FAQ: GLOBE Data
GLOBE Data Use
GLOBE Citizen Scientists also contribute to GLOBE's database by submitting their protocol measurements through The GLOBE Program's app, GLOBE Observer.
While the GLOBE correction improves site elevations overall, individual sites may still look incorrect. For example, schools near sea level may end up with a corrected elevation beneath sea level.
If you need more refined height estimates, you can get elevations from independent data sources. Just be sure the latitude and longitude are reported accurately and with precise degrees (four or five decimal positions).

GLOBE schools span many different time zones. They report their times in UT so that measurements from across the world can be compared with each other.
In order to convert your local time to UT, visit the Greenwich Meantime website, look up your local time and find the difference between UT and your local time. Add, if you are behind UT, (or subtract, if you are ahead of UT), this difference to any of your local measurement times to get the measurement times in UT.

Solar noon is the time of day when the sun appears to have reached its highest point in the sky. It is not usually the same time as “clock noon.”
Solar noon always occurs half-way between local sunrise and sunset. The average of the sunrise and sunset times is your local solar noon.
You can also check your local solar noon online.
