The site was established in summer 2014 and is part of the Oregon eddy covariance flux tower network . Meteorological variables such as temperature, humidity, solar irradiance and wind are measured at this site. Turbulent fluxes of water vapor, carbon dioxide and heat are observed and stored as 30 minute averages. The crop changes periodically and rye grass and fescue is grown alternately at this site located in Oregon's Willamette Valley with its relatively mild climate. The Wheat site is also part of the PhenoCam network operated by Harvard University and the University of New Hampshire. See MoreShow Less |

| 2024-12-04 | Zhang Haowei | AmeriFlux BASE | 1-5 | Other | The data will be used for analyzing and modeling ecosystem carbon and water fluxes, particularly focusing on soil moisture and its relationship with environmental factors such as temperature, precipitation, and vegetation types. The primary goal is to understand the dynamics of soil moisture across different ecosystems and its role in the carbon and water cycles. The data will also be used for comparative studies, such as validating or calibrating ecosystem models (e.g., light use efficiency models, carbon sequestration models) and for assessing the impact of environmental changes on soil moisture patterns and related fluxes. Ultimately, this research aims to contribute to better understanding of carbon fluxes in terrestrial ecosystems and improve land management and climate change mitigation strategies. | 6 |

PhenoCam Images and Derived Time Series Data
PhenoCams are high-resolution digital cameras that take repeated images of studied ecosystems and provide quantitative information about the canopy phenology. The PhenoCam Network coordinates the camera installation and data reporting/analyses across sites in the Americas, providing automated, near-surface remote sensing of canopy phenology across a range of ecosystems and climate zones. Use of PhenoCam images / data should follow the PhenoCam Data Use Policy .

GeoNEX Data Products
GeoNEX led by NASA Earth eXchange (NEX) is a collaborative effort for generating Earth monitoring products from the new generation of geostationary satellite sensors. GeoNEX has produced a suite of geostationary data products including surface reflectance, land surface temperature, surface solar radiation, and many others.
The GeoNEX Common Grid locates GeoNEX data in the geographic (latitude/longitude) projection. Pixels (grid cells) are created at regular 0.005°, 0.01°, and 0.02° resolutions.
GeoNEX pixels below cover the area 0.06° x 0.06° around and including site US-Wwt, 45.1089, -122.6664.
Click a square in the grid at left to display its data below.

About Ameriflux Wind Roses
Wind Rose Explanation
A wind rose gives a succinct view of how wind speed and direction are typically distributed at a particular location. Presented in a circular format, a wind rose shows the frequency and intensity of winds blowing from particular directions. The length of each “spoke” around the circle indicates the amount of time (frequency) that the wind blows from a particular direction. Colors along the spokes indicate categories of wind speed (intensity). Each concentric circle represents a different frequency, emanating from zero at the center to increasing frequencies at the outer circles
Utility
This information can be useful to gain insight into regions surrounding a flux tower that contribute to the measured fluxes, and how those regions change in dependence of the time of day and season. The wind roses presented here are for four periods of the year, and in 16 cardinal directions. Graphics are available for all sites in the AmeriFlux network based on reported wind measurements at each site.
Data from each site can be downloaded by clicking the ‘download’ button.
Hover the cursor over a wind rose to obtain directions, speeds and intensities.
Note that wind roses are not equivalent to flux footprints. Specifically, the term flux footprint describes an upwind area “seen” by the instruments measuring vertical turbulent fluxes, such that heat, water, gas and momentum transport generated in this area is registered by the instruments. Wind roses, on the other hand, identify only the direction and speed of wind.
Where do these data come from?
The wind roses are based on observed hourly data from the sites registered with the AmeriFlux Network.
Parameters for AmeriFlux Wind Roses
To use wind roses for a single AmeriFlux site, the following parameters may be most useful:
- Wind Speed Scale: Per Site
- Wind Direction Scale (%): Per Site
To compare wind roses from more than one single AmeriFlux site, the following parameters may be most useful:
- Wind Speed Scale: Non-Linear
- Wind Direction Scale (%): AmeriFlux
