The polygons in this shapefile identify the boundaries of landscape blocks over which data on snow cover, evapotranspiration, and photosynthetic activity were averaged to represent landscape conditions related to field-based studies at sites across four study areas in the midwestern United States. The polygons were generated by first creating a single grid of square cells, two kilometers on a side, that extended across the entire set of study areas, then selecting those cells (“blocks”) that contained the field sites used in the study (see referenced in the Abstract section). Data representing weekly total evapotranspiration, weekly total normalized difference vegetation index, and week of onset of snowfree conditions from January through August of 2008–2012 are contained in a separate comma-delimited text file and can be linked to the block polygons by the common field “BlockSite.” These data are intended as documentation for the work described in the paper, "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions" (Sadinski, W., Gallant, A.L., Roth, M., Brown, J., Senay, G., Brininger, W., and Stoker, J., Submitted 2017, PLOS ONE). The block polygons in this dataset have no particular significance outside the context of this study.
