Issue # 3 - Corrected Canadian Data
DDWG Mailing list link:
http://lists.le.ac.uk/pipermail/darn-ddwg/2014-May/000050.html
Issue #3 relates to Canadian data that had incorrect first range parameters in the rawacf file.
This was corrected with a modification to the first range. Specifically, the parameters prm.lagfr and prm.frang were changed to 1500 and 225 respectively.
Below is a list of affected rawacf files. They have since been placed on the mirror as of April 25th 2014 and can be downloaded.
Update 8/04/2014
Additional files needing correction were identified by the Virginia Tech group and reported by Kevin Sterne. These files are only with Saskatoon (sas) and span between (and including) 20120201.00 to 20120331.22. Corrected files from this period have been posted on the mirror. The text file below has been updated with these filenames.
We are working on finding other possibly affected files and will advise.
Update 9/18/2014
Following a tangent discussion, the code that was used to fix the files here was posted to the DDWG listserv. These two files can be found in the supplemental materials below.
