Description: | The Marys River Fir site is part of the "Synthesis of Remote Sensing and Field Observations to Model and Understand Disturbance and Climate Effects on ... The Marys River Fir site is part of the "Synthesis of Remote Sensing and Field Observations to Model and Understand Disturbance and Climate Effects on the Carbon Balance of Oregon and Northern California (ORCA)". Located in the western region of Oregon the Marys River site represents the western extent of the climate gradient that spans eastward into the semi-arid basin of central Oregon. The sites that make up the eastern extent of the ORCA climate gradient is the Metolius site network (US-Me1, US-ME2, US-ME4, US-Me5) all of which are part of the TERRA PNW project at Oregon State University.

The research and science objectives of the Marys River Fir site are as follows: 1) Measurements of carbon, water and energy fluxes in a wet coniferous forest, with ancillary measurements, to understand and quantify biogeochemical cycles in this biome, including carbon stocks and fluxes, water and energy balance; 2) Measurement of carbon, water and energy fluxes across a climatic gradient in the Pacific Northwest, together with Metolius (our group) and Burns (Eastern Oregon Agricultural Research Center) sites to understand climatic effects on plant growth and carbon/water relations; 3) Part of the worldwide Moisture Isotopes in the Biosphere and Atmosphere (MIBA) network: measurement of oxygen isotope composition of leaf water, stem water, soil water and water vapor to understand the hydrological cycle and partition water vapor fluxes between transpiration and soil evaporation; 4) Planned automated measurements of stable isotopes of respired CO2, combined with MIBA measurements, to understand climatic controls on isotopic composition of CO2, and partition photosynthetic and respiratory components of carbon flux.

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-MRf, 44.6465, -123.5515.
Click a square in the grid at left to display its data below.
