August 21, 2019

Please refer back to my first post for site specifications.

Station:  Newcastle (Nobbys) 61055

Opened: 1862

But the screen has moved at least three times, from very close to the cliff edge to the present position.

1999 BOM site plan:

Newcastle Nobbys plan99

2001 site plan:

Newcastle Nobbys plan0107

The screen moved to the present location between 2007 and 2010.

The screen is close to a concrete path, a solid brick wall, pavement, and has moved from a more exposed to a less exposed position.

This station is not compliant, but temperatures are reported at Latest Weather Observations.    Unreliable temperatures from here are used to adjust data at Acorn sites.

But the station moved sometime in the last four years, probably from the house yard directly behind.  Here’s the old site plan:

Murrurundi plan2014

Here’s the street view from 2010 before the screen was installed just metres from an A/C unit.

The old site was non-compliant, and the station was moved to the new site at the Aged Care facility which is also non-compliant, being near an air conditioning unit, near a large building, a road and a carpark.

This station is not compliant, but temperatures are reported at Latest Weather Observations.    Unreliable temperatures from here are also used to adjust data at Acorn sites.

Here’s another station with an overgrown enclosure just two years ago- grass and scrub to one metre high (almost to the height of the screen)- and surrounded by scrub to 3 metres and trees to 8 metres.  It may have been tidied up since then, but the removal of offending scrub and trees would also introduce an artificial change to the site.

This station is not compliant, but temperatures are reported at Latest Weather Observations.    Unreliable temperatures from here are also used to adjust data at Acorn sites.

The screen and enclosure looks good in 2019 (as far as a satellite photo can tell), but in 2014 the BOM inspection revealed “high grass 0.5 to 1m inside enclosure”.  Remember Viewbank?   Grass is supposed to be trimmed to a few centimetres, but here on at least one occasion this station failed to comply with specifications for several months, as grass does not grow long overnight.  How often did this happen, at how many other sites?

This station is not compliant.  Temperatures are reported every minute at Latest Weather Observations. and used to adjust temperatures at Acorn sites.
