MIMIC (Morphed, Integrated Microwave
Imagery at
CIMSS)
MIMIC is
a real-time product that morphs microwave imagery
of tropical cyclones (hurricanes) into a smooth animation so that
forecasters
and analysts can see trends that are not apparent in the original
imagery. More recently, I've applied a similar technique to microwave satellite-derived total precipitable water vapor in MIMIC-TPW. |
3D-AQS (3D-Air
Quality System)
and IDEA
I am project manager for CIMSS for the 3D-AQS project.
Our contribution at
CIMSS
is to design a three-dimensional visualization of satellite and lidar
retrievals of aerosol over the U.S. This builds naturally from our
previous
two-year project, IDEA
(Infusing Data into Environmental Applications),
which
is an experimental web-based service to provide daily,
national
imagery of aerosol derived from MODIS
for air quality forecasting.

Tropopause folding and
turbulence detection
I am currently doing research to detect clear-air turbulence
from tropopause folding and mountain-wave signatures in satellite water
vapor
imagery. This is part of the SNAAP program. |
Morphing satellite imagery
I have a general interest in adapting morphing algorithms to
satellite imagery – this has been very successful in the
MIMIC project,
but it is also helpful in modeling new satellite platforms, such as
with these
examples that I created for the GOES-R
Risk
Reduction project.

Previous endeavors
GOES
Layer
Average Specific Humidity (GLASH)
(aka The Specific Humity Product, Altered Water Vapor, T_6.7alt, ...)
My Master's
thesis was to design a derived product that 'corrects' the
GOES water vapor channel for temperature and zenith angle 'biases' in
order to view only the variation in brightness temperature due to
water vapor concentration.
Estimating
mass flux at the
tropopause from satellite
imagery
My Ph.D.
thesis related GOES water vapor gradients to
tropopause folding episodes in order to estimate how
stratosphere-troposphere
exchange could be measured by satellite. This was supported by the TOPSE
(Tropospheric Ozone Production about the Spring Equinox) project.
PROPHET:
Program for Research
on Oxidants:
Photochemistry, Emissions and Transport
As a graduate student I provided meteorological support for
this ongoing air chemistry experiment at the University of Michigan
Biological
Station by mentoring undergraduate students, operating the radar wind
profiler
and analyzing air parcel trajectories.

Hurricane
intensity chart in mph, kmph, kts and mps
Here are some of my matlab scripts that are in demand. Just a simple
acknowledgment is all I ask:
- griddataSwath.m
- Interpolation
of satellite swaths without edge artifacts
- pcolorCentered.m
- Display swaths of satellite data in checkered format without position
offsets
- areaReadTemp.m
- Read area files into Matlab structures
- combineImages.m - Creates data for a semitransparent overlay of a colored image on a grayscale image
- geoInterp.m - Cubic interpolate on a geographic track, accounting for a possible crossing of the antimeridian
- geostatParallaxCorrection.m - Creates a new navigation for geostationary images corrected for parallax
