One of the biggest problems with this system is the Ceilometer.Its purpose is to determine cloud base height.
But it's not movable, where the older manned system, the weather technician could rotate the radar to a heading and then roll the instrument up from ground level, looking out many miles, to any angle up to 90 degrees and determine cloud height for clouds several miles away from the airport, and report them.
The automated system has to wait until the clouds are overhead to measure them, and doesn't "see" them as they approach.
It's very dangerous to all who depend upon the accuracy of the weather information for the airports they are used at.
You can also look at All Weather Inc’s Automated Weather Observing System (AWOS), but they're not any better.
These systems are dangerous and they're getting people killed!
You just cannot replace a human being using human logic and doing the job.
