A dataset of spatiotemporally sampled MODIS Leaf Area Index with corresponding Landsat surface reflectance over the contiguous US

    This dataset was built to assist a machine-learning-based approach for mapping LAI from 30m-resolution Landsat images across the contiguous US (CONUS). The data was derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6 LAI/FPAR, Landsat Collection 1 surface reflectance, and NLCD Land Cover datasets over 2006 – 2018 using Google Earth Engine.

    LTAR Archbold - University of Florida Phenocam archboldwet

    NAL Geospatial Catalog
      Phenocam overlooking a wetland dominated by Juncus effuses and Panicum hemitomon, Archbold's Buck Island Ranch, Florida. Tracking seasonal changes in greenness in the wetland. Takes RGB and IR photographs daily (every half hour between 6am and 8 pm) and sends them to phenocam network server at https://phenocam.sr.unh.edu/webcam/ where images are available to the public for downloads and processing.

      NAL Geospatial Catalog
        Phenocam overlooking Paspalum notatum – dominated field, Archbold's Buck Island Ranch, Florida. Tracking seasonal changes in greenness of a semi-native pasture, a third of which is burned annually, another one-third is burned in the subsequent year and so on. Takes RGB and IR photographs daily (every half hour between 6am and 8 pm) and sends them to phenocam network server at https://phenocam.sr.unh.edu/webcam/ where images are available to the public for downloads and processing.

            LTAR Upper Mississippi River Basin - Morris - Swan Lake Research Farm Phenocam

            NAL Geospatial Catalog
              The PhenoCam network is collecting color and near infrared images year-round using cameras in fixed positions on agricultural lands including a site located on the Swan Lake Research Farm. The network effort was initiated in 2015 at this long-term, plot-scale research site. The camera at the research farm on focused a plot-scale, replicated research study that was established in 1997 to assess the long-term impacts of various tillage management options on soil organic carbon

              Reynolds Creek Experimental Watershed, Idaho (Lysimeter)

                Lysimeters are instruments that measure water and/or solute movement in soils. The primary purpose for these lysimeters was to measure evapotranspiration (ET); these data describe changes in soil water during the snow-free season. In addition to measuring changes in total soil water, soil water content profiles and soil temperature profiles were measured within or adjacent to the lysimeters and are reported. Two pairs of soil lysimeters were installed in the RCEW in 1967, one pair at the Lower Sheep Creek climate station (designated the east and west lysimeters), separated, center to center, by 3.6 m, and the other pair at the Reynolds Mountain climate station (designated north and south), separated by 4.7 m. These lysimeters were hydraulic weighing lysimeters in which an inner cylindrical tank containing soil is set within a slightly larger outer cylinder.
