What you will find is that the obs may be done by SAMOS (semi automatic met observation system) which is confirmed/validated or amended by a met observation trained ATSA (assistant) and not the ATCOs. This is standard practice across most NATS units. EGLC have the ATCOs verifying the SAMOS.
These observations are forwarded to the centrak met office out of which they create the forecasts.
Use of official met staff is too expensive!!
