There has been a longstanding issue with IRIS in the decoding of cooperative observation (COOP) min/max temps with many tickets opened over the years.
Problem: When it comes to temperature data from cooperative observations, only the current temp is recorded in the IRIS database; the min/max reports from the RR3 are not saved into the IRIS database.
Desired Solution: Cooperative Observer min/max temps are recorded in the IRIS database so that they appear when running a min or max temp query.
For example:
#5057 - Opened 2014; Closed (Resolved - reported fixed in 5.0.1)
#6501 - Opened 2015; Closed (Resolved - reported fixed in 5.0.2)
#6546 - Opened 2015; Closed (Resolved - reported fixed in 5.0.2)
#19123 - Open 2016; Closed (Resolved - reported fixed in 6.1.1)
#22158 - Opened 2016; In-Progress, last updated 9 months ago (Target: 7.0.0)
#22159 - Opened 2016; Closed (comment that it appeared to be working 4 years ago, so ticket was closed)
#35579 - Opened 2017; New/Open (Target: 7.0.0)
#50539 - Opened 2018; Marked Complete over 1 year ago
#86166 - Opened 10 days ago; New/Open
While these tickets vary, generally the root cause is that the min/max temps aren't being saved. From reading discussions over the years I believe processing this data is complicated because co-op obs can arrive at any time of day (i.e. there are some observers who report min/max temp ending at 00z, or some other local time - they do not all report at 12z, and this varies across timezones and DST). However, previous tickets certainly seem like this issue has previously been solved. Is there a solution in the works for 7.0.0. for this problem? We would really like to see our cooperative observers in a min temp listing because they're often the coldest spots in the area.
