The Climatological Observers Link was founded in 1970 by a small group of amateur meteorologists and is the enthusiasts' weather observer network for the United Kingdom.

Every month since then a bulletin detailing the weather has been produced.


NEW PUBLICATION - orders now being accepted

Details and order form for this limited edition publication.


NEW in 2010. The first 40 years-worth of COL Bulletins are now available on a single CD for just £25. Beginning with 48 reporting stations in issue 1 (May 1970), the Bulletin has steadily grown in size over the years - and now contains typically 40-48 A4 pages with data from about 300 stations.

This CD contains over 500 issues of the Bulletin - essential reading if you're interested in re-discovering UK weather of the past 40 years!

Payment to 'Climatological Observers Link' - available from 16 Wootton Way, Maidenhead, Berkshire SL6 4QU.


Membership

COL membership is open to anyone with an interest in the weather.

The organisation caters mainly for amateur meteorologists, but the membership also includes many professionals and observers from other bodies, eg schools, universities and research establishments.

Many of our members run weather stations that co-operate with the Met Office and other organisations, but you don't have to run a weather station to be a member. COL has no age limits - members range from the teens to the quite senior, the current total being over 400.

The distribution of membership is also quite widespread. The majority of members currently reside within the United Kingdom, but a growing number of other countries are represented, ranging from many European countries to others as far afield as Australia.

Monthly Bulletin

Each monthly issue contains

  • a synopsis of the previous months' weather
  • extensive columns of data from about 350 reporting stations, including information on:
    temperature (air and ground), precipitation, sunshine
    number of days with snow, fog, thunder, etc.
    wind, cloud cover
  • monthly articles on
    thunder activity, optical phenomena, snowfall
  • information on:
  • a station details section, where notable events and records are described
  • daily temperature, precipitation and sunshine data from about 12 sites scattered across the British Isles
  • monthly mean surface pressure map for the British Isles, and anomaly maps for temperature, precipitation and sunshine
  • details of newsworthy weather events from around the world
  • letters and correspondence from COL members
Each monthly volume contains about 44 A4-sized pages and, at the end of the year, an annual summary edition is produced. Monthly issues are published by about 20 days after the end of the month in question.

COL Directory

In an attempt to assist members to keep in touch with each other and find common interests, a Directory has been published at intervals. The Directory contains a brief history of COL, full details of the membership and, for each operating station, also includes the site location, times of observation, equipment in use, length of site records, site details and the observers particular interests in meteorology.

The latest version, updated November 2007, is written on a cd-rom and contains photographs of member's weather stations.

Advertising

COL is able to carry adverts in its monthly Bulletin. For further details, please contact the Editor.

Bulletin Data

Being an amateur-based organisation, it is difficult to lay down stringent standards of accuracy for data submitted to and published in the bulletin. Any climatic station, whether amateur or professional, is likely to have some aspects peculiar to that site. We believe the general standard of COL stations to be high, indeed, many are approved by local meteorological offices/national weather services.

However, all COL stations are graded according to their equipment and exposure. In addition members are asked to adhere as closely as possible to our observing/reporting protocols.

Subscription Rate

COL is a non-profit making organisation, run by enthusiasts for enthusiasts. As a result we endeavour to keep subscriptions rates as low as we can.

Current rates can be found here

COL daily weather diary

The COL daily weather diary forms an important part of each monthly bulletin, and contributions are always welcome for inclusion in this from any source.

Station averages

Late in 1996 COL published a 200-page A4 booklet containing averages for the periods 1961-70, 1971-80, 1981-90 and 1961-90 at almost 200 of its observing stations. The booklet contains information on averages and extremes of temperature, rainfall, sunshine, snow, frost, thunder and hail. Most of the data refer to the periods 1971-80 and 1981-90. The booklet may be purchased for £14 incl p&p.

During 2001 COL produced a booklet of averages for the period 1971-2000 containing monthly values of sunshine, rainfall and temperature. These averages were used in the Bulletin until 2011, and may be purchased for £6 incl p&p.

From 2011 COL has been using averages for the period 1981-2010. A comphensive book containing these averages, those for the period 2001-2010 - along with extreme values for both periods - is now available. See here for more details - and for information on how to purchawse your own copy which is available to members and non-members.
