Event information

April 2019-Land Cover (Spring in the Northern Hemisphere, Fall in the Southern Hemisphere) Begins April 1, 2019!

Intensive Observation Periods (IOPs) are focused periods of time where participants are encouraged to collect large amounts of data and enter it in the GLOBE database. Data that is collected during an IOP will provide other GLOBE students, scientists, researchers, and educators large amounts of concentrated data over a short period of time. This can also be referred to as "Data Density." Ground-based data density can serve as way to help validate data coming from satellites and airborne instruments.

For instance, if GLOBE students take multiple measurements of tree height and land cover over a short amount of time and build up a strong database, scientists working with the ICESat-2 satellite tree height data can use the IOP student data to help validate the ICESt-2 tree height measurements. Scientists working with land cover data from the Landsat satellite can do the same for land cover.

During each IOP, GLOBE students will:

  • Take measurements of tree height (January and July) or land cover (April and October) and one additional protocol, from the suite of campaign protocols found at,  
  • take measurements at least three times per week for one month at the same study site for both protocols.
    • The tree height measurements should be of the same trees each time for each site.
    • You can have multiple sites, thus increasing the number of trees measured.
  • report their number of tree height measurements and identify the additional protocol measurement and number of measurements by the 5th day of the following month to Brian Campbell

Each participant will receive a Virtual Tree Height IOP Badge

The GLOBE school with the most collected tree height data and additional protocol data will receive: 

·        A Virtual one-on-one Q and A session with a NASA scientist, researcher, or engineer. 

·        Virtual Tree Height IOP Winner Badge

The major goal here is to have students compare their measurements seasonally and with other GLOBE school measurements from around the world.
