Data can also be
displayed as contours
in a map.
This map displays the mean air temperature
in Europe on
May 23, 2003.
Data from up to six schools can be displayed in the same graph.
This is the maximum air temperature for schools in Australia, Benin and Finland.
Air temperature and
can be seen for Northern
and Southern hemispheres
as well as Equatorial.
GLOBE Students can
compare their data with data from satellite and

Students use GLOBE measurements to ask questions about their local environment.
This school in Benin graphed cases of malaria in the community with temperature and precipitation.

Measurements based on
instruments can be used
to evaluate satellite-based
methods of estimating aerosol

Strange streak of MODIS-identified snow in Ohio that GLOBE observations showed was not snow.
2. Validating ecosystem models (GAPS)
1. Comparing soil profile properties at different locations
100 cmSoil Characterization and Modeling using GLOBE Student Observations
Objective: To determine the effects of corn and soybean
tillage on the atmosphere, streams, soils, and phenology
CHALLENGE: measure effect of land cover
Response: T and RH at 1.5 m above “effective surface”
Design weather-station mount that enables
moving instruments upward as crops grow
CHALLENGE: How to interpret differences between
Response: Calculate expected T and RH profiles for
different stages of crop growth, expected

Part of Soil Moisture Experiment 2003 (SMEX03)
1. Part of gravimetric soil moisture data set
(measurements at 0-5 cm; 8-12 cm)
2. In-situ soil moisture compared to values
from aircraft and spaceborne instruments
3. Teachers and students know measurements
relevant to science
Washburne is also doing this for NAME
(North American Monsoon Experiment)
Some examples proposed by GLOBE PIs and others
Aerosol observations after
Rainfall measurements before
and during a hurricane
(or the remnants) – this
is not always practical!
Compare instruments or different
(Sister Shirley experiment)
BUT: it is important to report back
to the observers!
