COMENIUS PROJECT

This project conducted aerosol optical thickness measurements in Cervignano del Friuli, focusing on AOT data comparison with temperature, pressure, humidity, and wind speed and satellite data analysis. Results, conclusions, and anomalies were documented.

  1. COMENIUS PROJECT ISIS MALIGNANI 2000 CERVIGNANO DEL FRIULI

  2. WE HAVE MEASURED: • AOT; • Relative Humidity (%); • Temperature (°C); • Pressure (mbar);

  3. Where? In Cervignano del Friuli at Latitude 45°49'4"08 N Longitude 13°20'41"28 E Decimaldegrees 45,8178; 13,3448 The red circles indicate the areas that influence the AOT

  4. 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.

  5. Data assessment We compared AOT data with: • Temperature (°C); • Pressure (mbar); • Relative Humidity (%); The results are shown in the following graphs..

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

  7. AOT and Pressure

  8. AOT and Temperature

  9. AOT and Humidity

  10. 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.

  11. AOT and Wind speed

  12. Satellite measurements

  13. Sunfotometer AOT and satellite AOT

  14. CONCLUSIONS AOT-P: no clear relation. AOT-T: no clear relation. AOT-% H: graphsevidence the samebehaviour (infactaerosols are alsomadeofliquiddroplets) AOT-windspeed: high windspeedresults in low AOT and viceversa ANOMALIES: very high valuesof AOT havebeenmeasured on 18th and 19th october. A possiblereasonis a fire in Venice province, at a distanceofabout 100 Km fromour site.
