Using computational fluid dynamics and field experiments to improve vehicle-based wind measurements for environmental monitoring [PDF]

open access: yesAtmospheric Measurement Techniques, 2020
Vehicle-based measurements of wind speed and direction are presently used for a range of applications, including gas plume detection. Many applications use mobile wind measurements without knowledge of the limitations and accuracy of the mobile ...

Explaining CO2 fluctuations observed in snowpacks [PDF]

open access: yesBiogeosciences, 2018
Winter soil carbon dioxide (CO2) respiration is a significant and understudied component of the global carbon (C) cycle. Winter soil CO2 fluxes can be surprisingly variable, owing to physical factors such as snowpack properties and wind.

Risks and Risks [PDF]

open access: yesScience, 2005
When society makes a decision about some action (to build a dam or approve a new drug, for example), its choice is usually based on a comparison of risks and benefits. If the latter exceed the former, assuming that risks and benefits accrue to the same person or group, the project goes forward ...
