Short-Period Gravity Waves Over Alaska, Michael Negale
Short-Period Gravity Waves Over Alaska, Michael Negale
Michael Negale
The propagation nature and sources of short-period gravity waves have been studied extensively at low and mid-latitudes, while their extent and nature at the polar regions are less known. During the last decade, observations from select sites on the Antarctic continent have revealed a significant presence of these waves over the southern Polar Region as well as shown unexpected dynamical behavior. In contrast, observations over the Arctic region are few and the dynamical behavior is unknown. A recent project was initiated in January 2011 to investigate the presence and dynamics of these waves over interior Alaska. This site provides an …

In Situ Checks Of Sonic Anemometer Temperature Calibration, David Cook, Michael Negale
In Situ Checks Of Sonic Anemometer Temperature Calibration, David Cook, Michael Negale
Michael Negale
The temperature calibration of the Gill Instruments WindMasterPro sonic anemometer used in the SGP ACRF ECOR systems is a curve, but is approximated as a linear fit for field use. The linear fit is only applied to the calculation of sensible heat flux and not to the reported temperature, and results in an underestimate of sensible heat flux during cold ambient temperatures and an overestimate during hot ambient temperatures. In situ calibrations performed using five years of ARM SGP ACRF data reveal how poorly the temperature is measured by the ECOR using the linear fit. Linear and non-linear in situ …

Sonic Anemometer Calibrations, Michael Negale, David Cook
Michael Negale
Initial conditions and boundary conditions are important for climate and atmospheric modeling. In order to get correct initial and boundary conditions, correct measurements need to be made. The eddy correlation flux measurement system (ECOR) is one such system that measures fluxes in momentum, sensible heat, latent heat, and carbon dioxide (CO2). These fluxes are calculated using the eddy covariance technique, which involves wind components, air temperature, water vapor, and CO2 concentration. The ECOR uses a fast response three-dimensional wind sensor, sonic anemometer (SA), to measure wind components and speed of sound, which is used to derive the air temperature. The …
