Transcript of Earth, Atmospheric and Planetary Physics · Planetary Physics Getting to know us weekend ......
● We apply Math, Physics, and computing to study complicated systems related to the Earth, and other planets
○ Strong link between fundamental research in Physics (Fluid Dynamics, Spectroscopy, numerical methods, etc.) with practical applications
● Many Real World Applications:○ Stratospheric Ozone Loss○ Present and Future Climate Change○ Mantle Convection○ Exoplanet Identification
What we do
Why study in EAPP? ● Lots of fantastic faculty and students ● Fantastic Research Infrastructure available
○ Eureka Lab○ Spectroscopy Lab○ Atmospheric Observatory○ Advanced Research Computing: Scinet ○ Seismology Lab
● Strong community with many seminars/activities○ Brewer Wilson Student Seminars○ Atmospheric Physics Seminars○ Noble Lectures○ J. Tuzo WIlson Lectures ○ Centre for Global Change Studies Seminars
● Many Career Paths possible (research, industry, professional)
Can I study in EAPP?● Yes!
○ The most important thing is that you have a strong background in math and physics
○ If you’re sitting here then you have the background to join the group!● Typically students take courses in a wide array of areas
○ Fundamental Physics○ Data Analysis ○ Subject Specific Courses
● Many professors have multiple active research projects and are seeking students
○ Talk to them!○ Many things are possible!
Atmosphere/Ocean/Climate Dynamics
● Geophysical Fluid Dynamics:○ Fundamental Turbulence Modelling○ Internal Waves○ Simplified Modelling ○ Field Measurements
● Climate Modelling ○ Ice Age simulations○ Climate Change simulations○ Sea Ice○ Hydrological Cycle
● Experimental:○ Space-based remote sensing○ Instrument and mission development○ Calibration and validation of satellite
instruments ○ Field campaigns, observatories, and
networks, laboratory● Data assimilation, inverse modeling:
○ Exploitation of satellite data sets○ Chemical data assimilation○ Inverse modeling of carbon fluxes
Atmospheric Composition
Planetary and Geophysics● Geophysics
○ Pattern Formation○ Inverse Modelling ○ Mantle Convection
● Planetary Physics○ Structure and Composition of
Exoplanets ○ Planetary Development ○ Planetary Atmospheres
Experimental: Constrain city emissions
Want to know concentration of a gas
Measured spectra
Remote sensing
y=f (x)
Experiment
Results
Monitor emissions of greenhouse gases from Toronto
We have made measurements of CO2, CH4, CO, and N2O for 4 months.
We found that CH4 (methane) has strong wind direction dependence, suggesting a nearby source. Possibly a natural gas leak?
Numerical: Constrain global CO2 fluxes
FLUX
Want to know flux
Measure atmospheric CO2
Data assimilation
y=f (x)
Observations will be assimilated
FLUX
Want to know flux
y=f (x)
--Experiment
Assimilate atmospheric CO2 observations to improve biosphere flux estimates
Data assimilation
Results● We estimate anomalies in fluxes
of CO2 from the terrestrial biosphere in the summer of 2013.
● We find that there is an anomalous flux of CO2 to the atmosphere in California, over the same period as a drought conditions and a warm summer
Numerical: Constrain global CO2 fluxes
Measure atmospheric CO2
