I downloaded PERSIANN-CCS for the region of Pawlowdar, Kazakhstan and this has stripes all over my downloaded data.
For another AOI in Kazakhstan I do not have this problem.

Does anyone of you have any idea where these artefacts are coming from?
I did not process the data at all.

The Further reading link brings you to The PERSIANN System Fine Resolution Precipitation Estimates Using PERSIANN-Cloud Classification System which shows that the data is merged with signals coming from both geostationary and polar/near polar satellites. My guess is that it's just banding in one of these datasets (probably from that second group of satelites).

I tried to look at raw image data from these satellites (to illustrate my assumption), but I bump into sites that are affected by the current US government shutdown, resulting in e.g. incorrect and expired CSS certificates.

If you can dig up these raw images in a later stage, you'll probably be able to map the width of those bands to the aperture of the satellite.

  • $\begingroup$ Thanks a lot for you effort so far @Jan Doggen! that is my guess as well, that i have got the stripes in the data because of poor merging techniques applied. At the moment i am in contact with the provider of the PERSIANN-CCS data. I will keep you informed on updates! /b $\endgroup$ – ExploreR Jan 21 at 9:15
  • $\begingroup$ note: when i am just visualising the data on URL:chrsdata.eng.uci.edu I do not have these stripes. $\endgroup$ – ExploreR Jan 21 at 9:28
