A Comparison of Daily Air Temperature and Number of
Observed Contrails

Queens, NY

The intent of this research project was to compare
the local daily air temperature, as recorded from
Weather.com, to the number of contrails observed by
a set of students at Lexington School for the Deaf.
The hypothesis that more contrails would be
observed when the temperature was lower (colder)
was not supported by the data collected during this

Research Question

At what type of temperature in the atmosphere
do more contrails form?

Our hypothesis is that we think that when the
weather is colder we will see more contrails.

Research Methods
Experimental Plan
1. My classmates collected the Globe Contrail Chart and
Cloud Identification Chart.
2. We went outside in the school field, then we observed
the sky to find any visible clouds and contrails.
3. We recorded data information about what type of
clouds, cloud cover percentage, sky color, and
contrails we saw.
4. We checked Weather.com for the temperature and air
5. We went to Google Drive; we recorded data
information about clouds, cloud cover percentage,
sky color, and contrails in GLOBE Google Sheet.
6. We used data from 31 days of observations to make a
graph representing the trend between temperature
and contrails.

Study Site

Lexington School for the Deaf is located in Queens,
New York.
This is an urban area that is a borough of New York
The school is located in an area that is characterized
by typical climate patterns following the four seasons
of the northeastern region of the United States of
There are a few trees and buildings that block the view
of a small portion of the sky for daily observations
while on the school grounds. However, more area of
the sky is visible than would typically be possible at an
urban school location.
Lexington School for the Deaf is located approximately
2 miles from LaGuardia Airport.
Observations were collected in accordance with
GLOBEs Cloud Protocols, including the use of: GLOBE
SCool Cloud Identification Chart, GLOBE
Chart, GLOBE Field Guides, and the GLOBE Observer
app; to record information about airplanes in the area,
the Flightradar24 app was used.
Data were organized into a class-wide GoogleSheet.
Data were collected as often as possible (weather
permitting) during weekdays that school was in
session. On Mondays and Fridays, data were collected
between 9:30am-11am EST and Tuesday-Thursday
data were collected between 1pm-2pm.

We went outside to record cloud observations and look
for contrails. We observed the sky and observed
contrails then we recorded data on the GLOBE chart.
Also, we used the Calitoo sun photometer to find the
aerosol optical thickness of the atmosphere and
recorded data.
We started our observations in November 2018 to April
2019. Our goal was to find what type of air
temperature we would see more contrails.

Figure #5: Graph Analysis

Our hypothesis states that more contrails will form
during cold weather but our results do not support this
theory. Our data show that more contrails may form at
higher temperatures. We expect to see more contrails
with increase of temperature because of positive
correlation on graph.

Error Analysis and Future Steps

Our data collection only took place during the winter
and spring. That is one reason there is not enough
data information to support our research project and
draw detailed conclusions.
Students did not have WiFi connected to their phone
to use during outdoor sky observations during the 4
months of data collection because school does not
allow students
to connectCollaborations,
WiFi.. We could improve by
having access to WiFi which would allow all students
use the
GLOBE Observer app and Flightradar24
app. This would allow for more uniform data

This research was completed with the help and support of a number of outside
participants. This project would not have been possible without our collaborators. We
would like to give special thanks to NASAs Langley Research Center, including but not
limited to Rosalba Giarratano, Maril Coln Robles, Dr. Margaret Pippin, William
Wood, Christina York, Tina Harte, and Jessica Taylor. We had the great privilege of
having a video conference via Zoom with this amazing group of scientists in the spring
of 2018 regarding our research and future interests and they have continued to
provide support and encouragement.
We would also like to thank our family at the Lexington School for the Deaf for their
continued support and interest in our endeavors. Special thanks to our administrators
and staff who have continued to encourage our projects and goals, including but not
limited to Don Galloway, Jane Moran, Frank Dattolo, Cindy Casson, Amanda
Heinbaugh, Dolly Dominguez, and Bill Moran.

Data Analysis

We saw a trend that suggests a positive correlation
between temperature and number of contrails
observed. However, it is not a strong relationship,
based on the R2 linear regression value.


Last but not least, we would like to thank Jennifer Bourgeault and Haley Wicklein of the
GLOBE Program for helping us obtain funding and make travel arrangements for our
Cloud Protocols;

to be possible!
