   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. When you...

As spring begins here in the northern hemisphere, we often see seasonal changes in our precipitation patterns. As most of you know, heavy rains can result in the mass movement of land- known as "landslides".  These natural hazards occur all over the world, and often result in destruction of property and even death. Scientists at NASA's Goddard Space Flight Center are in the process of building an open worldwide database for landslide research- and we need you to help us out! Learn about the "Landslide Reporter" citizen science program in this blog.  Learn more about NASA's...

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. ...

The GLOBE Program is in a unique position to provide citizens worldwide with amazing benefits. One of the biggest benefits, I feel, it that of gaining a larger perspective. I work at Goddard Space Flight Center with the GPM (Global Precipitation Measurement) mission. This Earth-observing satellite is able to measure global precipitation and update these measurements every 30 minutes. You can see the latest data animation for the past week here. As NASA is a key sponsor of The GLOBE Program, many of us who work for NASA are able to share the unique perspectives that Earth-observing...

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...
