It ought to be good.

Altitude 62 metres (unofficial)
Estimated Class 1, marginal ((7.6+212.4+3022.3)-325.9) / 31416 = 9.2% hardstanding or buildings within 100 metres. Note: only valid since 2004 (see text)
UHI, local, extending campus, lake (not typical of the area but artificial lakes after gravel extraction from alluvial beds are fairly common, or filled with rubbish), distance, town urbanising and urban sprawl towards London. There have been significant developments in and close to Reading since this station was built.
Money has poured into building so the situation before 2003 is unknown, nearest building looks new [Jim D has put a date on it, see comments]. A minor station move, 10 metres took place 2003/4, captured by Google images. A paved path and additional instruments were added to the site. The move has kept the Stevenson screen 10 metres from paving.
Images circa 2004 and 2004, exact dates not known but both summertime (leaves on trees)
Ongoing building is taking place, such as behind the building lower right here, see Google images. Maps for “Whiteknights campus” are here but seem out of date.

It seems unlikely the site was automatic when it started and given the distance from buildings a bit far for a daily walk. I have no idea of the history and site moves.
The site is an active AWS in the MIDAS database but no high res data seems public.
