The seasonal variation of ozone in the troposphere and lower stratosphere above … Global Atmosphere Watch stations Macquarie Island (in the subantarctic) and Davis … (in Antarctica) is examined using three years of ozonesonde measurements.
Fresnel transform meteor speed estimation is … investigated. A spectral based technique is developed allowing the transform to be applied at low temporal sampling rates. Simulations are used to compare meteoroid … speeds determined using the Fresnel transform and alternative techniques…
Many contaminated cold region soils are deficient in nitrogen, and addition of the proper amount of this nutrient can increase the biodegradation rate. However…
We use line transect detection functions together with generalized linear and additive … models to estimate detection probability when detection on the line ("g(O)") may … not be certain.
