Back to basics: the met enclosure - an update
Strangeways, Ian
The original articles in this series were written over the period 1995 to 2005 (Strangeways, 1995, 1996a,b, 1998, 1999, 2000, 2001a,b, 2002a,b, 2003a,b,c, 2004, 2005). Of the 15 articles, in the 12-part series, 10 concerned traditional instruments, 2 were on automatic weather stations (AWSs), 2 on telemetry and one concerned data loggers. This first series was based on my work at the Institute of Hydrology (IH), now the Centre for Ecology and Hydrology (CEH), which included the design and development of some of the first AWSs and data loggers, and their evaluation on IH's traditional met enclosure. <br>The present article looks at how conventional sites have changed (or not changed), in the intervening years since the first set of articles, and at the increased use of electronic instruments. There are many thousands of met enclosures within the United Kingdom and across the world. Some will have changed in small ways, some considerably, some not at all, depending on the operator and the use of the data. For the purpose of this article, it is useful to look at specific examples of enclosures; that at the CEH, in Wallingford, is a good example of a typical modern met enclosure of professional standing and 60?years of operation. It is also known personally to the author, through long association. As it was also central to the first set of articles, it is appropriate to use it again here to demonstrate what has changed, and what has remained the same, since in this way 'like is compared with like'.<br>To introduce some diversity, the met enclosure at the Green-Templeton College in Oxford is also examined. Being one of the oldest enclosures anywhere, its present state is relevant and useful for the current discussion.</p>
