What's New?

1. No new clients at this time.

Improvements

1. Several end-to-end clients now utilize byte-range requests to download GRIB files.
2. Several end-to-end clients can now connect to Amazon Web Services (AWS) and Google Cloud as back-up data sources.
3. End-to-end clients that have multiple data sources can rotate to another server if there are server issues with the server the client was originally connecting to.

What Are Byte-Range Requests?

Specific variables at specific variables inside of a GRIB file are stored between a range of bytes (these byte-ranges are found in the GRIB Index Files). This methodology allows users to query for specific variables when there is no GRIB filter present (very helpful when downloading GRIB data from Amazon Web Services, ECMWF Open-Data and/or Google Cloud).

How Do Byte-Range Requests Help?

GRIB files are very large. Byte-range requests speed up download times and minimize traffic over the network.

WxData 1.7 Released

WxData 1.7

(C) Eric J. Drewitz 2025-2026

Documentation And Examples

WxData Documentation and Examples

What's New?

1. wxdata.client.byte_range_request() - A new raw client that performs byte-range requests on GRIB data. Byte-Range Requests minimize both download time and traffic over the network. This is very useful when there is no GRIB filter present. This is how users can subset a GRIB file by variables (String List) , levels (Float or Integer List), and level_type (String) when there is no GRIB filter present.

Improvements

1. Improved the aesthetics of the progress bars.

Bug Fixes

Nothing at this time.

What's New?

1. cfs_pressure() - An end-to-end client that downloads, pre-process and post-processes 6-hourly Climate Forecast System (CFS) data (for pressure-field variables).

2. cfs_flux() - An end-to-end client that downloads, pre-process and post-processes 6-hourly Climate Forecast System (CFS) data (for flux-field variables).

3. download_current_single_station_nexrad2_radar_data() - Downloads the latest NEXRAD II radar data for a user-specified radar site and returns a list of Py-ART radar objects corresponding to all the scans for a given radar.

4. download_current_multi_station_nexrad2_radar_data() - Downloads the latest NEXRAD II radar data for a user-specified list of radar sites and returns a list of Py-ART radar objects corresponding to all the scans for a given radar for all radars specified by the user.

5. get_aws_open_data() - A raw data client that allows users to download any publicly available data (data not hidden behind an API key) from Amazon AWS servers.

6. cfs_post_processing - A new module consisting of post-processors for CFS Pressure and CFS Flux data.

Improvements

Nothing at this time.

Bug Fixes

1. Fixed the xmACIS2 data client to handle invalid characters.

(C) Eric J. Drewitz 2025-2026

Documentation And Examples

WxData Documentation and Examples

What's New?

1. client.get_excel_data() - A new raw client to download and extract data from Excel files.
2. get_single_raws_station_weather_observations() - Client that downloads and returns observational weather data from a single user-specified RAWS station for a user-specified period of time.
3. get_single_raws_station_fuels_observations() - Client that downloads and returns observational fuels data from a single user-specified RAWS station for a user-specified period of time.
4. get_multi_raws_station_weather_observations() - Client that downloads and returns observational weather data for a list of user-specified RAWS stations for a user-specified period of time.
5. get_multi_raws_station_fuels_observations() - Client that downloads and returns observational fuels data for a list of user-specified RAWS stations for a user-specified period of time.
6. get_current_multi_raws_station_weather_observations() - Client that downloads and returns current weather observations for a list of user-specified RAWS stations.
7. get_current_multi_raws_station_fuels_observations() - Client that downloads and returns current fuels observations for a list of user-specified RAWS stations.
8. get_current_all_raws_station_weather_observations() - Client that downloads and returns current weather observations for all RAWS stations in a given state.
9. get_current_all_raws_station_fuels_observations() - Client that downloads and returns current fuels observations for all RAWS stations in a given state.
10. get_single_raws_station_weather_forecast() - Client that downloads and returns the latest 7-Day weather forecast for a single user-specified RAWS station.
11. get_single_raws_station_nfdrs_forecast() - Client that downloads and returns the latest 7-Day NFDRS (fuels) forecast for a single user-specified RAWS station.
12. get_multi_raws_station_weather_forecast() - Client that downloads and returns the latest 7-Day weather forecast for a list of user-specified RAWS stations.
13. get_multi_raws_station_nfdrs_forecast() - Client that downloads and returns the latest 7-Day NFDRS (fuels) forecast for a list of user-specified RAWS stations.
14. get_single_raws_station_meta_data() - Client that downloads and returns the meta-data for a single user-specified RAWS station.
15. get_multi_raws_station_meta_data() - Client that downloads and returns the meta-data for a list of user-specified RAWS stations.

Improvements

1. Completely refactored the FEMS module. The FEMS clients are now resilient to periodic variable name changes in the FEMS database. In FEMS, the meta-data is separate from the weather and fuels data. Any function that plots current observations correctly combines the latitude and longitude coordinates from the meta-data file into the Pandas.DataFrame that hosts the weather and fuels data, thus allowing users to plot this data on a map.

2. Added return_pandas_df=True as an optional argument to client.get_xmacis_data() for users who wish to download CSV files for multiple stations.

Bug Fixes

1. As stated in the improvements section, the FEMS clients are now resilient to periodic variable key changes in the FEMS database.
