We are excited to have such a response to the NASA GLOBE Clouds: Spring Cloud Observations Data Challenge .  Remember, top observers will be congratulated by a NASA scientist! Click here to learn more about the challenge.  Are you wondering about the clouds you are reporting and the type of weather you might experience in your area? Here is a guide to how cloud types are related to weather!  The information below was taken from the NOAA's SciJinks webpage -

Las nubes, son diminutas gotas de agua líquida en suspensión, o heladas si se encuentran a suficiente altura. Estas pequeñas gotas se mantienen en el aire debido a su pequeño tamaño, que oscila entre 0,2 y 0,3 mm de diámetro.   Sólo caen en forma de precipitación cuando llegan a medir entre 1 y 5 milímetros. Su color blanco característico se debe a que la luz del  Sol  que incide en estas gotitas, las cuales reflejan los colores visibles que conforman la  luz , quedando así la mezcla de todos ellos, es decir, el blanco.

It’s almost spring, the time of year when the looming change in seasons could lead to some pretty fascinating cloud activity in the sky. NASA and  the GLOBE Program  are asking for your help by taking part in a citizen science cloud observation challenge. From March 15 through April 15, citizen scientists of all ages can make up to 10 cloud observations per day using the  GLOBE Observer app  or one of the other  data entry options  (for trained GLOBE members). Challenge participants with the most observations will be congratulated by a NASA scientist in a...

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...

Hello, GLOBE Universe, No need to be cloudy and confused with identifying clouds!  There are easy questions that you can ask yourself to help identify what beautiful clouds you are seeing floating high above you. I created a Cloud Identification Guide to step you and your students through identifying clouds.  Here's a quick summary of the main questions.  Inside the cloud guide, there are additional hints to help you tell the difference between similar looking clouds by using special clues. Is it raining? -- this is the first important question because...
