MESURER LE MICROCLIMAT

THE INSTRUMENT
PACK OF THE FUTURE

CURRENTLY INSTRUMENTS which
collect high quality microclimate data
are large, delicate and expensive.
A typical set of instruments costs
$20,000 and requires an expert to
operate. We want to produce an
instrument pack that is smaller than a
deck of cards, costs less than $100, and
will transmit measurements of current
conditions to mobile devices that
anyone can use.
As far back as the 1980s, when I
was still an MLA student, Dr. Terry
Gillespie and I invented a simple
but powerful instrument called a
Cylindrical Radiation Thermometer
(CRT) to measure amounts of solar
and terrestrial radiation that a
person receives. It's a cylinder with a
thermometer in it which, combined
with measurements of wind and air
temperature and some complex
mathematics, yields surprisingly
accurate measurements. The
new electronic version, shown in
Photo 1, is used widely in the academic
community and hopefully will soon be
used in the professional community
as well.
A miniature anemometer, shown in
Photo 2 in magnified image, measures
the wind speed. Dr. Tim Logan has
developed a tiny instrument, shown
in Photo 3, that senses aerosols, and
thus can measure air pollution levels. In
Photo 4, we are making our own parts
using a 3-D printer.
This tiny package will be easily
deployed in a landscape (or mounted
on a bicycle, or carried by a person)
to measure all the key aspects of
microclimate that affect a person's
thermal comfort. Photo 5 shows the
"ClimaCycle" fitted with instruments
to measure temperature, humidity,

wind speed and direction, terrestrial
radiation, solar radiation and albedo
rates. Data is stored in a datalogger
and the bike is equipped with a
GPS-equipped tablet to guide the
rider, Ph.D. student Wenwen Cheng,
to pre-planned waypoints for data
capture. A 3DR drone outfitted with
a FlirDuo camera, shown in Photo 6,
simultaneously captures video and still
images of side-by-side thermal infrared
and visible light imagery. We're hoping
to build and deploy several prototypes

...an
instrument
pack that
is smaller
than a deck
of cards...

in 2018, with the idea of helping
disadvantaged neighbourhoods in
Houston be safer during heat waves,
and more thermally comfortable
throughout the year. We're optimistic
that we are making good progress
- even taming the invisible forces at
work in the landscape - to create safe
and thermally comfortable urban
environments even in an uncertain
future climate.
