Spring Indices, 30-Year Average - 30-year Average SI-x First Leaf Date (30yr_avg_4k_leaf)

This layer shows the 30-year average day of year of the first leaf index. These long-term averages were created by averaging the annual Spring Index layers generated for each year in the span 1991 - 2020. These annual grids were generated using historical PRISM data. The Extended Spring Indices are models that predict the "start of spring" (timing of leaf out or bloom) at a particular location. 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. Although these data and associated metadata have been reviewed for accuracy and completeness and approved for release by the U.S. Geological Survey (USGS), no warranty expressed or implied is made regarding the display or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty. Developer Notes: Use the elevation param to specify the day of year.
