Comparison of RAiDER and RADIATE

[whu-dyf]

I have used RAiDER and RADIATE to process the same data and observed a difference of approximately 14 mm between their results. Is there any article available that analyzes the performance of RAiDER?

Here is the link to the RADIATE software: https://github.com/TUW-VieVS/RADIATE.git

It seems that RADIATE results are closer to GNSS ZTD products than RAiDER.

Hi @whu-dyf sorry this has gone a bit stale but thanks for posting the comparison! The absolute delays RAiDER calculates will depend on the maximum integration heights used. It looks like the RAiDER differences are all around the same order of magnitude, which could mean a higher integration height is needed. Do you remember what height you used?

I used the same NWM data as input for Raider and Radiate. Both are ERA5 37 pressure levels. The maximum height is 1 hPa, if remember correctly.
