process_hms: Process wildfire smoke data

In amadeus: Accessing and Analyzing Large-Scale Environmental Data

Process wildfire smoke data

Description

The process_hms() function imports and cleans raw wildfire smoke plume coverage data, returning a single SpatVector object.

Usage

process_hms(date = "2018-01-01", path = NULL, extent = NULL, ...)

Arguments

date	character(1 or 2). Date (1) or start and end dates (2). Format YYYY-MM-DD (ex. September 1, 2023 = "2023-09-01").
path	character(1). Directory with downloaded NOAA HMS data files.
extent	numeric(4) or SpatExtent giving the extent of the output if NULL (default), the entire data is returned
...	Placeholders.

Value

a SpatVector or character object

Note

process_hms() will return a character object if there are no wildfire smoke plumes present for the selected dates and density. The returned character will contain the density value and the sequence of dates for which no wildfire smoke plumes were detected (see "Examples"). If multiple density polygons overlap, the function will return the highest density value.
