Watching the planet breathe: Studying Earth’s carbon cycle from space

Average carbon dioxide concentrations, Oct. 1 – Nov. 11, 2014, measured by the Orbiting Carbon Observatory-2 satellite. NASA Berrien Moore III, University of Oklahoma and Sean Crowell, University of Oklahoma Carbon is a building block of life on our planet. It is stored in reservoirs on Earth – in rocks, plants and soil – in … More Watching the planet breathe: Studying Earth’s carbon cycle from space

Numerical Integration and the Fundamental Theorem of Calculus

I occasionally get to think about fun math problems while I’m doing work in applied science. The most recent example of this came up in a conference call. We are concerned about how a satellite measurement will respond to surface pressure changes. Theoretically, the measurement is an integral of the amount of a trace gas … More Numerical Integration and the Fundamental Theorem of Calculus

Craig Bishop: The Secrets of Model/Background Error Covariance Revealed

This is my first content post for the satellite data assimilation summer school, and the first big insights that I’ve gotten by being here. These come courtesy of Dr. Craig Bishop of the Naval Research Lab in Monterrey, California. In my previous post, I talked about the difficulty I had of envisioning model error as … More Craig Bishop: The Secrets of Model/Background Error Covariance Revealed
