"One man's junk is another man's treasure......"
The IP after takeoff was the ARM Central Facility at Lamont, OK.
At about 15 minutes prior to reaching the CF site, the site was contacted
by vhf radio. The CF site reported slear skies, but gave a report that the
Hillsboro, KS site had a Sc deck with a ceiling of about 3000 ft. The
decision was made ot proceed on to the Hillsboro Boundary Facility site to
perform the ARM Cloudy mission.
When we initially arrived at the Hillsboro site, there was a Sc
layer with a ceiling of about 3000 ft. We set up for tracks of 020 to 200.
Almost immediately the clouds became broken and at times scattered.
Thirteen legs were performed below, within, and above the cloud tops.
Although the mission plan called for three flight levels within the cloud,
only a single flight level was able to be achieved due to the relative
shallow cloud layer.
Towards the end of the thirteen leg mission, ATC problems were
encountered for IFR clearances. This can probably be an expected problem
for future ARM Cloudy missions.
The aircraft landed in OKC at 2307 UTC consuming 4.2 ARM hours.
