Emmetropia Approach Dynamics with Diurnal Dual-phase Cycling

open access: yesVision Research, 1996
Numerical experiments are performed on a first order exponential response function subjected to a diurnal square wave visual environment with variable duty cycle. The model is directly applicable to exponential drift of focal status. A two-state square wave is employed as the forcing function with high B for time H and low A for time L. Duty cycles of (

Dust Emissions on Mars From Phoenix Lidar Measurements in Relation to Local Meteorological Conditions

open access: yesGeophysical Research Letters
The diurnal cycle of dust aerosols on Mars is studied by analyzing lidar observations at the Phoenix landing site under cloud‐ and fog‐free conditions and in the absence of elevated, long‐range transported dust layers. There is a pronounced diurnal cycle

Diurnal Changes in Photosynthesis in Sugarcane Leaves: I. Carbon dioxide exchange rate, photosynthetic enzyme activities and metabolite levels relating to the C4 pathway and the Calvin cycle

open access: yesPlant Production Science, 2000
Diurnal changes in carbon dioxide exchange rate (CER), stomatal conductance (gs), photosynthetic enzyme activities and metabolite levels relating to the C4 pathway and the Calvin cycle in sugarcane (Saccharum sp. cv.

Atmospheric boundary layer measurements at the 280 m high Hamburg weather mast 1995-2011: mean annual and diurnal cycles

open access: yesMeteorologische Zeitschrift, 2012
In this paper, the 280 m high Hamburg weather mast and its instrumentation are introduced. Digital data recorded since 1995 are used to calculate the mean annual and diurnal cycles of the primary climate variables (pressure, temperature, humidity, wind ...
