Data on SO4 atmospheric deposition throughout the conterminous USA

Description

Data on SO4 atmospheric deposition throughout the conterminous USA with object type sf from sf package.

Usage

data(SO4obs)

Format

A sf object. The projection is in Conus (Continental US) Albers, EPSG:5070. The dataframe has 197 observations of a single variable.

SO4

Total wet deposition amounts of sulfate (SO4), in kilograms per hectare in 1987, at sites of the National Atmospheric Deposition Program/National Trends Network (NADP/NTN).

Source

These data were used in the publication listed below. Data were downloaded from the website

(link to: National Atmospheric Deposition Program). It was subsequently converted to sf using st_as_sf function.

The code that creates the data file from the raw data can be found at system.file("raw data/wetSulfateDep/create_SO4obs.R",package = "ZVHdata")
