Overview

Repo with code and supplementary files for STAT 647 final project

Group Members: Sophia, Ethan, Joseph (Minhyuk), and Lizzie (Elizabeth)

Scripts

• generate_figures: script to create isotropic cov function visual
• conus_no2_nngp: script to fit NNGP both with and without covariates
• rf_gls_test: script to fit RF-GLS both with and without covariates

Legacy scripts:

• epa_nngp: script to fit model and generate graphs of EPA data, fits an NNGP with 10 neighors on data for 08/02/2023
• tempo_test: script to read TEMPO nc4 file, graph data, and optionally fit models

Data

• annual_conc_by_monitor_2019.csv
  • All gases from EPA AQS data
  • used in conus_no2_nngp and rf_gls_test for without covariate models
  • url: https://aqs.epa.gov/aqsweb/airdata/download_files.html
• NO2_CONUS_full_data.csv
  • Subset to NO2 only from EPA AQS data
  • used in conus_no2_nngp and rf_gls_test for with covariate models
  • url: same as annual_conc_by_monitor_2019 plus Sophia's processing
• C2930725014-LARC_CLOUD_merged_3nods.nc4: NASA satellite data
  • satellite vertical column density of NO2
  • used in tempo_test, legacy - superseded
