plotWFMetrics

[Mengxi-Wang]

Thank you very much for helping with the package update, it works now! But I have another issue today.

When I start using my own data (after quality filtering) to run plotWFMetrics, the picture seems strange. Some of the RHmetrics didn't show, and some shots even have no waveform, is that because of the data quality?

Could you please provide the number Orbit number and the shot number for one of those samples?

Are these cases where RHmetrics or shot display is abnormal because the default maximum waveform displayed in the code is less than the actual waveform peak? I guess.Thanks.

Could you please provide the number Orbit number and the shot number for one of those samples? Orbit number: O02179 shot number: 21790812100143302 result: Thank you!

Hi, Dr. Hamamura This problem were already fixed, but I still have a problem with the data quality! After I did quality filtering, if the waveform still looks strange, is that means the shot still not a good quality shot? Or it's because of some other technical problems? Kind regards, Mengxi

@Mengxi-Wang, the problem is probably with the data quality. The easiest way is to use l2b_quality_flag as a mask or else you would need to create an algorithm to check the quality. It is very common that over 90% have poor quality, it depends on climate conditions such as clouds, aerosols, solar radiance, surface reflectance, etc.

If you do find a shotnumber where the l2b_quality_flag == 1 but the plot is still messy please let us know, provide the orbit number and the shotnumber so we can inspect the problem.

Dear Caio,

Thank you very much for your reply!

I found the waveform of the same shot was different under the whole orbit and the subsetted orbit, I think it’s the index issue on L1B data. But will this act the same way in L2A L2B data? Will the rh metrics change when I only download several shots instead of the whole orbit?

Looking forward to your reply!

Kind regards, Mengxi

The shot_number should be globally unique and the same across all products, the subsetting should not affect the numbering nor the plotWFMetrics function.
