La Copita Demonstration Ranch is a 2726 acre tract of rangeland located in western Jim Wells County, about 40 miles west of Corpus Christi, Texas and approximately 15 miles south and west of Alice. The ranch is located in a transition zone between the northeastern portion of the central Rio Grande Plain and the Gulf Prairie and Marshes. The climate is subtropical with hot summers and mild winters. Extended cold periods are rare. The growing season is approximately 300 days in length. Annual precipitation averages 716 mm, of which 70% falls in April through September. Three out of five years receive less than average rainfall so precipitation is erratic and droughts are often severe. See MoreShow Less |

The Texas Water Observatory (TWO) is a distributed network of field observatories in Brazos River corridor and was developed to better understand hydrologic flow across natural and manmade reservoirs in the critical zone. The network monitors and measures groundwater, soil water, surface water, and atmospheric water at multiple locations across space and through time. See MoreShow Less |

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-Tx6, 27.6666, -98.2089.
