Today we will get a closer at look at the values displayed on our Calitoo screen.
When you first turn on your Calitoo, you will get a screen like the following: note the serial number of your instrument will be displayed.
After the initial screen, your instrument will display basic information as shown on the following picture (Source: http://www.calitoo.fr/uploads/documents/en/usermanual_2016_en.pdf)
TIP: The temperature displayed by your Calitoo is actually the temperature inside the instrument.
Today we start a series of posts devoted to providing information, tips, tricks and answers to frequently asked questions by Calitoo users!
So, how do you measure Aerosol Optical Thickness (AOT) with a Calitoo?
First and foremost: NEVER look directly at the sun!
And…ONLY take measurements when the sun is not obstructed by clouds.
TIP: Use your hand(s) to cover the sun; if you see any clouds on either side of your hand(s), do NOT take any measurements. Wait until the sun is not obstructed by clouds.
Now, the Calitoo sun photometer measures AOT values at 465 nm, 540 nm and 619 nm. ...
A fourth grade student from Public School 122 (Queens, NY), recently visited NASA Langley for a week. During his visit, he studied the GLOBE Aerosol Protocol. He went outside the Atmospheric Sciences building and collected aerosol data using a Calitoo sun photometer, which measures Aerosol Optical Thickness (AOT) at three wavelengths: 465nm (blue), 540nm (green) and 619nm (red).
After downloading the data measured with the Calitoo to his laptop, the student learned how to access AERONET data. The AERONET (AErosol RObotic NETwork) project is a federation of ground-based remote sensing...
The NASA GLOBE Clouds team recently presented a webinar the details of how your cloud observations are matched to satellite data. The webinar, recording found below, also focuses on the importance and quality of the observations, ways that the data can be used by scientists, and current work being done by the team at NASA Langley Research Center in Hampton, VA. The webinar also highlights newly processed data from the temperature and cloud observations reported for the Great North American Solar Eclipse on August 21, 2017.
See how your data is collected...
This past week was a very exciting one for the Science Education Team at NASA Langley Research Center! Four members visited one of the schools participating in the GLOBE Air Quality Student Research Campaign: Our Lady of Mount Carmel School, in Newport News, VA., where twenty middle school students, led by their science teacher Ms. Angie Rizzi, presented their team research projects and posters about aerosols.
After students started taking aerosol measurements and once they had selected their research project questions, Dr. Pippin, -lead scientist for the GLOBE Air Quality Student Research...
