In worldmet: Import Surface Meteorological Data from NOAA Integrated Surface Database (ISD)

worldmet (development version)

worldmet 0.10.2

Dependency Changes

• worldmet no longer depends on openair.

New Features

• 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").

Bug Fixes

• 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".

worldmet 0.10.1

New Features

• importNOAAlite() has gained the path argument, in line with importNOAA().

• importNOAAlite() now supports parallel processing using the {mirai} package, in line with importNOAA().

Bug Fixes

• importNOAAlite() can now import data from years other than 2025.

worldmet 0.10.0

New Features

• 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.

  • Due to this change, users are recommended to set 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.

worldmet 0.9.9

New Features

• The quiet argument of importNOAA() now also toggles the progress bar.

New Features

• getMeta() has gained the crs argument, which allows getMeta(lat =, lon =) to be defined using other coordinate systems.

Bug Fixes

• 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.

worldmet 0.9.6

New Features

• 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().

worldmet 0.9.5

Bug Fixes

• 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.

worldmet 0.9.4

Bug Fixes

• Fix precipitation. The 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.

worldmet 0.9.3

Bug Fixes

• Catch missing data error and report missing when importing data using importNOAA()

worldmet 0.9.2

New Features

• Exporting weatherCodes so that everything works when used by other packages through "explicit namespacing"" (e.g. worldmet::importNOAA()) without having to library(worldmet).

worldmet 0.9.1

Bug Fixes

• 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

worldmet 0.9.1

New Features

• 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}

worldmet 0.8.8

New Features

• 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)

Bug Fixes

• fix short WBAN codes.

• make sure all meta data are used and not only sites with most recent year

worldmet 0.8.4

New Features

• 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).

Bug Fixes

• fix bug when data not available for a year when using parallel processing

worldmet 0.8.0

New Features

• downloads now from webserver rather than ftp. Should be faster and allow more downloads. Thanks to Stuart Grange.

• add parallel processing using {foreach}.

worldmet 0.7.4

Bug Fixes

• don't use closeAllConnections().

worldmet 0.7.3

New Features

• default to downloading fresh meta data each time.

• update meta data.

Bug Fixes

• fix current year problem (base on meta data available in package).

worldmet 0.7.2

Bug Fixes

• make sure data are returned with NA when missing and not NaN.

worldmet 0.6

New Features

• Add ability to return precipitation measurements, if available.

• Add precipitation to exportADMS()
