If my_address_file_geocoded.csv is a file in the current working
directory with coordinate columns named lat, lon, (within the state
of California) start_date, and end_date then the DeGAUSS
command:
docker run --rm -v $PWD:/tmp ghcr.io/degauss-org/habre_pm:0.2.1 my_address_file_geocoded.csvwill produce my_address_file_geocoded_habre_pm_0.2.1.csv with added
columns:
pm: time weighted average of weekly PM2.5sd: time weighted square root of average sum of squared weekly standard deviation
- Geocoded points are overlaid with weekly PM2.5 rasters corresponding to the input date range.
- For date ranges that span weeks, exposures are a time-weighted average.
library(tidyverse)

Here we will only use row 3 of our test file because it spans two calendar weeks.
