Is anyone aware of open source radar software that will help simulate data from a particular wavelength using another? For instance, I’d like to simulate Ka-band retrievals from X-band data. Thanks.
Hi @afunk and welcome to openradar discourse!
First, I do not know of a full fledged data simulator which can simulate radar data at one frequency band by taking measured data from another frequency band. If there is, I’d be interested, too!
There are some papers which provide information for transformation of reflectivity from one band to another for different hydrometeors (snow, hail, rain):
- Ku to X: https://doi.org/https://doi.org/10.1038/s41597-022-01656-0
- Ku to S: https://doi.org/10.1002/jgrd.50138
- S to Ku: https://doi.org/10.1175/2008JAMC1974.1
These described transformations have been used to compare TRMM/GPM measurements to ground radars. The above coefficients are implemented in Data Transformation — wradlib as well as a utility function to calculate the polynomial.
In the wradlib documentation GPM/TRMM matching is described Match spaceborn SR (GPM/TRMM) with ground radars GR — wradlib.
As this might not fully answer your question I hope to that others can chime in with additional information.
Best,
Kai
Thank you Kai. I’ll take a look at the links.
