worldmet no longer depends on openair.importNOAA() now recommends trying the other source if it fails to fetch data (i.e., if source = "delim" fails, the user will be prompted to try source = "fwf").Fixed source = "fwf" failing when importing data from closed stations.
Fixed source = "fwf" when hourly = TRUE and multiple sites are imported.
Removed present weather condition when source = "fwf".
importNOAAlite() has gained the path argument, in line with importNOAA().
importNOAAlite() now supports parallel processing using the {mirai} package, in line with importNOAA().
importNOAAlite() can now import data from years other than 2025.Parallel importing of NOAA data is now powered by {mirai}. This reduces the number of dependencies of {worldmet}, and also allows users to be more flexible with how parallel processing is achieved.
mirai::daemons() themselves. n.core will stil work for back-compatibility, but will give a once-per-session warning.getMeta() has gained the crs argument to search NOAA ISD stations by coordinates other than latitude and longitude.
Added importNOAALite() to access the ISDLite filestore.
Added the importNOAA(source=) argument to import ISD data from different file stores. This option can be useful if one of the file stores is not available for whatever reason.
All error and warning messages are now powered by {cli} and are more informative.
quiet argument of importNOAA() now also toggles the progress bar.getMeta() has gained the crs argument, which allows getMeta(lat =, lon =) to be defined using other coordinate systems.Fixed join problem due to {dplyr} updates.
Fixed spelling mistakes in weatherCodes
Converted the {worldmet} vignette to an article. This should ensure it is no longer reliant on NOAA's servers. It can now be accessed at https://openair-project.github.io/worldmet/articles/worldmet.html.
importNOAA() will now display a progress bar when multiple years of met data are to be imported.
Improved the formatting of the popups in getMeta() in line with openairmaps::networkMap().
Added the provider argument to getMeta(), allowing for users to define one or more leaflet basemaps. Uses the same default as openairmaps::networkMap().
exportADMS() now invisibly returns the input data, in line with, e.g., readr::write_csv().
do not add precip to exportADMS()
Cloud cover data mostly spans 1 to 8 Oktas and no zero (clear sky); use ceil_hgt = 220000 (unlimited) to indicate clear sky when cloud cover is reported as missing.
Do not use ftp for site information.
precip_12 gives the sum of the precipitation over the past 12 hours and the sum of this column should be the annual total in mm. precip spreads the 12-hour total evenly across the previous 12 hours. {worldmet} no longer tries to combine 12 and 6 hour totals.importNOAA()weatherCodes so that everything works when used by other packages through "explicit namespacing"" (e.g. worldmet::importNOAA()) without having to library(worldmet).fix bug when lat and lon provided in getMeta()
fix bug when several years are selected and columns are different lengths when n.core = 1
Significant changes due to NOAA storage formats and different storage locations
Remove options for precipitation and present weather in importNOAA(); just return everything
Return data as {tibble}
export getMetaLive() to allow users direct access to all meta data and easy re-use without re-downloading.
add option path to allow users to save met data as an rds file.
deprecate fresh option in getMeta().
Assume 9999 is missing for visibility (was 999999)
fix short WBAN codes.
make sure all meta data are used and not only sites with most recent year
query live meta data when using getMeta().
parallel processing for sites and years.
use readr::read_csv() for meta data (read.csv() seems very slow in R 3.4.3).
downloads now from webserver rather than ftp. Should be faster and allow more downloads. Thanks to Stuart Grange.
add parallel processing using {foreach}.
closeAllConnections().default to downloading fresh meta data each time.
update meta data.
NA when missing and not NaN.Add ability to return precipitation measurements, if available.
Add precipitation to exportADMS()
