Hello -

I've just started measuring air temperature in my back garden and posting
the results to a website at http://www.sgurr.co.uk/nailsea/index.html

I'm curious about the shape of the graphs I'm getting, and whether I can use
the "spikyness" of them to tell me whether I'm shielding the temperature
sensor from the sun and the night sky well enough.

I fitted a larger sun shield about 2 weeks ago, and I'd appreciate any
comments on whether the previous-week graph now looks plausible, or whether
the spike on 18th April (for example) indicates the need for a better
shield.

Thanks
