Abstract

During 2 - 19 June 1991 the Atmospheric Turbulence and Diffusion Division of NOAA measured flux densities of mass, momentum, and energy from an airplane in support of DOE's Atmospheric Radiation Measurement (ARM) program. Over 507 horizontal flux transects were completed, along with 24 vertical atmospheric profiles, during the 93 flight hours. Flux transects passed over both irrigated farmland and steppe. The report describes the variation in wind, radiation, and surface temperature, along with exchange of mass (CO2, H2O, and O3), momentum, and energy as observed along the transects. Airborne measurements are compared with those from flux towers in wheat, corn, and steppe. In general, the measurements correspond well. The largest difference occurs at the steppe tower, with stronger heat fluxes reported by the tower. This discrepancy increases as heat flux increases. The cause may be a significant vertical flux divergence or an inconsistant specification of the mean state.

Areally averaged estimates of surface heat flux from ARM field studies

Conference Coulter, R; Martin, T; Cook, D

The determination of areally averaged surface fluxes is a problem of fundamental interest to the Atmospheric Radiation Measurement (ARM) program. The Cloud And Radiation Testbed (CART) sites central to the ARM program will provide high-quality data for input to and verification of General Circulation Models (GCMs). The extension of several point measurements of surface fluxes within the heterogeneous CART sites to an accurate representation of the areally averaged surface fluxes is not straightforward. Two field studies designed to investigate these problems, implemented by ARM science team members, took place near Boardman, Oregon, during June of 1991 and 1992. The sitemore »« less

The boardman regional flux experiment

Journal Article Doran, J; Hubbe, J; Kirkham, R; ... - Bulletin of the American Meteorological Society; (United States)

A field campaign was carried out near Boardman, Oregon, to study the effects of subgrid-scale variability of sensible- and latent-heat fluxes on surface boundary-layer properties. The experiment involved three U.S. Department of Energy laboratories, one National Oceanic and Atmospheric Administration laboratory, and several universities. The experiment was conducted in a region of severe contrasts in adjacent surface types that accentuated the response of the atmosphere to variable surface forcing. Large values of sensible-heat flux and low values of latent-heat flux characterized a sagebrush steppe area; significantly smaller sensible-heat fluxes and much larger latent-heat fluxes were associated with extensive tracts ofmore »« less

An experimental and numerical study of boundary layer structure over areas of inhomogeneous sensible heat fluxes

Conference Zhong, S; Doran, J

In June of 1992 a boundary-layer experiment was carried out near Boardman, Oregon. The campaigns were part of a program of studies under the auspices of the US Department of Energy`s Atmospheric Radiation Measurement (ARM) program, whose goal is to improve the treatment of radiative transfer, particularly as affected by clouds, in general circulation models (GCMs) used for climate studies. One aspect of this program is concerned with the determination of appropriate lower boundary conditions for such models and the representation of subgrid-scale variability in regions where the surface conditions are not uniform. To study this problem, boundary-layer and surfacemore »« less

Measurement and analysis of the surface energy budget for ARM field experiments. Final report

Technical Report Kunkel, K

The objective of this study is to conduct experiments to investigate the scaling properties of surface-atmosphere interactions and feedbacks as they relate to regional fluxes of heat and water vapor. This is part of the US Department of Energy`s Atmospheric Radiation Measurement program. To achieve this objective, two field campaigns were conducted in northeastern Oregon during June 1991 and June 1992. Analysis of the data collected during these campaigns revealed the following: (1) fluxes over a dry, semi-arid grass/brush area show only small spatial heterogeneity; (2) fluxes over an irrigated farm were dependent on crop type and stage of development.more »« less

Spatial and temporal variability of heat, water vapor, carbon dioxide, and momentum air-sea exchange in a coastal environment

Journal Article Crawford, T; McMillen, R; Meyers, T; ... - Journal of Geophysical Research

The spatial and temporal variability of heat, moisture, momentum, and CO{sub 2} turbulent fluxes in a coastal environment were assessed using simultaneous eddy correlation measurements from a tower, a boat, and an aircraft platform. The flux measurements were made using new instrument systems, including new CO{sub 2} and H{sub 2}O sensors, low-flow distortion packages, and careful sensor motion correction systems. The flux tower was operated on the windward beach of Florida`s Bahia Honda Key, while the boat was stationed upwind between 1 and 15 km offshore. The airplane flew transects 10 to 20 m above the ocean surface, along flightmore »« less
