Michelle Gierach

Education
  • B.S., Meteorology, Florida State University, Tallahassee, Florida (2004)
  • M.S., Meteorology, Florida State University, Tallahassee, Florida (2006)
  • Ph.D., Marine Science, University of South Carolina, Columbia, South Carolina (2009)

Research Interests

Application of satellite and airborne observations, in-situ data, and model simulations to study synoptic to decadal changes in the ocean, with specific focus on biophysical interactions, coastal water quality, and carbon fluxes.


Projects

CMS Flux (Carbon Monitoring System Flux) Icon CMS Flux (Carbon Monitoring System Flux)
Carbon Monitoring System Flux (CMS Flux) incorporates the full suite of NASA observational, modeling, and assimilation capabilities to attribute CO2 climate forcing to spatially resolved emissions.

CORAL (COral Reef Airborne Laboratory) Icon CORAL (COral Reef Airborne Laboratory)
CORAL will provide the most extensive picture to date of the condition of a large portion of the world’s coral reefs from a uniform data set.

OCO-2 - Orbiting Carbon Observatory Icon OCO-2 - Orbiting Carbon Observatory
The Orbiting Carbon Observatory-2 (OCO-2) is a mission designed to make precise, time-dependent global measurements of atmospheric carbon dioxide (CO2) from an Earth orbiting satellite.

ORCAS (O<sub>2</sub>/N<sub>2</sub> Ratio and CO<sub>2</sub> Airborne Southern Ocean) Icon ORCAS (O2/N2 Ratio and CO2 Airborne Southern Ocean)
The O2/N2 Ratio and CO2 Airborne Southern Ocean (ORCAS) Study is an NSF sponsored airborne field campaign with research flights planned from Punta Arenas, Chile during January and February of 2016.

PRISM (Portable Remote Imaging SpectroMeter) Icon PRISM (Portable Remote Imaging SpectroMeter)
Portable Remote Imaging SpectroMeter (PRISM) is a compact lightweight, airborne instrument compatible with a wide range of aerial vehicles.
