To assess the role trees play in modifying microclimates, an investigation was developed
to measure the size (height and DBH) of over 120 trees at a park in Dearborn, Michigan.
With the help of a professional forester, trees were identified by names for future research.
The GLOBE Observer App helped to collect and submit the data. In addition, two PASCO
weather stations helped to determine how trees modified selective weather parameters like
wind speed, temperature, and relative humidity of two different sites in Levagood Park.
Site 1 was an area centered among a group of trees, while Site 2 was in an open short grass
field without surrounding trees. Students would go to the sites, place their devices, and
begin recording simultaneously for approximately 15 minutes. The data was then used to
make graphs for comparing the two data sets. After analyzing the data, multiple
correlations were found between them. We found several similarities and differences
between the two sites. Although the data was collected during the winter with no leaves on
trees, we hope to continue our research during the active growing season of 2020 to
compare the effects with leaves to the data collected in the winter.
