goesaodc_createScanRaster: Create a raster from a GOES AOD scan

In MazamaScience/MazamaSatelliteUtils: Utilities for Working with Model and Satellite Data as Rasters

Description

Creates a RasterLayer of AOD readings from a GOES scan, file or a RasterBrick of RasterLayers from a series of files.

Usage

goesaodc_createScanRaster(
  filename = NULL,
  bbox = bbox_CONUS,
  dqfLevel = 3,
  cellSize = NULL,
  fun = mean,
  na.rm = FALSE
)

Arguments

filename	Name of a scan file.
bbox	Bounding box for the region of interest. All points outside of this area will be removed and therefore won't be rasterized. Defaults to CONUS.
dqfLevel	Data quality flag level. Defaults to 3.
cellSize	Size of Raster cells measured in degrees lon/lat.
fun	Function used to summarize point values within a single cell. Defaults to mean.
na.rm	Logical flag determining whether to remove NA values before summarizing them with 'fun'. Defaults to FALSE.

Value

RasterLayer or RasterBrick of AOD values.

Examples

library(MazamaSatelliteUtils)
setSatelliteDataDir("~/Data/Satellite")

bboxOregon <- c(-125, -116, 42, 46.5)

scanFiles <- goesaodc_listScanFiles(
  satID = "G17",
  datetime = "2020-09-08 12:00",
  endtime = "2020-09-08 13:00",
  timezone = "America/Los_Angeles"
)

# Create a raster for a scan file
goesaodc_createScanRaster(
  filename = scanFiles[1],
  bbox = bboxOregon,
  dqfLevel = 2,
  cellSize = 0.05
)

# Create a raster from scans averaged over a time range
goesaodc_createScanRaster(
  filename = scanFiles,
  bbox = bboxOregon,
  cellSize = 0.05
)

# Create a raster for a faulty scan
goesaodc_createScanRaster(
  filename = "OR_ABI-L2-AODC-M6_G17_s20202522231174_e20202522233547_c20202522235327.nc",
  bbox = bboxOregon,
  cellSize = 0.05
)
