Climatology

A paper describing the calibration of the long temperatures series (1795-2003) from Armagh Observatory was accepted for publication by the International Journal of Climatology. Further papers on the soil temperature, pressure and humidity series are in preparation.

One of the remaining uncertainties in the temperature series, namely the correction for exposure resulting from the move from a north wall screen type of exposure to a Stevenson Screen in 1885, was cleared up by a series of continuous temperature readings from both locations throughout the year. The results showed that there was a very small (less than 0.2C) difference in the mean temperature between the two locations, in spite of the close proximity of the north wall screen to the Observatory and the installation of central heating in parts of the building. The corrections applied were practically identical to corrections derived from data supplied by the Valentia Observatory where a similar situation existed.

The large amount (over 1000 documents) of meta-data concerning the Armagh climate site has been catalogued and scanned digitally. This material is of the utmost importance for future studies of the Armagh climate series which, now that they are standardised, receive more and more attention by climatologists.
