WRF PR92 reference:

WRF was developed at the National Center for Atmospheric Research (NCAR) which is operated by the University Corporation for Atmospheric Research (UCAR). NCAR and UCAR make no proprietary claims, either statutory or otherwise, to this version and release of WRF and consider WRF to be in the public domain for use by any person or entity for any purpose without any fee or charge. UCAR requests that any WRF user include this notice on any partial or full copies of WRF. WRF is provided on an "AS IS" basis and any warranties, either express or implied, including but not limited to implied warranties of non-infringement, originality, merchantability and fitness for a particular purpose, are disclaimed. In no event shall UCAR be liable for any damages, whatsoever, whether direct, indirect, consequential or special, that arise out of or in connection with the access, use or performance of WRF, including infringement actions.

Other equations are independently implemented from published methods:

These methods define instantaneous diagnostics. LTG calibration was derived from
limited convective simulations; the fields are experimental proxies. PR92 uses
20 dBZ echo threshold and the entire imported domain. HDW here is instantaneous,
not the daily-maximum HDW climatological percentile.
