FAA to Award Contract for ADS-B in the Gulf of Mexico
During
the first week of September, a contract for the FAA’s $110 million
ADS-B (Automatic Dependant Surveillance-Broadcast) will be awarded.
This system will enhance helicopter communications, which have been
non-existent across the NW Gulf, with GPS tracking used for flight
separation. Another positive note with this contract is the
placement of 25 to 30 AWOS (Automated Weather Observing Systems)
alongside the ADS-B system on selected platforms. Deployment of
ADS-B will begin in 2008. All weather systems will be deployed by
2009.
Battle Continues Between Pro and Anti Global Warming
Over
the last month, the NWS Cooperative Program has been under siege by
a group called Surfacestations.org, claiming that poor siting
standards of temperature equipment is the cause of higher
temperatures and a major contributor to global warming. To prove
this, they have trespassed on private property to attain photographs
of equipment, so all COOP sites should be aware of this group. A
link to the organization’s website can be found at:

Siting
Standards for Air Temperature Sensors:
·
Site
should be over level terrain (earth or sod) typical of the area
around the station.
·
Site
should be at least 100 feet from any extensive concrete or paved
surface.
·
All
attempts will be made to avoid:
o
areas
where rough terrain or air drainage are proven to result in
non-representative temperature data
o
areas
where water or drifting snow tends to collect
·
If the
sensor is within a shelter, position the shelter so it opens to the
north with the floor 4 to 6 feet above the surface. Shelters should
be located no closer to an obstruction than four times the height of
the obstruction.
·
In the
case of remote sensors not exposed in shelters, the air intake will
be 4 to 6 feet above the surface. Remote sensors should be located
no closer to an obstruction than four times the height of the
obstruction.
·
An object
will be considered an obstruction if the object is greater than ten
degrees in horizontal width as measured from the sensor and within
200 feet of the sensor.

Lake Charles public service staff will begin evaluating sites during
the upcoming fall and winter. In addition, Fisher-Porter rain gages
will be completely worked over and outside shells painted |
