Those instructions for moving the station are incorrect and outdated.
To move your station, you simply send an email to cwop-support <at> noaa.gov and give them your new Latitude and Longitude in Decimal degrees and your elevation in meters. The elevation should be the elevation of your barometric sensor...not your anemometer. Be sure to remember to reference your CWOP station ID in your email.
But before you send that email you should be sure that your CWOP software is already uploading with the correct Latitude and Longitude for your new location.
And lastly you should also send an email to MesoWest (atmos-mesowest <at> lists.utah.edu) so that they also update their records for your CWOP ID.
If you need any more help regarding any of these things then just provide more information like the software you are using and what your locaiton is and what your CWOP ID is...etc. If you need help determining your elevation you should use the following website:
