Singh 20170120 zip files https://doi.org/10.5066/F7DF6PDR Historical (1984-2014) Landsat-based ET maps were generated for Palo Verde Irrigation District (PVID) and eight other sub-basins in parts of Middle and Lower Central Valley, California. A total of 3,396 Landsat images were processed using the Operational Simplified Surface Energy balance (SSEBop) model that integrates weather and remotely sensed images to estimate monthly and annual ET within the study areas over the 31 years. Model output evaluation and validation using gridded-flux data and water balance ET approaches indicated relatively strong association between SSEBop ET and validation datasets. Historical trend analysis of seven agro-hydrologic variables were done using the Seasonal Mann-Kendall test. This study has many applications in planning water resource allocation, managing water rights, sustaining agricultural production, and quantifying impacts of climate and land use/land cover changes on water resources. 20170120 20170201 Done Complete None planned -121.520471 -119.440794 38.110909 36.619888 None Evapotranspiration farming climatology meteorology environment geoscientificInformation historical ET ET modeling thermal remote sensing SSEBop Landsat USGS Metadata Identifier USGS:58869129e4b0cad700058da6 None "Unless otherwise stated, all data, metadata and related materials are considered to satisfy the quality standards relative to the purpose for which the data were collected.
