Temperature: Plots of instances where data failed qc tests.


Example of step test and spatial tests working well
Example of spatial test erroneously flagging Frasier
R. outflow case. It's notable that the step test did
not erroneously flag this event.
East side of mountains in cold air vs. APSW1 which must be
protected by the mountains from the cold air, causing
erroneous flagging

Case where very small changes in elevation (due to Columbia R.
Valley) cause big differences in temperature and probably
erroneous flagging

Case where small # of stations within radius of influence
combined with minimum st. deviation requirements makes
spatial test only catch this too-warm station on 3 hours

case for increasing minimum # of stations in radius required for
simple neighbor test?
case where I assume BUCKC is ok just because of it being towards
the eastside of the Cascades, but lots of obs as far east and quite
a bit colder.
Tough case to figure out for any spatial test (or human) with that 1 deg F obs next to the 25 deg F obs
Tough case to figure out for any spatial test (or human) with that 1 deg F obs next to the 25 deg F obs
Example of persistence test apparently working well,
although missing the first few hours of flat-lined obs
Example of a case when OK mesonet spatial test did not flag
any data but the simplified elevation/proximity test did.
Suspect step test flagging?
Good persistence test flagging
