I decided to check what BoM temp data there was for Nowra – just south of the Shoalhaven River south of Wollongong in NSW.
I found there is an ancient Nowra Council Offices 68105 which has data from ~1912 to ~1934 with gaps then nothing at Nowra.
WW2 increased activity at the HMAS Albatross Navy airfield a bit S of Nowra and BoM started max n min t from 1956 for – Nowra Ran Air Station
68076. Then in year 2000 I assume it changed to AWS as Nov 2000 was the last month for 68076 and Nowra Ran Air Station AWS 68072 the current station started with Nov 2000 the first full month.
So BoM monthly data tables at CDO imply there was only a one month overlap in switching to AWS.
I downloaded the data from CDO and pasted to a spreadsheet and I was surprised at the large increase in both max & min readings for Nov 2000 in AWS over what I assume was liquid in glass thermometer.
I emailed what I had found to an expert in BoM data and he reported that there were only a few days data in Nov 2000 to make the presumed overlap. You could not make this up.
The relevant four links are below and just now the BoM pages will not show the daily data for me.
I have not tried looking at either “siteinfo” pdf yet.
What do readers think about BoM not doing a decent overlap (several years?) at this site where staffing could not have been an issue. Links below to monthly data at BoM CDO (Climate Data Online)
