Narrative:

We were preparing to begin our descent into rkd when brunswick approach informed us that according to the rkd AWOS conditions were below VFR. Brunswick instructed us to turn left to a heading of 220 degrees which was a vector for the localizer DME runway 3. At this point, we were VFR and could see the airport. We advised brunswick of the situation and then contacted our company. The agent in rkd who is a certified WX observer made a report of clear skies and 12 mi visibility. We then relayed the WX information to brunswick approach and then cancelled our IFR clearance. Upon landing in rko I questioned the agent as to the validity of the AWOS. He informed me the AWOS was placed a reasonable distance from the runway and very close to a small stream. The agent also informed me that routinely a small amount of fog will form close to the AWOS thus reducing the WX observations even though the airport itself is clear. It would seem to me that either the AWOS should be moved to a more realistic location or certified unreliable.

Narrative: WE WERE PREPARING TO BEGIN OUR DSCNT INTO RKD WHEN BRUNSWICK APCH INFORMED US THAT ACCORDING TO THE RKD AWOS CONDITIONS WERE BELOW VFR. BRUNSWICK INSTRUCTED US TO TURN L TO A HDG OF 220 DEGS WHICH WAS A VECTOR FOR THE LOC DME RWY 3. AT THIS POINT, WE WERE VFR AND COULD SEE THE ARPT. WE ADVISED BRUNSWICK OF THE SITUATION AND THEN CONTACTED OUR COMPANY. THE AGENT IN RKD WHO IS A CERTIFIED WX OBSERVER MADE A RPT OF CLR SKIES AND 12 MI VISIBILITY. WE THEN RELAYED THE WX INFO TO BRUNSWICK APCH AND THEN CANCELLED OUR IFR CLRNC. UPON LNDG IN RKO I QUESTIONED THE AGENT AS TO THE VALIDITY OF THE AWOS. HE INFORMED ME THE AWOS WAS PLACED A REASONABLE DISTANCE FROM THE RWY AND VERY CLOSE TO A SMALL STREAM. THE AGENT ALSO INFORMED ME THAT ROUTINELY A SMALL AMOUNT OF FOG WILL FORM CLOSE TO THE AWOS THUS REDUCING THE WX OBSERVATIONS EVEN THOUGH THE ARPT ITSELF IS CLR. IT WOULD SEEM TO ME THAT EITHER THE AWOS SHOULD BE MOVED TO A MORE REALISTIC LOCATION OR CERTIFIED UNRELIABLE.
