Monitoring Stations Avaliability:

Pollutants Averages Compared To Legal Values:

Monitoring Gaps Alerts Detected:

Notes:

• This report integrates and calculates monitoring data from both the Israeli MoEP and Igud Arim Sharon-Carmel monitoring sites
• 'Clean Air Law' legal Air value max limits can be found here
  • Benzene Israeli Max allowed 24-Hours Average limit is 1.2 PPB
• For each monitoring station, Avaliability grade is calculated
  • On properly operated stations, measurements should be conducted once per 5 minutes, producing high Avaliability grade
• • Stations that do not monitor for more than 1-Hour will produce a Monitoring Gap Alert, For more than 4-Hours a broadcast email would be sent
• The pollutants averages table shows the legal limits defined in the Israeli law, compared to the level of pollutants form all monitored stations
  • Different pollutants have different averaging Time-Period defined by law, The report calculates averages in all relevant resolution, For example –
• • For Daily time period – Average of all the pollutant's values in the entire day is calculated
• • For Hourly time period, the average of each hour in the day is calculated separately, then the highest hourly average is chosen for display
• Each Pollutant 5-Minutes measurements >= 85% (Or 100% for PM25) Of lowest time resolution legal-limit will be shown as a Pollution Event Alert (Even though Israel legal standard might refer to daily average)
  • Pollution Event Alerts are meant to give an early warning in order to prevent violations of the daily legal limit – Not to wait for a full day of violations to occur before alerting the public
• • Alerts are defined for the following monitored pollutants (Bound to station limitations): Benzen, Toluen, PM2.5, PM10, NOX, NO2, SO2, O3
• • For each alerted pollutant, full-day graph will be generated (With legal limit marked as red line) and a broadcast email would be sent
• • For each Benzen alert, All other pollutants at the time of alert are also dispalyed, including pollutants direction trend (↗ ↘ Arrows calculated comparing current pollutant value to it's running average)
• For Benzen, Full-day graphs will always be generated (Even without alert), since as a worst-case BTEX indicator pollutant we would like be aware of even partial unusual increase
• Verbal description of the Pollutants Source Direction is calculated from wind data for each alert
  • Stations without wind measurements, Receive simulated average wind direction of nearby stations
• • Leviathan's direction to each monitoring station is displayed and can be compared to alerts directions
