Presentation and Reporting
Conclusion
Data Viewing
Data received from real-time monitoring
systems should be viewed regularly
Dedicated teams of experts will have to monitor
the data 24X7
Daily, Weekly, Monthly and Yearly data trends
should be viewed to ensure correct data is
being generated and transmitted
If irregularities in the data is found then
verification of the monitoring systems is
required.
Hourly Data
24 Hourly Data for a Week
Monthly Data
Monthly Data for July 2014
Very high 24 hourly avg. values,
needs verification
No Data
System Verification
Checking of system ALARMS
No Alarms generated
System Verification
Checking the diagnostics of the instrument
SO2 diagnostics is ok…..
System Verification
Remote Calibration
• Instrument calibration, though unavoidable, is
extensively time and resource consuming.
• Now most of the available digital instruments are
provided with communication interfaces, hence
remote calibration from the actual hardware and
computing unit with Internet connection capabilities
is possible.
• Remote calibration is very important and useful to
Regulators to know that the analyser is generating
correct data and that there is no tampering to the
instrument.

Conclusion
 Whatsoever way the data may be gathered and
analyzed, the data itself reflects processes that are
occurring in the real world.
 Factors such as pesticide in drinking water or
changes in ambient air quality may be represented
by numbers or charts, but in reality they represent
impacts on individual organisms, on human and
biological communities, and on entire ecosystems.
 Scientists, policy makers and the public should do
well to realize that decisions based on data, however
arcane, ultimately translate back to the real world as
actions and outcomes.
