How To Use WOW

Viewing Weather Observations

To return to the homepage map, click on the WOW-IE logo in the top left corner.

The weather stations are indicated on the map. The Current Temperature values from the weather stations are the default element. Scientific rounding has been applied to all elements except rainfall rate on the map.

The filter options on the map shows 3 station types:

  • WOW Observations - observations from private weather stations and manual observations
  • Official Observations - National Meteorological Service weather stations
  • Registered Stations - all active and non-active weather stations

From the homepage click on the stations as indicated on the map or use the 'Weather Station Search' function with the station name or site ID. This will display its weather observation Summary and Weather Forecast pane. 'View Full Observation' gives a history of weather station data from that station.

The Observation tab displays the full list of weather observations from that station.

You can compare this data with another weather station, eg a nearby Official weather station.

View the latest observation on the 'Observation' tab.

To view a range of observations select the 'Table' tab to choose the start and end dates for the observations you wish to view and click 'Update'. The 'Graph' shows all the parameters selected. These can be unticked to view some separately.

Select 'Table' tab to view the listed table of 'Full Observations'. There can be more than one recorded observation from a station during an hour, for example the Met Éireann Automatic Weather Stations update twice an hour. The observations can also be viewed in spreadsheet format by clicking on 'Export' after setting the start and end dates.

Please note that the 'Search for a Location' function is only required when you wish to search observations for a different site from the one you initially selected.

 

Note: The WOW-IE map does not load stations correctly on the Safari browser.

All Registered Stations (Pending Observations)

This shows the locations of all weather stations that have been registered on the WOW database. They may appear as a black dot for the time period requested if they have not reported an observation for that time. Many weather stations do not report an observation until many minutes after the hour, use the Reset Map function regularly yo refresh for an update.

The Met Éireann Automatic Weather Stations update on the map at approximately 10 minutes past and again at 40 minutes past the hour. Most stations are active but please note some stations may be non-active.

Rainfall Rate

This is the maximum rainfall value recorded at a station in one minute during that hour and multiplied by 60 to give the hourly rate. Values less than the threshold are not reported.

Met Éireann's AWS and ACS

WOW-IE displays the observations from Met Éireann's Automatic Weather Stations (AWS) and Automatic Climate Stations (ACS). The values on the map come from the half hour report from each of those stations. Click View Full Observations - Data Display to obtain further raw observations.

Temperature, Wind Speed/Direction and Humidity element shows the average value for the last 10 minutes of each report, known to us as the '10-minute mean'. The Rainfall value comes from the highest 1-minute rain (mm) value in the half hour report and multiplied by 60 to obtain the hourly rate (mm/hr). The Rainfall Accumulation value displays the accumulated rainfall since that unit was reset, this is indicated in the Location Attributes - Reporting Hours section on each station's View Full Observations page. The AWS Pressure value is the last pressure value recorded (at station height) in each report.
