How to Participate in Cloud Measurements

How to Participate


Your observations are very important for scientists studying how cloud cover affects our climate. When you submit frequent measurements over time, your data provides NASA with greater detail on how our climate is changing. To start recording cloud measurements and submitting them to GLOBE, please follow the process below:


Step 1

Whether you're a citizen scientist, educator, student, or STEM professional, GLOBE welcomes you to take part in our dynamic Earth science research missions and educational campaigns. To create an account, check out our "Get Started Overview"


Step 2

When you coordinate your cloud measurements with a NASA satellite passing overhead (+/- 15 minutes), you provide particularly valuable data to atmospheric scientists. You'll also receive a follow-up email from NASA with satellite data so that you can compare your results from measurements taken on the ground with those taken from space.

To find out more about when satellites will pass over your location in the next two weeks, see the following resources:


Step 3

For GLOBE Teachers or GLOBE Students:

  1. Download the Protocol Data Sheet
  2. Submit your observations with either:

For citizen scientists:

  • Record and report your cloud observations using the GLOBE Observer mobile app.
    • Tip: Measurement reporting on the GLOBE Observer app is also available to GLOBE Teachers and Students.


Step 4

If you coordinate your cloud observations with an orbiting satellite, NASA will send you a Satellite Match email within 1 week of your data submission. This email will help you better understand cloud reporting and how NASA uses your measurements to calibrate their satellite's instrumentation.

Step 5

Browse our collection of all processed ground observations dating back to 1995.

Start exploring the NASA GLOBE Cloud Protocol archive.

If you're a GLOBE member, you can also explore NASA GLOBE Cloud data through maps, graphs, charts, and downloadable files for spreadsheet software via the following resources:
