In the API you will see Qcstaus and it will have a #1 behind it
-1 is the time is off on your weather station
Old thread but adding QC status for the sake of completion. My weather station and everyone around me has been at QC=-1 since the beginning of the year. I emailed WU and got a reply after 2 months.
Thank you for reaching out. QC status = -1 is not failing, it's not checked. It could be that there are insufficient comparable stations within a fixed geographic area for the analysis to be run. I don't know all the conditions that need to be met in order for the algorithm to be run, but that is the most common reason for a -1 to be produced.
Thank you for being part of the Weather Underground community!
