Agricultural Data Report

MÉ endpoint https://prodapi.metweb.ie/agriculture/report

This links to a file called report.json which contains Agricultural Meteorology Data for the past 7 days for a number of synoptic weather stations. The file is updated daily. Notes on the table All data are averaged or summed over the 7 day period A blank entry means that data were not available Normal means 30 year means from 1981 to 2010 Temp: Average Air Temperature and difference from normal in degrees C Rain: Total rainfall in mm and % of normal Sun: Total sunshine duration in hours and % of normal Soil: Average 10cm soil temperature in degrees C and difference from normal Wind: Average wind speed in knots and difference from normal Radiation: Total solar radiation in Joules/cm2 and % of normal

Station Details

MÉ endpoint: http://cli.fusio.net/cli/climate_data/webdata/StationDetails.csv

Details of all Met Éireann's rainfall, climate and synoptic weather stations, both open and closed. Details include: County, Station Number, Name, Height (m), Easting, Northing, Latitude, Longitude, Open Year, Close Year

  • There are loads of stations in this file. MÉ have 25 main stations. The Five airport ones are 'manned' and 20 others are automatic.

  • Because it's an easy way to make coordinates available for the main stations, I added "main": "true" to the 25 main stations.

  • Note Johnstown Castle, Roches Point, Sherkin Island & Mullingar have two stations, don't know which is correct but guessed the ones opened most recently.

  • Keys in the data have mostly been changed to camelCase though there are some inconsistencies
  • Wherever a key begins with a number, changed it to _number
  • All quotes on this page are from Met Éireann via data.gov.ie. and obviously all data is theirs to.
  • Please note that if you display any Met Éireann Live Text Forecast Data or data from the Forecast API on a webpage you must also display their weather warnings. Here's a link to download the licence.
