| Jan 25, 2022 at 2:42 | comment | added | JeopardyTempest | I think that it can be a real challenge to matching metar to climate reports (as metar will do 6/24 hour totals at 51ishZ [and not necessarily at midnight], whereas climo is midnight to midnight I believe). I'm not sure the answer... you could try contacting the director of wxchallenge.com where we often came to such an issue and see if he has any input on it. | |

| Jun 16, 2017 at 16:13 | comment | added | Robert McDonald | @KieranHunt In addition to a source for 0700-0700, I would be interested in your thoughts about how to interpret the values I've added (for hours 06 and 07) in the edit. | |

| Jun 16, 2017 at 14:22 | comment | added | user967 | @KieranHunt Can you source the 0700-0700 day? | |
| Jun 16, 2017 at 10:30 | comment | added | Kieran Hunt | They are 'hourly accumulations', i.e. the amount of rain that has fallen in the previous hour up to the labelled time. FWIW, the closest I can get to 3.3" for the source given is 2013-06-07 05:51 - 2013-06-08 05:51 (3.19"); not far off given the NWS defined rainfall day is 0700-0700. | |
