Raw Data I/O

Please have a look at the tutorial Data Input - Data Output for an introduction on how to deal with different file formats.

Xarray backends

Reading radar data into xarray Datasets using xarray.open_dataset and xarray.open_mfdataset.

Former available backends have been ported to xradar-package.

RadolanBackendEntrypoint

Xarray BackendEntrypoint for RADOLAN data.

Digital Elevation Model Data I/O

Provide surface/terrain elevation information from SRTM data

download_srtm	Download NASA SRTM elevation data Only available with login/password
get_srtm	Get NASA SRTM elevation data
get_srtm_tile_names	Get NASA SRTM elevation data tile names

GDAL Raster/Vector Data I/O

open_vector	Open vector file, return gdal.Dataset and OGR.Layer
open_raster	Open raster file, return gdal.Dataset
read_safnwc	Read MSG SAFNWC hdf5 file into a gdal georeferenced object
gdal_create_dataset	Creates GDAL.DataSet object.
write_raster_dataset	Write raster dataset to file format
VectorSource	DataSource class for handling ogr/gdal vector data

HDF Data I/O

Former available xarray based code has been ported to xradar-package.

open_gpm_dataset	Reads GPM files version V07A.
read_generic_hdf5	Reads hdf5 files according to their structure
read_opera_hdf5	Reads hdf5 files according to OPERA conventions
read_gamic_hdf5	Data reader for hdf5 files produced by the commercial GAMIC Enigma V3 MURAN software
to_hdf5	Quick storage of one <data> array and a <metadata> dict in an hdf5 file
from_hdf5	Loading data from hdf5 files that was stored by to_hdf5
read_gpm	Reads GPM files for matching with GR
read_trmm	Reads TRMM files for matching with GR

IRIS/Sigmet Data I/O

Reads data from Vaisala’s IRIS data formats. Former available code was ported to xradar-package and is imported from there.

IRIS (Vaisala Sigmet Interactive Radar Information System)

See M211318EN-F Programming Guide ftp://ftp.sigmet.com/outgoing/manuals/

Reading sweep data can be skipped by setting loaddata=False. By default, the data is decoded on the fly. Using rawdata=True the data will be kept undecoded.

read_iris	Read Iris file and return dictionary.
IrisProductFile	Class for retrieving data from Sigmet IRIS Product files.
IrisCartesianProductFile	Class for retrieving data from Sigmet IRIS Cartesian Product files.

Miscellaneous Data I/O

write_polygon_to_text	Writes Polygons to a Text file which can be interpreted by ESRI ArcGIS's "Create Features from Text File (Samples)" tool.
to_pickle	Pickle object <obj> to file <fpath>
from_pickle	Return pickled object from file <fpath>
get_radiosonde	Download radiosonde data from internet.
radiosonde_to_xarray	Convert Radiosonde Data to xarray.Dataset.
get_membership_functions	Reads membership function parameters from wradlib-data file.

NetCDF Data I/O

Former available xarray based code has been ported to xradar-package.

read_edge_netcdf	Data reader for netCDF files exported by the EDGE radar software
read_generic_netcdf	Reads netcdf files and returns a dictionary with corresponding structure.

RADOLAN and DX Data I/O

Reading DX and RADOLAN data from German Weather Service

Warning

Additionally to the binary composite formats DWD also provides data in ASCII format, which have a very limited header and need to extract product and datetime from the filename. Use on your own risk.

open_radolan_dataset	Open and decode a RADOLAN dataset from a file or file-like object.
open_radolan_mfdataset	Open multiple RADOLAN files as a single dataset.
read_dx	Data reader for German Weather Service DX product raw radar data files.
read_radolan_composite	Read quantitative radar composite format of the German Weather Service
get_radolan_filehandle	Opens radolan file and returns file handle
read_radolan_header	Reads radolan ASCII header and returns it as string
parse_dwd_composite_header	Parses the ASCII header of a DWD quantitative composite file
read_radolan_binary_array	Read binary data from file given by filehandle
decode_radolan_runlength_array	Decodes the binary runlength coded section from DWD composite file and return decoded numpy array with correct shape

Rainbow Data I/O

Reads data from Leonardo’s Rainbow5 data formats. Former available code was ported to xradar-package and is imported from there.

read_rainbow reads all data and metadata into a dictionary. Reading sweep data can be skipped by setting loaddata=False.

read_rainbow

Reads Rainbow files according to their structure

Xarray based Data I/O

Note

The Xarray backend code has been moved to xradar-package.

WradlibVariable

Minimal variable wrapper.
