FALSE} h = readRDS(system.file("extdata/vignettes/hydro_monthly.rds", package = "climate")) ``` ```{r data-2, eval=FALSE, include=TRUE} library(climate) library(dplyr) library(tidyr) h = hydro_imgw(interval = "monthly", year = 2001:2002, coords = TRUE) ``` ```{r data-3, eval=TRUE, include=TRUE, echo=TRUE} knitr::kable(head(h)) ``` ```{r filtering, eval=TRUE, include=TRUE} h2 = h %>% dplyr::filter(idex == 3) %>% dplyr::select(id, station, X, Y, hyy, Q) %>% dplyr::group_by(hyy, id, station, X, Y) %>% dplyr::summarise(annual_mean_Q = round(mean(Q, na.rm = TRUE), 1)) %>% tidyr::pivot_wider(names_from = hyy, values_from = annual_mean_Q) knitr::kable(head(h2)) ``` ```{r filtering2, echo=FALSE, eval=FALSE} knitr::kable(head(h2), caption = "Exemplary data frame of hydrological preprocesssing.") ``` ## Acknowledgment Ogimet.com, University of Wyoming, and Institute of Meteorology and Water Management -
