In shamindras/backburner: A package to extract US Wildfire data and relevant climate features

Description

Wrapper function to generate a single combined or separate SQL files for individual feature NOAA SWDI lagged aggregated time summaries mapped to individual MTBS fires by specified spatial degrees over a 180 day lag period for each fire

Usage

wrap_gen_query_fire_base_swdi_sfeat_180d(
  fire_base_start_date = base::as.Date("2000-01-01"),
  max_lag_fire_base_days = 180,
  spat_deg_rad = 0.5,
  summary_type = "AVG",
  sfeat_types,
  out_qry_dir,
  out_tbl_name_pfx,
  fire_base_tbl_name,
  ind_comb_qry = TRUE
)

Arguments

fire_base_start_date	(date) : The minimum date to filter MTBS fire data, we will i.e. dataset will only contain MTBS fires after this date
max_lag_fire_base_days	(integer) : The number of days for NOAA SWDI weather data to lag behind the fire_base_start_date
spat_deg_rad	(double) : The spatial degree radius to consider around each fire when joining weather data (default value is 0.5)
summary_type	(character) : The SQL summary function to apply to the GHCN-D weather data e.g. "AVG", "MEDIAN" (default value is "AVG")
sfeat_types	(character) : The NOAA SWDI features to summarize for each given fire. Aggregated and lagged versions of each feature are produced e.g. c("nldn", "structure", "hail", "tvs") for generating the code for 2 features
out_qry_dir	(character) : The directory to save the query. A full file path will be generated as part of the output
ind_comb_qry	(logical) : If TRUE then produces a single combined sql query for all features combined. If FALSE then produces a separate sql queries for individual GHCN-D feature

Value

(tibble) : A single or separate SQL files for single GHCN features joined to MTBS fire_ids by specified spatial and temporal parameters
