Project Title:Urban Trees Role in City Park

Project Description: An Assessment of the Role Urban Trees Play in Modifying Weather in a City Park
Abstract: 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.
Protocols:Air Temperature, Barometric Pressure, Relative Humidity, Surface Temperature, Wind, Biometry (including Tree Height)

From Dr. Dixon Butler (https://www.globe.gov/web/dixon.butler): This project is improved from the version submitted to the IVSS. You certainly did much work on this project. The differences in wind speed do not appear to be related to the presence of trees as the wind speeds are not consistently greater in either location. If you were to repeat this investigation what improvements in site characteristics would you seek?

Very interesting project.  It looks like the trees in this park are pretty limited, and that the foliage is not all the way to the ground.  It would be interesting to try this project in a place that has more trees, or more substantial vegetation cover. There must be some limited amount of vegetation required before you will see much impact.
 I also think summer - when shade really matters - would be an interesting season to study.
Nice poster!

Zaher, Mohamedhussin, and Anas -

I'm Shan Zuidema, a Research Scientist and PhD candidate at the University of New Hampshire.  I use computer simulation models to see how humans and watersheds interact - how we rely on water resources and how we can alter and contaminate water bodies such as aquifers and rivers.

Thank you sharing your work on the microclimate effects of trees in an urban park.  I liked how you are chosing a clear hypothesis, and making a straightforward clear paired study.  Your graphs really clear illustrate your findings.  Since you measured meteorologic variables in the winter and spring, do you think you captured the full effect of trees on micro-climate in your study area? You mention you'd like to extend the study to different times of the year.  Can you hypothesize how the presence of leaves might affect some or all of the meteorologic variables you measured?  This could be a good thing to put in a discussion to mak the reader more excited for future research.  What types of trees were in the park?  I noticed you mentioned measurements of tree height and DBH.  It would be good to tie those measurements into the hypothesis that you are testing.
