Layer: Average Daily Sunlight (By County) (0)


Name: Average Daily Sunlight (By County)

Display Field: NAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset presents average daily sunlight (solar insolation) values for counties in the United States, derived from the North America Land Data Assimilation System (NLDAS) and aligned with 2020 U.S. Census county boundaries. The NLDAS sunlight data, available via CDC WONDER, covers daily observations from 1979 to 2011 and includes values reported in kilojoules per square meter (KJ/m²), along with the number of observations and range of values. County boundaries reflect the 2020 U.S. Census Bureau definitions and include population attributes. This integrated dataset supports public health, environmental, and spatial epidemiology research by providing historical solar exposure data at the county level alongside demographic context.
