      <abstract>This dataset was constructed from readily available open source climate and vegetation data, like Landsat. This dataset represents the vegetation and climate conditions for a large number of points across the major deserts of the SW USA. The dataset was constructed in order to use the climate pivot point approach (Munson et al. 2013) at the landscape level. Originally this dataset was much larger but we were looking to study a pure vegetation signal and therefore developed a detailed masking procedure to remove fire, slope, human, and floodplain effects. The vegetation classification originally came from SW regap, though we have refined / regrouped the data. The vegetation classification for each point is representative of the dominant vegetation in the 30m area, but by no means is it the only vegetation there. In the pivot point methodology we look to understand how the vegetation production in a single year relates to long term mean production, these columns are included in the dataset. Lastly, this time series data was composited to the warm and cold season since the deserts studied had productivity/ climate events at different times of year. The definition of season is; warm season (July – September),and cold season (October – March).</abstract>
      <purpose>This time series dataset created to develop the climate pivot point approach based on Munson et al. 2013 (see Cross Reference). This time series regression approach looks to pinpoint the climate tolerance for key vegetation across the southwestern United States.</purpose>
      <supplinf>Data users should read the entire metadata record, acquire the manuscript identified as the ‘Larger Work Citation’, and acquire the manuscripts cited therein, to have a complete understanding of how these data were created and used. The data are specific to the uses identified in the ‘Larger Work Citation’ and/or manuscripts cited therein, and any other use of these data would be inappropriate. See 'Distribution liability' statement for more information.</supplinf>
