Strong rainfall intensity in NIMROD data #4

Open LinHungMing opened 12 months ago

LinHungMing commented 12 months ago

output_39 output_567 output_588 I'm now trying this code to process NIMROD data. However, I wondered what' wrong in the data. As can be seen, some gathered pixels showed very strong rainfall intensity.

Sorry I don't know the answer to your question. It would be worthwhile to look at the header entries (you can use the query() method) for which sudden changes might indicate file data is corrupted. I have quite often seen frames where rainfall appears to suddenly not be present where there are errors in the gathering of the original measurements. However, rainfall events can be quite brief (so it would be difficult to detect a d filter out such errors) - worth considering if some of what you are seeing might be real events.
