Protocol eTraining Modules

Learn how to take canopy cover and ground cover measurements at your GLOBE land cover sample site. This module provides a step-by-step introduction for how to measure canopy cover using a densiometer, measure ground cover and prepare the data for upload to GLOBE.

Learn how to determine the graminoid (grass-like plant) biomass at your GLOBE land cover sample site. This module provides a step-by-step introduction of the protocol method. After completing this module, you will know how to conduct sampling procedures in the field and complete measurement procedures in the lab, and you will be able to upload your data to GLOBE.

In identifying the land cover of your sample site, you may need to measure the height of the vegetation at your site. This module will help you learn to  measure the average height of the vegetation. For low-lying vegetation, such as grasses, and medium height vegetation, such as shrubs,  you will take a random sample of plants, measure them, and calculate the average plant height. 

Learn how to measure a tree circumference at your GLOBE land cover sample site.  You take your tree circumference measurements on the same 5 trees you selected for tree height using a flexible tape measure at 1.35 meters above ground level.

Set up a non-standard carbon cycle site to take carbon and plant growth measurements using the GLOBE Carbon Cycle protocols. Determine which vegetation types you will measure, perform field measurements to assess carbon storage and plant growth, and upload data to the GLOBE database.

Learn how to set up a STANDARD Carbon Cycle Site to take carbon and plant growth measurements using the GLOBE Carbon Cycle Protocols. A Standard site is an area of at least 225m2 (15x15m) of contiguous vegetation (i.e. forest, grassland, shrubland), if your site has human interference (i.e. school yard, park, etc.) please complete the NON-STANDARD Protocol eTraining. This module reviews learning activities and research questions that you can you can address using the Carbon Cycle protocols, the selection of a Standard GLOBE Carbon Cycle site, and provides a step-by-step introduction of the Standard Tree, Shrub/Sapling, and Herbaceous protocols. After completing this module, you will be able to determine which vegetation types you will measure, perform field measurements to assess carbon storage and plant growth, upload data to the GLOBE database, and understand resources available to help you analyze and interpret your data.

As part of phenology we study the seasonal and climatic changes in the environment. In this module you will learn about the green-down phase for grasses. Green-down marks the end of the growing season and the beginning of dormancy for the grasses.

As part of phenology we study the seasonal and climatic changes in the environment. In this module you will learn about the green-up phase for grasses. Plant green-up begins as the dormancy of the grass is broken by changes in environmental conditions such as more hours of daylight and an increase in air temperatures.

As part of phenology we study the seasonal and climatic changes in the environment. In this module you will learn about the green-down phase for trees and shrubs. Green-down begins as the hours of daylight begin to lower and temperatures begin to lower.

Phenology is the study of the effect of seasonal and climatic changes in the environment. In this module you will learn about the green-up phase for trees and shrubs. Plant green-up is often seen as the buds of the trees and shrubs open caused by changes in environmental conditions such as more hours of daylight and an increase in air temperatures.
