Each file contains a year of monthly average grids on a 1km Irish Grid Easting and Northing coordinates, presented in CSV format. The monthly rainfall totals are given in units of millimetres (mm) and minimum, maximum and mean air temperatures are given in degrees Celsius (°C).
Methods for estimating monthly rainfall amounts and temperatures for Ireland on a 1km grid were developed using point based data from approximately 500 rainfall stations and from over 80 temperature stations. The interpolation techniques weight the surrounding measured values to derive estimates for unmeasured locations. The number of stations varies each year, as stations open and close. The stations are operated and maintained by Met Éireann.
For long-term climatology, please head to www.met.ie/climate/30-year-averages and use the 30-year Normals available. For long-term climate change assessments, the World Meteorological Organisation (WMO) recommends the 1961-1990 Normals, otherwise please use the Climatological Standard Normals 1991-2020.
