goesaodc_createScanSpdf: Create an SPDF from a GOES AOD scan

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

Description

Creates a SpatialPointsDataFrame of AOD readings from a GOES scan file, or a list of SpatialPointsDataFrames from a series of files.

Usage

goesaodc_createScanSpdf(filename = NULL, bbox = bbox_CONUS, dqfLevel = 3)

Arguments

filename	Name of a scan file.
bbox	Bounding box for the region of interest. All points outside of this area will be removed. Defaults to CONUS.
dqfLevel	Allowed data quality level. All points with a DQF value above this level will have their AOD values set to NA. Must be either 0, 1, 2, or 3, with 0 being the highest quality. Defaults to 3.

Value

SpatialPointsDataFrame of AOD values.

Examples

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

bboxOregon <- c(-125, -116, 42, 47)

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

# Create an SPDF from a single scan file
goesaodc_createScanSpdf(
  filename = scanFiles[1],
  bbox = bboxOregon,
  dqfLevel = 2
)

# Create a list of SPDFs from multiple scan files
goesaodc_createScanSpdf(
  filename = scanFiles,
  bbox = bboxOregon
)

# Create an empty SPDF from a faulty scan
goesaodc_createScanSpdf(
  filename = "OR_ABI-L2-AODC-M6_G17_s20202522231174_e20202522233547_c20202522235327.nc",
  bbox = bboxOregon
)
