vol2bird: Vertical profiling of biological scatterers from weather radar data

All issues included in this release can be found here.

• vol2bird now reads Vaisala Sigmet IRIS (Iris RAW) format, the native radar data format of Vaisala radar processors (e.g. used in Canada, Portugal, Finland) (#112)

• added functionality to vol2bird to read files containing single scans (sweeps) and merge them into polar volumes (#116)

• rsl2odim now converts Vaisala IRIS format and ODIM hdf5 format and can merge files containing scans / sweeps into a polar volume.

• new input argument format that allows specifying multiple input files

• change default maximum range from 25 km to 35 km (#117)

• fixed a bug that in rare cases produced a negative reflectivity eta (#123)

• new determineRadarFormat() function to check whether a file is in ODIM, IRIS or RSL format

• added a documentation webpage generated by doxygen (available at http://adokter.github.io/vol2bird)

• added this NEWS.md file to document releases
