A PILOT APCHING CEC WAS DENIED AN INSTRUMENT APCH BY ATC BECAUSE THE AWOS SYSTEM REPORTED WX WAS BELOW MIN. THE ARPT WAS VFR SO THE REPORTER RPTR CANCELLED IFR AND LANDED.

Narrative

I WAS IN VFR CONDITIONS. THE ASOS AT CEC WAS CALLING 3/4 MI VISIBILITY; 100 FT CEILING. THE ASOS IS WRONG A LARGE AMOUNT OF THE TIME. IT IS BY THE BEACH END OF THE ARPT AND FOG COVERS IT AND THE RWY IS OPEN. I ASKED ZSE FOR AN APCH AND WAS TOLD IT WAS TOO LOW AND SHE WAS UNABLE. I SAID THE RWY WAS OPEN AND; COULD I GET THE CONTACT OR A SPECIAL IN THERE? SHE SAID NO. I THEN SAID AGAIN THE RWY IS OPEN AND WAS TOLD TO SQUAWK VFR 1200 HAVE A GOOD DAY. SO I LANDED. THIS PROB WOULD BE SOLVED IF THE UNICOM OR OTHER LIVE WX RPTING WAS AVAILABLE THERE. A SECOND ASOS AT THE OTHER END OF THE RWY WOULD HELP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT WHILE THE AWOS DETECTION SYSTEM MAY HAVE BEEN REPORTING ACCURATE WX IT IS ALSO NOTORIOUSLY INACCURATE. IN THIS CASE; THE EAST END OF THE ARPT WAS VFR. THE ATC CTLR'S DENIAL OF AN INSTRUMENT APCH SEVERAL TIMES LED THE REPORTER TO CANCEL IFR AND PROCEED VFR TO LAND WITH NO PROBLEM. THE REPORTER SUGGESTED ALLOWING AN FBO OR OTHER ON ARPT PERSON TO GIVE WX ADVISORIES WHEN THE ARPT IS MANNED.
