COMENIUS PROJECT

ISIS MALIGNANI 2000 CERVIGNANO DEL FRIULI


Comenius project

WE HAVE MEASURED:

  • AOT;

  • Relative Humidity (%);

  • Temperature (°C);

  • Pressure (mbar);


Comenius project

Where?

In Cervignano del Friuli at

Latitude 45°49'4"08 N

Longitude 13°20'41"28 E

Decimal degrees 45,8178; 13,3448

The red circles indicate the areas that influence the AOT


Comenius project

When?

We have just continued the measurements made by the previous 4th class. Infact the measurments started in September 2011, we have replaced our school mates since September 2012.


Comenius project

Data assessment

We compared AOT data with:

  • Temperature (°C);

  • Pressure (mbar);

  • Relative Humidity (%);

The results are shown in the following graphs..

AOT

Days are numbered from 1 (1st of October) to 61 (30th of November)

New comparisons

This time we also tried to compare AOT with wind speedand satellite data. We tried to take measurements at same time of satellite overpassing (Aqua)

Wind speed: from www.eurometeo.com

Satellite data: from Nasa:Giovanni - Interactive Visualization and Analysis

It should be noticed that Satellite measures AOT at 550 nm while we measure it at 505 nm.

CONCLUSIONS

AOT-P: no clear relation.

AOT-T: no clear relation.

AOT-% H: graphs evidence the same behaviour

(infact aerosols are also made of liquid droplets)

AOT-wind speed: high wind speed results in low AOT and viceversa

ANOMALIES: very high values of AOT have been measured on 18th and 19th october. A possible reason is a fire in Venice province, at a distance of about 100 Km from our site.
