The Brooks Field Site 1011 - Ames Site is one of three sites (Brooks Field Site 10 and Brooks Field Site 11) located in a corn/soybean agricultural landscape of central Iowa. The farming systems, associated tillage, and nutrient management practices for soybean/corn production are typical of those throughout Upper Midwest Corn Belt. All three sites are members of the AmeriFlux network. Information for all three can be found in synchronous pages of this website. See MoreShow Less |

The main objective is to develop infrastructure for long-term monitoring of spatial and temporal variation of CO2/H2O vapor exchange and C storage within corn/soybean systems through implementation of a combination field-scale/boundary layer measurement site. Additional objectives include: 1) Comparison of NEE with direct measurement of soil and plant C pools on an annual time step; 2) Determination of agricultural plant contribution to the total CO2 flux; 3) Improve understanding of the complex processes for CO2/H2O exchange at the field and boundary layer scale for the Upper Midwest; 4) Assessment of relative accuracy and feasibility of fluxes measured with the diffusion-gradient technique; 5) Monitor exchange processes at a height where the influence of individual corn and soybean surfaces on the vertical profiles or fluxes becomes horizontally blended.

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 .
No PhenoCam data for this siteGeoNEX 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-Br2, 41.9757, -93.6925.
Click a square in the grid at left to display its data below.
