Sunset at the Chilton site

The Chilton site

Latitude 51.70 N
Longitude 358.67 E

The Chilton ionosonde is located at the Rutherford Appleton Laboratory In Oxforshire. This instrument is a Lowell Digisonde, DPS1 and it continues the sequence of soundings started in Slough in 1931. In order to make sure that the change of site did not affect the data sequence, operation of both the Chilton and Slough ionosondes was carried out for over a year. Both data sets were compared, and the results of this comparison can be found by following the link below. The Slough site closed in 1995.
