About

At a developer meeting held in the course of the ERAD2022 conference in Locarno, Switzerland, future plans and cross-package collaboration of the openradarscience community were intensively discussed.

The consensus was that a close collaboration that benefits the entire community can only be maximized through joint projects. So the idea of a common software project whose only task is to read and write radar data was born. The data import should include as many available data formats as possible, but the data export should be limited to the recognized standards, such as ODIM_H5 and CfRadial.

As memory representation an xarray based data model was chosen, which is internally adapted to the forthcoming standard CfRadial2.1/FM301. FM301 is enforced by the Joint Expert Team on Operational Weather Radar (JET-OWR). Information on FM301 is available at WMO as WMO CF Extensions and is described in the WMO Manual on Codes.

Any software package that uses xarray in any way will then be able to directly use the described data model and thus quickly and easily import and export radar data. Another advantage is the easy connection to already existing open source radar processing software.

Status

Xradar is considered stable for the implemented readers and writers which have been ported from wradlib. It will remain in beta status until the standard is finalized and the API as well as data model will move into stable/production status.

[!IMPORTANT]
Currently only polar (radial) and not cartesian or any other gridded radar data can be imported!

Features

Import/Export Capabilities

CfRadial1 and CfRadial2 — CF/Radial convention for radar data
ODIM_H5 — EUMETNET OPERA Data Information Model (HDF5)

Import-Only Capabilities

DataMet — DataMet weather radar
Furuno — Furuno weather radar
Gamic — GAMIC HDF5
HPL — Halo Photonics Lidar
IMD — India Meteorological Department
Iris — Vaisala IRIS/Sigmet
MRR — Micro Rain Radar (METEK)
NexradLevel2 — NEXRAD WSR-88D Level 2
Rainbow — LEONARDO (formerly Selex/Gematronik) Rainbow
UF — Universal Format

Data Transformation and Alignment

Georeferencing (AEQD projection)
Angle Reindexing
Format Transformation support to CfRadial1 and CfRadial2

[!NOTE]
All formats load into CfRadial2, so converting to CfRadial1 is seamless.
