Description:
Long-Term Averages (LTA) or Climate Normals are 30-year averages of weather elements. They are used to describe the current climate and to place current weather in context. Met Éireann has produced a suite of LTAs covering the period 1981-2010, which have replaced the 1961-1990 LTAs for day-to-day comparison purposes. LTAs of monthly rainfall and days of rain greater than or equal to 0.2mm, 1mm and 10mm have been compiled for over 750 locations. Using these data and data for Northern Ireland, provided by the United Kingdom Meteorological Office, gridded values have been produced at resolution of 1km2. This paper details the process involved in generating the new LTAs, from data collection through the network of rainfall observers, to quality control and estimation of missing values, and finally, the geostatistical methods used to produce the gridded datasets. A comparison is also made between the LTAs for 1961-1990 and 1981-2010, which shows an increase of approximately 6% in Average Annual Rainfall, and other seasonal and monthly changes
