ISIS MALIGNANI 2000 CERVIGNANO DEL FRIULI
WE HAVE MEASURED:
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
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.
We compared AOT data with:
The results are shown in the following graphs..
Days are numbered from 1 (1st of October) to 61 (30th of November)
AOT and Pressure
AOT and Temperature
AOT and Humidity
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.
AOT and Wind speed
Sun fotometer AOT and satellite AOT
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.
