NWS Upper-air Observation Reliability Score

The Observation Reliability Score to used to help quickly identify National Weather Service upper-air stations with high numbers of missed flights and flights that did not reach 400 mb.

The score equation is simple: Score = (Flights not reaching 400 mb during the month) + (Missed flights during month x 3)

A perfect score equals ZERO.

Missed flights were given a heavier weight (3 times) since they have more of an impact to the upper-air program and NWS forecast operations.

Below are the ranked scores for the past 3 months and the 3 month average. Stations with a month to month score 5 or higher should be investigated by NWS Regional Office staff and station managers to determine what is causing the poor performance. If necessary, corrective actions will be taken to solve the problem(s).   It should be noted that there will be times when poor performance occurring during a month is caused by factors (e.g., lightning hit, installation of the new RRS) beyond the control of station staff.
