Automated meteorological measurements from northern Snowdonia, particularly Snowdon Summit (1085m), are described and presented here for the first time. In particular, a long time series of radiative measurements has been acquired. Up‐ and down‐welling shortwave global solar irradiance and longwave irradiance, including surface reflectivity (albedo) from Snowdon Summit and the nearby site Marchlyn Mawr (660m) since 2004 are described and discussed.

Funding Information:
The project has been funded by NERC, STFC, Royal Meteorological Society, and is currently supported by the Royal Astronomical Society and Bristol University's Faculty of Engineering. Many students have worked on the project and their contributions are acknowledged. In particular, I. Said (Bristol University, MEng Aerospace Engineering) carried out the power analysis and A. Bale (Bristol University, MEng Engineering Mathematics) developed the website. N. Clifford, K. Long, R. Mackenzie, G. Quelch (Oxford Physics), C. Eley and J. Firth (RAL Space) provided technical support. S. Sinfield at First Hydro provided access to the Marchlyn Mawr site and support for the Snowdon Weather Stations Project. Snow data 1979–1994 was provided by C. Aron. The Snowdon Mountain Railway continue to generously provide free transport to the summit, hot drinks and WD40. 1
