>200m elevation bins profiles are missing

[ghost]

Hello, I have noticed that there is no data available for frabb radar for the elevation bins above 200m for the end of Nov (24-30), Dec 2017, Jan 2018. I was wondering why these data are missing and is there a way for me to obtain them? Thank you

Indeed, the data files are available, with data for elevations 0 and 200, but NA for all the rest. @adokter, any idea why higher elevations have no data?

library(bioRad)
vp <- bioRad::readvp("frabb_vp_20171201T0045Z_0x7.h5")
vp$data

I received reply from Meteo France. They have complete data (all elevation bins) in their archives for this time period, and I was advised to contact SMHI. Do you know whom I should address at SMHI? Thank you

[peterdesmet]

Issue regarding @apnest not getting access to the data is resolved. What remains is that the upper bins are cut off in the FR data on the repository. @adokter is that a processing or data input issue?

[adokter]

Regarding @apnest issue (Anna Nesterova), we have asked Gunther Haase at SMHI what might be the problem, he wrote on Sep 3 that he is looking into it. The problem has been fixed since Feb 12, but the data from Nov 24 2017 - Feb 12 2018 contain only data for the lowest elevations. This has likely been a problem at Baltrad, and the profiles will have to be reprocessed by someone.

Email to Gunther below for future reference:

I just noticed there are no profiles being generated for Finland since 12 February 2018 - does any of you know what may be the cause?

Probably related to this, the French profile data contain garbage from Nov 24 2017 - Feb 12 2018. I therefore suspect something was changed in the pipeline on Feb 12, which fixed a problem for France, but introduced a problem for Finland. Potentially this is related to the merging of scans into volumes at Baltrad.

Gunther/Liesbeth, any idea what is going on and whether there is an easy fix. Would be nice to have Finland running again with migration starting.

I am currently waiting for the raw data for frabb that Gunther Haase kindly agreed to send me. Once I have it, I will be happy to reprocess frabb data for Nov 24 2017 - Feb 12 2018 period.

Nice, thanks!
